3 Features, Benefits and Functions Visible double-break quickmake, quick-break rotary blade mechanism. Two points of contact provide a positive open and close, easier operation, and also help prevent contact burning for longer contact life Triple padlocking capability. Personnel safety feature since the large hasp can accommodate up to three 3/8-inch (9.5 mm) shank locks. Cabinet door can be further padlocked at the top and bottom Interlocking mechanism. Door cannot be opened when the handle is in the ON position. Built-in defeater mechanism provides for user access when necessary Deionizing arc chutes; arc chutes confine and suppress the arcs produced by opening contacts under load Mechanically interlocked cover to prevent easy access when the switch is in the ON position Clear line shield with probe holes Clearly visible palm fitting red handle Tangential knockouts on NEMA and NEMA 3R Built-in fuse pullers on NEMA X and NEMA 2 Additional door locking capability Complete accessory and renewal parts data shown on inner door label A NEMA 2 designs convertible to NEMA 3R by opening factory-installed drain hole A switches are seismic qualified and exceed the requirements of the Uniform Building Code (UBC) and California Code Title 2 Tri-lingual nameplates All general-duty switches above 00A and all heavyduty switches incorporate these K-Series switch design features. Two points of contact provide a positive open and close, easier operation, and also help prevent contact burning for longer contact life Visible Double-Break Rotary Blade Mechanism Protects against accidental contact with energized parts. Probe holes enable the user to test if the line side is energized without removing the shield. Not typically provided on general-duty switches, but available as a field kit or factory installed Clear Line Shield Provide easy removal of fuses Built-In Fuse Pullers (NEMA 2 and X A Only) The position (ON or OFF) can be clearly seen from a distance and the length provides for easy operation Clearly Visible Handle Personnel safety feature since the large hasp can accommodate up to three 3/8-inch (9.5 mm) shank locks Triple Padlocking Capability Cabinet door can be further padlocked at the top and bottom as applicable Additional Locking Capability Door cannot be opened when the handle is in the ON position. Front and side operable defeater mechanism provides for user access when necessary on singlethrow switches An ample number are provided on the top, bottom and sides of both NEMA Types and 3R Tangential Knockouts For switches in a NEMA Type 3R, A.
