This product can only be shipped in multiples of 8
Working Mechanism
These GHB Series moulded case circuit breakers incorporate both fixed thermal and magnetic trips.
Fixed Thermal Trips:
Fixed thermal trips are based on the heat produced by the circuit's current flow.
The trip unit contains a bimetallic strip sensitive to temperature changes.
The bimetallic strip heats up and bends as the current rises, tripping the breaker.
Fixed Magnetic Trips:
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.
When the magnetic field intensity reaches a certain threshold, it causes the breaker to trip as the current increases.
