CLAMP CIRCUIT LOCK
• Full Shield miniature circuit breaker lock is suitable for almost all miniature circuit
Product Overview
The Clamp Circuit Lock is a Full Shield miniature circuit breaker lockout device engineered for use in Lockout/Tagout (LOTO) safety programs across industrial, commercial, and utility environments. Constructed from reinforced nylon and copper, it securely immobilises single-pole and multi-pole miniature circuit breakers as well as small-to-medium molded case circuit breakers whose handle thickness does not exceed 8 mm. Its tool-free, clamp-style installation makes it one of the most practical and versatile circuit breaker lockout solutions available.

Product Benefits
Designed to fit virtually every miniature circuit breaker on the market – single or multi-pole – and small-to-medium molded case circuit breakers with handles up to 8 mm thick, eliminating the need to stock multiple lockout devices for different breaker brands.
The clamp circuit lock attaches directly to the circuit breaker handle using its integrated locking screws in a matter of seconds. No drilling, no panel alteration, and no specialised tools are required, reducing downtime and making compliance effortless.
The combination of reinforced nylon and copper delivers exceptional mechanical strength and resistance to industrial chemicals, moisture, and harsh environments – critical for facilities operating in Saudi Arabia's demanding climate conditions.
By positively locking the breaker in the OFF position, the device prevents accidental or unauthorised re-energisation during maintenance, directly reducing the risk of electrical accidents, arc flash incidents, and work-related fatalities.
The padlock-compatible design integrates seamlessly into established Lockout/Tagout programmes, supporting compliance with international standards including OSHA 29 CFR 1910.147, NFPA 70E, and Saudi SASO electrical safety requirements.
