1 General Description GHN424NW HHN426N HUN61AW Passed The Test of Time All Murray safety switches have passed rigid testing requirements to assure reliable performance. In addition to tests designed and conducted during the development and manufacturing processes, switches have performed successfully in tests witnessed by Underwriters Laboratories. These tests include those for general purpose safety switches and those designed for more specialized purposes where applicable. Handle Lock-Off Heavy duty, H series safety switches have a provision to lock the handle in the OFF position with a maximum of three padlocks. Doors may be locked closed with a padlock. General duty, G series switches may be locked in the OFF position with one padlock. There is also a padlock feature for locking the door. General and Heavy Duty Switches Feature a Time Proven Design A fast, long lasting switch design with a clean, continuous contact. That s the switching system that gives you on-going reliability. The concept is simple: split the arc to shorten the break distance. Uncomplicated mechanics and common sense design assure reliable performance time after time. All switches through 1200A feature visible blade contruction. Load Break Ratings All Murray safety switches are UL Listed for load break applications. Included in this process is a series of repeated make and break tests of the switch contacts while carrying the full rated nameplate current and rated voltage. Horsepower Ratings Where permitted, all Murray safety switches are UL horsepower Listed. The switch ratings are determined by tests that have been performed successfully in the UL overload test series, including repeated make and break tests of the stalled motor current of the motor for which it is being rated. Some switches have two or more ratings for a particular voltage and current, and additional ratings if designed for multi-pole applications. Depending on the switch and its application, various ratings may be assigned. All switches list the ratings on the inside of the cover or the door. The ampere rating and maximum AC voltage rating are always shown on the nameplate on the front of the switch. Fault Current Performance Murray Heavy Duty safety switches have successfully passed UL high level fault current tests. This means the risk of mechanical and thermal damage due to high level short circuit currents is minimized due to the reliable switch design. Suitability tests for service with Class H, R, J, L, and T fuses have been conducted on heavy duty safety switches. Representative switches, with test fuses connected in series with each switch, were subjected to let-throughs in excess of the capacities of the largest fuses acceptable by the switches. To pass the test, the switch must remain operable after being closed into a high amp available short circuit current. The test fuse is sized so that higher levels of let-through current and energy will be reached than would ever occur during normal usage in the field. Murray General Duty safety switches have been tested to allow installation on circuits capable of delivering 100,000 AIC of fault current at 240V AC max. with Class R fuses and also with both Class J and T fuses in A ratings. Fuse Interchangeability General Duty Switches, Prefix G,* will accept the following UL class fuses: Class H Class K Class R Requires class R fuse kit to maintain UL listing. Class J A field convertible. Class T with proper adapter kit ( A). *Except 0 amp plug style switches. Heavy Duty Switches, Prefix H, will accept the following UL class fuses: Class H Class K Class R Requires class R fuse kit to maintain UL listing. Class J All 0 200A, 600V and A, 240V switches field convertible. Class L 800 and 1200A switches only. Class T A switches with proper adapter kit. Gutter Space G and H series safety switch gutter dimensions conform to 2008 NEC Article #12.6(A). Top and bottom gutters conform to Table #12.6(B). MURRAY -9

2 Technical Information MURRAY General Duty Switches; Prefix G General duty switches are available in indoor TYPE 1 and outdoor TYPE R enclosures. Enclosures can be locked closed and operating handles can be locked off. Series G switches have a quick-make, quick-break mechanism. Fusible switches are available in 1 pole S/N, 2 pole S/N and pole S/N configurations. Non-fusible switches are available in pole configurations. General duty switches are limited to 240V AC, 200 max. rating. All 0 Amp compact fusible and non-fusible G prefix switches are rated 10,000 Amp maximum withstand. All Amp GF and GU prefix switches are suitable for use on systems capable of delivering not more than 100,000 RMS symmetrical of fault current with Class R fuses and the appropriate adapter kit installed. These Amp G prefix switches may also be used on systems capable of delivering not more than 100,000 RMS symmetrical of fault current with T fuses and the appropriate adapter kit installed. In addition, general duty switches may also be used with J fuses on systems not capable of delivering more than 100,000 RMS symmetrical amperes of fault current. General duty switches are UL Listed for use as service equipment and are horsepower rated for use with motor loads. General duty enclosed switches are used for light duty applications where loading and switching operations are not excessive. Heavy Duty Switches, Single Throw; Prefix H Heavy duty switches are available in indoor TYPE 1, outdoor TYPE R, Watertight Type 4/4X, and industrial TYPE 12 enclosures. Dual cover interlocks are provided, such that the door cannot be opened with the switch ON and the switch cannot be turned ON with the door open. A defeat mechanism allows servicing by authorized personnel. Handles may be locked OFF with up to padlocks, and doors may be padlocked closed. Mechanism is TEASE-PROOF quick-make, quick-break. Fusible switches are available in 2 pole S/N, pole and pole S/N. Non-fusible switches are available in pole. Suitable for use on systems capable of delivering not more than 200,000 RMS symmetrical amperes of fault current when Class J or R fuses are installed except the 800 and 1200A switches, which are suitable for use on circuits capable of delivering not more than 200,000 RMS symmetrical amperes of fault current when Class L fuses are installed A switches with Class T fuses and field adapter kit 200,000 RMS symmetrical rated. Heavy duty switches are dual horsepower rated and are listed by UL for use as service entrance equipment. Heavy duty switches are intended for applications where rugged construction, reliable performance, continuity of service and ease of maintenance are required. Protector-Lock Switches; Prefix H The Murray Protector-Lock switch is designed to eliminate shock hazard due to disconnecting heavy duty portable electrical equipment under load. When the switch is in the ON position, the safety bar blocks the self-contained receptacle and prevents insertion or removal of the plug. When the switch is OFF, the bar retracts, allowing insertion or removal of the plug. Protector-Lock switches consist of a heavy duty, 0 or 60 Amp, 600V AC, pole fusible or non-fusible enclosed switch, and either Crouse-Hinds or Arrow Hart Industrial receptacles. Applications include industrial plants where portable conveyors and welders are used, and truck terminals where on-board refrigeration units require stand-by power. Double Throw Switches; Prefix HD Double throw switches are available in TYPE 1 and TYPE R enclosures. Covers are dual interlocked with the operating mechanism such that the cover cannot be opened when the switch is in either ON position, and the switch handle cannot be moved to either ON position if the cover is open. Handle may be padlocked in the OFF position. Switching action is quick-make, quick-break in both ON positions. They are available in Amp ratings, 240V AC, fusible and non-fusible, two and three pole. Double throw switches are usually applied as transfer switches to switch a load from one power source to another, but can be field converted to switch one power source between two loads. Switching mechanism is located on line side of fuses allowing for a safer fuse replacement. All are suitable for use as service equipment.
