WebThe magnetic part is designed to trip near-instantaneously, and the current at which it trips depends on the type. Type B Trips between 3x and 5x the rated current. Example - a 6A circuit breaker would need between 18A and 30A before it trips. Type C Trips between 5x and 10x the rated current. For this circuit, you must wire breaker control relay’s ‘a’ contact in series with a string of 86 lockout relay ‘b’ contacts before you hit the anti-pump relay in the close circuit. Why?
