2 Trident with SafeVu Trident solid dielectric two way switches now include an innovative visible break feature built into the switch, which eliminates the need to remove elbows or use externally mounted linkage systems to provide a visible open. This makes the Trident with SafeVu ideal for subsurface applications where space and safety practices prevent the linemen from entering the vault to perform these functions. confines of a subsurface vault. The switch can be mounted in any orientation to ease cable training and operation. Oil Fuse Cutout Replacement Eliminate the need to replace fuse links or maintain insulating oil. The Trident with SafeVu does not require any maintenance and features compact size, lightweight, integral visible break, and fault interrupting capability. It is the perfect solution to replace obsolete oil fuse cutouts. Operation The visible break is achieved with a blade type switch incorporated within the solid dielectric module. The blade is in series with the vacuum interrupter and provides a clear visible open. The blade is easily visible through a viewing window molded as an integral part of each module. If the application calls for a resettable fault interrupter, the Trident with SafeVu can be supplied with integral current transformers (CTs) and a self-powered G&W vacuum interrupter overcurrent protection control. The CTs and CT leads are molded within the solid dielectric module, protecting them from the environmental conditions of subsurface vaults. The CTs are dual ratio and preset for either 500:1 or 1000:1. The G&W Type 7 control is particularly well suited for subsurface applications, as it is housed within the Trident mechanism housing. Features Operator Safety All load and fault currents are safely interrupted inside vacuum interrupters molded within solid epoxy insulation. The entire module is coated with a semiconductive layer of epoxy, providing a completely deadfront device, enhancing operator safety. The switch features two mechanical interlocks, external and internal, for safe operation. The external mechanical interlock ensures the switch is operated in the correct sequence. The internal mechanical interlock requires the vacuum interrupter to break all load and fault currents prior to the operation of the visible break switch. Submersibility Trident with SafeVu has been tested to IP68 standards to withstand a 20 foot head of water pressure for 20 days. The switch will remain fully operable after withstanding prolonged submersion at depths of up to 20 feet (6m). Compact, Lightweight Construction - The Trident with SafeVu features a small footprint and is designed to fit through a 27 manhole opening. The small footprint allows installation inside existing subsurface vaults. The switch is much lighter than comparable oil insulated devices, making it easier and safer to install, especially in the tight G&W ELECTRIC PAGE 2 p Viewing windows are molded into the epoxy modules, providing a clear view of the visible break. Ratings The switch is designed, tested and built per IEEE C37.74 for load break switching, IEEE C37.60 for fault interrupting, IEEE 386 for bushing specification, and IEC for environmental protection rating. Certified test reports are available.

6 Options G&W Vacuum Interrupter Controls The control monitors the current, sends a trip signal which opens the vacuum interrupters and interrupts the fault current. G&W controls are self-powered from the current transformers located inside the solid dielectric module. Controls can be equipped to accept a trip input from a relay or communication device. G&W also offers other controls, such as SEL relays, depending on the application. The standard control enclosure for padmount applications is fiberglass NEMA 4X (IP56) rated. For vault and subsurface applications, G&W recommends the Type 7 control. The Type 7 is mounted within the switch s mechanism housing and has an IP68 rating for long term submersion. Type 2 controls offer the following features: Three phase protection - Minimum trip setting for all three phases with one selector switch - Adjustable phase time delay - Ground fault (phase imbalance) for protection of large three phase motors or transformers. The ground trip setting is represented as a percent of the minimum trip setting. - Instantaneous trip and inrush restraint features G&W Control Options Type 2 controls provide a user friendly interface for quick and easy programming. Trip level selections can be made under load or no-load conditions with current ranges in 12 selectable levels. Two ranges of minimum trip settings are available, 15 to 300 amps and 30 to 600 amps. Each unit is pre-programmed with 30 Time Current Characteristic (TCC) curves. The curve selection can be set or changed at any time. An 8 pole dip switch allows the user to choose the TCC curve which best matches their specific coordination requirements. The control can be factory preset to meet the user s requirements. As protection or coordination requirements change, settings can easily be changed in the field. Pressing the manual trip button when the control is powered up trips all three phases of the vacuum interrupter. Each control also includes Last Cause of Trip LEDs. These LEDs indicate what caused the control to issue a trip command - an over current condition, Ground Fault, Instantaneous, or an external or manual trip command. p Type 3 control Type 3 and 4 controls provide advanced protection functions. There are two versions of these controls, each with different protection elements. The EZset version includes: Phase Minimum Trip Phase Time Delay Phase Instantaneous Phase Minimum Response Phase Inrush (Cold Load Pickup) Restraint Ground Fault (Phase Imbalance) Minimum Trip with a Separate Curve 30 Phase/Ground Fault Curve selectors The Plus version includes all of the above, and in addition includes: Ground Fault Time Delay Ground Fault Instantaneous Ground Fault Minimum Response Ground Fault Inrush (Cold Load Pickup) Restraint 60 Phase/ Ground Fault Curves including 5 User Creatable Curves Maintenance Setting Group p Type 2 control The Type 3 and 4 controls record the 16 most recent Cause of Trip Events. The Type 3 EZset includes a display and keypad for entering programming parameters and viewing the Cause of Trip Events. The Type 3 Plus, and Type 4 EZset and Plus utilize a laptop programming kit to enter the settings. The laptop programming kit can also be used to download and store the settings and Cause of Trip Events. G&W ELECTRIC PAGE 6

7 Type 7 controls provide the same protection features and options as the Type 3 and 4 controls, except that the controls are mounted within the switch mechanism housing. This eliminates the need for a separate control enclosure and associated cabling. The control is programmed using a laptop computer. A laptop programming kit is available. Junction Box For auxiliary contacts and remote power/remote trip connections. Includes NEMA 4X (IP56) enclosure with terminal strip connections. Ground Lugs Bronze, eyebolt style ground lugs are available for 4/0 maximum conductor cable. p Type 7 control programming port Programming Kit For Type 3, Type 4, or Type 7 Provides software and cable connection to a laptop computer for programming or retrieving vacuum interrupter control information. The cable connects the USB port of the computer to the Vacuum Interrupter Control (Type 3 or 4) or mechanism housing (Type 7). Catalog Number for Type 3, Type 4, Type 7: LPK7-VICSS Frames Bolted, galvanized mounting frames are available for vertical mounting of vault p Ground lug style switches providing a 24 distance from the ground to the center of the bottom bushing. Other size frames are available. Consult your G&W representative for availability. Bushings Bushings shall be tested to IEEE 386. The switch is available with either 600A deadbreak apparatus bushings or 200A bushing wells. 600A deadbreak apparatus bushings are suitable for use with T-body elbows. 200A bushing wells can be used with 200A load break inserts and elbows. Auxiliary Contacts Auxiliary contacts are mounted within the mechanism housing to provide remote indication of the vacuum interrupter contact position. One normally open and one normally closed Form C contact is provided. p Programming Kit Other Compatible Relays for Overcurrent Protection Various other relays can be provided with Trident switchgear including Schweitzer s model SEL-501, SEL-551, SEL-351S and SEL-751A. Motor Operator Motor operators can easily be mounted on the operating mechanism of switches already installed in the field. Motor operators permit remote operation using a variety of G&W controls. The operating time for a single open or close operation is 2 to 3 seconds. Motor operators are completely submersible and made from cast 304 stainless steel which is permanently bonded and sealed for maximum corrosion resistance. G&W ELECTRIC PAGE 7
