Killark Circuit Breaker Bases & Accessories
External operating handles from Killark are designed to provide door-mounted control for circuit breakers inside enclosures, panel boards, junction boxes and explosionproof housings. Killark replacement handles are used to switch circuit breaker or motor switch units ON or OFF externally without opening the enclosure cover. Common applications include motor starters, lighting branch circuits and panelboards in hazardous or outdoor environments.
Killark handles are a complete assembly and usually consist of an operating button or lever, a bracket or shaft for mounting through the enclosure wall, an interior disconnect lever or paddle and any necessary fasteners. They can be paired with any manufacturer’s compatible power circuit breaker or control circuit disconnect device. Most models can be locked in both ON and OFF positions when used with standard padlocks or safety hasps.
Killark handles are intended to replace original OEM or weatherproof assemblies and are not a repair or spare part. Circuit breaker handles from Killark are constructed with premium materials and have a heavy duty painted, plated or plated finish. Many models are certified explosionproof and dust-tight for use in Class I, II and III hazardous locations. They are designed for harsh industrial environments and are protected from mechanical shock and atmospheric contaminants.
