Circuit Breaker Lockout

The Circuit Breaker Lockout secures miniature and moulded-case circuit breakers firmly in the off position, preventing accidental or unauthorised re-energisation during electrical maintenance. Available in clamp-on, pin-in and tie-bar formats to suit single, double and multi-pole breakers, it fits a wide range of switch profiles without tools and accepts a safety padlock for positive, auditable isolation.

Product Description

The Circuit Breaker Lockout addresses one of the most common electrical isolation needs on any site: holding a tripped or switched-off breaker securely in the safe position so it cannot be reset while work is underway. The range covers the full spectrum of breaker styles, from clamp-on and pin-out devices for standard miniature circuit breakers to wide-body clamps and tie-bar assemblies for moulded-case and multi-pole breakers. Each device grips the toggle or switch firmly, resisting vibration and tampering, and provides a shackle hole for a safety padlock so the isolation is both physical and clearly attributable to the responsible worker.

Moulded from tough, non-conductive thermoplastic, these lockouts are lightweight, quick to fit without tools and resistant to the heat and humidity typical of GCC electrical installations. Universal and breaker-specific designs ensure a secure fit across distribution boards, control panels and switchrooms, while some variants accommodate the pin holes found on many breaker toggles for a positive mechanical lock. Widely used by electrical contractors, facilities teams and plant maintenance crews across the UAE, Saudi Arabia and the wider GCC, the Circuit Breaker Lockout is a compact but critical component of compliant lockout-tagout, protecting technicians from unexpected re-energisation during panel work, testing and repairs.
