Circuit breaker switch lock is mainly used to prevent the sudden start of electrical equipment during maintenance and protection of personal safety. Our circuit breaker lockouts isolate and secure almost any circuit breaker switch. Provides snap-on and clamp-on options covering most circuit breakers. Oversize clamp-on and universal multipole breaker safety locks are also available. It should be noted that the breaker switch lockout only ACTS as an isolation device. To lock the circuit breaker and mark the isolation state, it must be used in conjunction with the safety padlock and safety tag of LEDS.

Molded case circuit breaker lockouts are different from miniature circuit breaker lockouts
The difference between a molded case circuit breaker and a miniature circuit breaker: Both a miniature circuit breaker and a molded case circuit breaker belong to a circuit breaker and work on the same principle. The difference lies in: 1. The miniature circuit breaker installation way is the guide rail installation, the molded case circuit breaker is the screw installation; 2. The maximum current level of the miniature circuit breaker is within 63A, and the current level of the molded case circuit breaker is up to 2000A. The main point of the plastic case circuit breaker is basically only a switch handle, and the micro circuit breaker may have many poles, so decide its locking mode is not the same as the micro.

Use Method Of Breaker Switch lockout

Due to the different structure of various breaker switch lockout, their installation and use methods are also different;
Push button type: there are three types: pin in, pin out and pin out wide; For miniature circuit breakers with holes on both sides of the handle, without any tools, just press the button to insert the bottom two pins into two holes of the circuit breaker, and then fasten the safety padlock and safety tag;
