2 Application ata escription eavy uty Safety Switches may be used as a means for disconnecting a load from its supply, or for opening and closing a circuit. hen equipped with fuses, overload and short circuit protection are also provided. Application eavy uty Safety Switches are designed for the following applications: Commercial and industrial installations. Up to 600 Vac or 600 Vdc maximum. Up to 200,000 rms symmetrical amperes short circuit current. 30 through 1200 amperes. orsepower ratings. Two or three fusible switched poles with or without insulated, groundable neutral. Four fusible switched poles, neutral not available. Two or three not fusible, switched poles with or without insulated, groundable neutral. Four not fusible switched poles, neutral not available. Six not fusible switched poles, neutral not available. Standards eavy uty Safety Switches are manufactured in accordance with these standards. UL98, Standard for Safety, Enclosed and ead Front Switches. UL Listed under File E2875, or E NEMA Standards Publication KS1, Enclosed Switches. Federal Specifications S-865c for Type. CSA Certified C22.2 No.4. NOM Certified. Red and black handle indication for switch position. E Series F Series F Series handle/lockplate is field replaceable. F Series RB devices have side opening covers. ighly visible ON-OFF marking. Quick-make, quick-break spring driven operating mechanism. F Series operating mechanism is a field replaceable, enclosed modular design. Construction Visible blades for positive blade position.

Copper only cable termination on NEMA Type 12, 12K or 4, 4X, 5 stainless steel. Class J fuse provisions on 30 through 600 ampere, 600 volt switches and 100 through 600 ampere, 240 volt switches. 600 ampere devices require a mounting kit. Mechanical Lugs ual cover Interlock keeps the cover shut when switch is ON. hen the cover is open, it locks the switch OFF, unless a qualified person bypasses the interlock. Class J Fuse Provisions Alternate mounting holes make for easy conversion to Class J fuses. 30 through 600 ampere switches are shipped with standard Class fuse spacing. Multiple padlock provision in OFF position. Interlock Bypass Factory installed fuse pullers on 30 through 100 ampere NEMA Type 4, 4X and 5 stainless steel and NEMA Type 12 or 12K switches. Field installable on 30 through 100 ampere NEMA Type 1 and NEMA Type 3R switches manufactured after February, Lock-off Provision Fuse Pullers 3

Box Coupling evice 1 2" through 4" zinc or chrome plated watertight hubs for field installation on NEMA Type 3R, 12 or 4, 4X, 5 stainless steel switches. Accessories Bolt-on hubs for rainproof applications. Switches with RB suffix accept 3 4" through 2 1 2" bolt-on hubs. Switches with R suffix have blank top endwalls. RB devices may be coupled to raintight trough with a box coupling. F Series RB devices are compatible with 4" raintight trough only. atertight ubs Class R fuse kits for systems up to 200,000 rms symmetrical amperes provide rejection for all other fuse types. Bolt-On ubs Class R Fuse Kits 4
