Working Mechanism
- These frames enclose C series moulded case circuit breakers that incorporate both fixed thermal and magnetic trips.
- Fixed thermal trips are based on the heat generated by the current passing through the circuit.
- The trip unit contains a bimetallic strip sensitive to temperature changes.
- As the current increases, the bimetallic strip heats up and bends, triggering the breaker to trip.
- Fixed magnetic trips use the strength of the magnetic field created by the current passing through the circuit.
- The trip unit contains an electromagnet sensitive to changes in magnetic field strength.
- As the current increases, the magnetic field strength increases and when it reaches a certain level, it triggers the breaker to trip.

Fixed Magnetic Trips
