125A High Quality STFP60-125 2P,4P Single ,Three Phase 230/400V
RCCB Circuit Breaker A or AC model IEC61008 Standard
The RCCB is mainly suitable for use in variety of plants and
enterprises, building construction, commerce, guesthouses and
families, it can be used in circuits up to single phase230V, three
phase 400V 50 to 60 Hz. RCCB is also suitable for use on DC pulse
system.
Description
Residual Current Circuit Breaker with Over Current Protection is
used to protect against electrical leakage in the circuit of
50/60Hz, rated voltage 230/400V,rated current up to 40A.
When electirc shock happens or the residual current more than the
fixed value, the RCCB can cut off the power within 0.1s
automatically protecting the personal safety and preventing the
equipement from the fault resulted from the residual current.
So the RCCB can protect the circuit against overload, short circuit
and electrical leakage
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.
