A singleunidirectional movement of the handle closes the switch and charges anopening operator features a spiral closing spring and an independentopening spring.

3 This design results in greatly reduced handle effortwithout sacrificing blade speed. The spring guide is containedcompletely within the housing. Key interlock can be achieved within thesame switch switch blade movement is Quick Make, Quick Break andcompletely independent of handle SHUNT trip operated switches unequivocally meet NEC Article380-7. When the switch is closed, the handle is up and blocks the fusedoor. When the switch is open, the handle is down, allowing easy tripped, the handle may be used for breaking welds, as required by some design handle is trip free. The handle is not driven down, but falls to theopen position by gravity. Blocking the handle does not interfere with themechanism opening the VL, VLB, SL and SLB models have a Position Indicator featurewhich shows the true position of the 104 BPAGE 2 The main switch and branch switches shall be of the fusible bolted pressure type of ampacity as shown on thedrawings.

4 Switches shall be dead front, and equipped with Quick Make, Quick Break tease proof OPERATORS . Anon-metallic insulated bar will be used to connect the operator to the crossbar, in order to keep ground potential outof the arcing zone. The operating handle shall have provisions for padlocking in the open position with at least 600 amp and smaller shall accommodate Class J or R larger than 600 amp shall accommodate Class L or T switches 400 through 4000 amp shall have met the test requirements of UL 98 and/or UL 977, and markedsuitable for use on a circuit capable of delivering 200,000 RMS symmetrical suitable for use with Class I ground fault sensing element shall be equipped with SHUNT trip OPERATORS and shall have a current interrupting rating of 12 times the nameplate rating.

5 The operating mechanism shall be such thatat the moment when the switch contacts close, the operating mechanism shall immediately be in a condition to openthe switch contacts by the electrical tripping means without further operation, manual or bolted pressure contact switches shall be manufactured by BOLTSWITCH, INC. of Crystal Lake, SPECIFICATIONS FOR SWITCHES WITH SHUNT trip OPERATORSSHUNT trip OPERATORSBULLETIN 104 BUL PERFORMANCE REQUIREMENTSA brief description of some of the tests required by the Underwriters Laboratories, Inc., prior to listingswitches with electrical trip mechanisms, are as follows: trip at 75% of coil rating; trip at 55%of coil rating if intended for use withground fault sensing break operations at 10 times ratedcurrent, at rated voltage; 3 breakoperations at 12 times rated currentat rated voltage if intended for usewith Class I ground fault sensingequipment without load endurance test operations:OPERATION:CIRCUITOPENING:ENDU RANCE:SWITCH RATING IN AMPERESNUMBER OFOPERATIONS4006008001200100100505030-12 00 AMP SWITCHES (UL 98) trip at 75% of coil rating; trip at 55%of coil rating if intended for use withground fault sensing equipment.
