4 Vacuum Contactor Module The vacuum contactor module was designed with operator and maintenance personnel in mind. It incorporates distinctive features for ease of installation, operational safety and maintenance simplicity in the Advance TM medium voltage motor control center (MVMCC). For improved safety, the interlocking system prevents opening the isolation switch while the contactor is closed, opening the cell door when the switch is closed, and operating the isolation switch with the door open. The contactor can only be energized with the door closed. The isolation switch is manually operated and interlocked, and the front window allows air gaps in the switch to be visibility verified. The contactor/isolation switch system includes all necessary interlocks to assure proper sequencing and safe operation. Also, an auxiliary switch is available to indicate open or closed position. The contactor enclosure includes stationary support and primary contacts for engagement with the contactor. Padlock provisioning is provided for securing the contactor in place. Easy access to the contactor module improves maintenance and operation. Ratings Contactors are rated at 400 A & 720 A Two-high design with 400 A contactors without de-rating the upper cell 3

5 Vacuum Contactor Truck Assembly Vacuum contactor and power fuses are mounted on a removable truck to allow for simplified maintenance and safe handling Parts requiring service are mounted on the truck for inspection, away from energized equipment for ease of use A lifting device latches to the contactor module for simple and safe extraction of the contactor, and can be adjusted to fit the compartment height Position of the switch and air gap between contacts can be visually verified from the front viewing window reassuring the user that the cell is de-energized Maintenance work, such as exchange of fuses, can be conducted with the contactor locked in place inside the cubicle with the isolation switch in the open position Blown fuse indicators on the power fuses are visible through the front viewing window with the door closed and equipment energized Front view, Back view of contactor module Mechanical tripping device for latching contactor 4

6 Low Voltage Instrument Module Dedicated low voltage compartment for protection and control devices Low voltage compartment completely isolated from the high voltage components Devices and control switches mounted on low voltage door for readability and access Various configurations allow for 19, 38, & 57 tall modules, providing flexibility and ample space Low voltage instrument modules are isolated for maximum safety when working with LV circuits Main Bus Main bus ratings are available in 1200 A, 2000 A & 3000 A Flame-retardant insulation provides resistants to tracking Silver or tin plated for aggressive environments Removable/reusable boots for protection and ease of inspection Bus is front accessible via low voltage compartment Main Bus Access AdvanceTM medium voltage motor control center (MVMCC) is 100% front accessible allowing back-to-back or back-to-wall placement, saving floor space 5

7 Safe Handling & Reliability Ease of Use Simplified Maintenance Manual Secondary Disconnect system 25 Pin secondary disconnect for control circuitry is easily accessible for testing starter operation Polycarbonate Shields Safely block access to energized components and isolation switch Shield cable terminations and terminal blocks Power Cable Hookup Top or bottom entry via grounded metal duct Ample Space for cabling with room for stress cones Easily accessible cable standoffs simplify power cable installation Polycarbonate shields protect terminal blocks and provide added safety Contactor Grounding Ground bar accessible from the front Flexible connector pro vides a grounding connection to ensure effective and safe operation of the truck assembly Safty Interference by Design Contactor enclosure sized to prevent insertion of improperly rated controllers for fail safe maintenance operation 400 A contactor will not line up in a 720 A enclosure ensuring operator safety 6

8 Materials and Construction Advance TM medium voltage motor control centers (MVMCCs) use 14-gauge pre-coated Galvalume material throughout Galvalume does not require painting due to its superior resistance to corrosion and self-healing characteristics Hem bends create a rigid self-supporting structure, reducing sharp edges inside the cubicle, minimizing the risk of injury Bolted modular design and double-side wall construction allow for easy system extension and maintenance Excellent product quality results from the best materials and design. Auxiliary Primary Modules ABB potential transformer modules accommodate industry-leading ABB VIY-60 kv BIL potential transformers and are rack mounted in a 19 module Each standard module accepts up to three PTs with line-to-line (L-L) or line-to-ground (L-G) connections Optional 75 kv BIL type PTs accept up to two transformers mounted in a 38 module PTs are automatically grounded when withdrawn to discharge any residual current Standard 60 kv BIL 1000 masl Accessories The accessory group for Advance TM medium voltage motor control centers (MVMCCs) and the ABB vacuum contactor include a complete array of required and optional special tools for proper handling, operation and maintenance. For maximum convenience, all withdrawable assemblies potential transformers, control power transformers, and fuses use the same accessories. 7

9 Lift Truck Lift truck is required for all primary devices Lift truck docks with the MVMCC Lift truck has wheels for easy maneuvering Motor lift optional All primary devices have self-contained wheels for easy floor rolling Test Jumper Test jumper is an extension cord Allows connection of secondary contacts on a vacuum contactor to the MVMCC while outside a contactor compartment Enables the contactor to be electrically operated using controls in the MVMCC, or electrically charged after manual operation of the contactor. Test Cabinet Test cabinet is a wall-mounted control cabinet connected to a separate power source and contains switches to open and close the contactor Test cabinet has a female connector and an umbilical cord (stored inside the cabinet) for connection to the contactor Serves as an aid to contactor inspection and maintenance in MVMCC aisles or work areas Ground Device Ground device is a removable assembly compatible with MVMCC compartments Ground device provides a means of selectively grounding de-enrgized primary load circuits to the MVMCC ground bus to support maintenance activities Ground device can then be padlocked in the connected position in accordance with lock-out and tag-out safety proceedures 8
