Heavy Duty Safety Switches

Transcription

1 eavy uty Safety Switches 240 Volt Class 110 Visible blade heavy duty safety switches are designed for application where maximum performance and continuity of service are required. All heavy duty safety switches feature quick-make, quick-break operating mechanism, a dual cover interlock and a color coded indicator handle. They are suitable for use as service equipment when equipped with a field- or factory-installed neutral assembly or equipment grounding kit, unless a 0Y/47 V or 480 Y/277 V, 0 A or greater, solidly grounded YE system is used, per NEC eavy duty safety switches are UL Listed (except as noted), File E2875 & and meet or exceed the NEMA Standard KS1. For UL Listed short circuit current ratings, see page -6.

Class R Fuse Provisions: Fusible Square 0 A heavy duty safety switches will accept Class R fuses as standard. A field-installable rejection kit is available which, when installed, rejects all but Class R fuses. ith the installation of the rejection kit and Class R fuses, the switch is UL Listed for use on systems with up to ka available fault current. See Class R fuse kits on page -9. Class J Fuse Provisions: Provisions for installing Class J fuses are included in through 400 A 0 Volt, and through 400 A 240 Volt, fusible heavy duty safety switches. Conversion to Class J fuse spacing requires relocating the load side fuse base assembly from the standard Class fuse location to an alternate position as marked in the enclosure. ith Class J fuses installed, the switch is UL Listed for use on systems with up to ka available fault current. Switches rated 0 A, 240 or 0 Volt, require the addition of an adapter kit, 0J at $4. One kit per P switch.
