A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or auto

Electro-mechanical Trip Unit (continued) Deflection is predictable as a function of current and time. This means, for example, that a typical 100A breaker might trip in 1800 seconds at 135% of rating (Point A) or of rating (Point B). The magnetic trip portion is used for short circuit (instantaneous) protection.

The performance state evaluation method of circuit breaker energy storage spring mainly judges its performance state indirectly by measuring the pre-tightening force or pre-pressure of the spring. However, there may be some errors in this indirect measurement method, which will affect the accuracy of the evaluation results. Therefore, the performance state
