Product Description

Miniature Circuit Breakers (MCB) which can be used in low voltage electrical installations to protect conductors, switchgear, and electrical equipment in general against overload and short-circuit.
Each phase of conductor at the circuit breaker passes through the zero-sequence current transformer, and the secondary side of coil connects with the electromagnetic tripper. Under normal condition, the vector sum of each phase of current passing through zero-sequence current transformer is zero. The flux of the zero-sequence current transformer is zero. And the secondary output voltage is zero and the circuit breaker doesn't zero, and the zero-sequence current transformer would produce the magnetic flux, and the secondary side of coil would output the voltage. Once the leak current increases to drive the output voltage at the secondary side to grow to certain level, the electromagnetic release would activate to drive the operation mechanism to act to break the contact that connects the power, finally to realize the leak protection.
