Industrial Switch for Hazardous Areas

The Killark FXS-51C is a single-gang tumbler switch rated for 20 A at 120 to 277 V AC. It carries NEMA 3, 7C, 7D, 9E, 9F, and 9G ratings plus CSA and UL listings for use in classified locations. The 1-pole toggle controls one circuit with clear On/Off legend markings.

Feed-Through Hub and Pad-Lockable Toggle

A 3/4 in feed-through hub allows straight conduit runs while mounting holes provide secure surface attachment. The toggle can be padlocked in either the On or Off position to support lockout-tagout procedures. Rated at 1 hp at 120 V AC and 2 hp at 240 V AC, it suits motor loads as well as lighting circuits.

Replaces Standard Switches in Classified Zones

This unit replaces general-purpose switches where NEMA 3, 7, or 9 enclosures are required by code. The jump is worth it when an installation demands third-party listed protection against ignitable gases, vapours, or dusts and a lockable actuator for safety compliance.
