Air Switch Household Miniature Current Circuit Breaker 3P Overload
Protector
Product Description
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 zreo, 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.
Application
The product is suitable for the line of AC 50/60Hz,voltage
240V(2pole)/415V(4pole), rated current up to 63A. When there is
human electricity shock or if the leakage currentof the line
exceeds the prescribed value, it will cut off the power rapidly to
protect human safety and prevent the accident due to the current
leakage. It can be used as infrequent changeover of the line in
normal situation.It is applicable to industrial site,commercial
site, tall building and civil house.
It complies with standard of IEC/EN61008.1 and GB16916.1.
