CMLHPB111-1RLS4R-38097-225-V Circuit Protection

The working principle of the CMLHPB111-1RLS4R-38097-225-V is based on two individual components, the thermal overload component and the magnetic short-circuit component. The thermal overload component is activated when the circuit breaker system detects an overload current that is too high for the current rating of the circuit breaker. When this happens, the breaker releases a thermal expanding element that causes the breaker to trip. The magnetic short-circuit component, on the other hand, is designed to work in combination with the thermal element, by creating a current that is proportional to the short-circuit current. When the current reaches a certain point, the breaker trips in order to protect the system from further damage.
