STEZ9-63L series Electronic ,magnetic type residual current device
;A or AC model automotive circuit breaker up 63A 30mA
2P 4P Electronic (Magnetic)Type Residual Current Circuit Breaker STEZC-63L series is in conformity with the standards of IEC61008.It can cut off the
fault circuit immediately on the occasion of shock hazard or earth
leakage of trunkline.Thus it is suitable to avoid the shock hazard
and fire caused by earth leakage.It can be used in circuits up to
single phase 230V,three phase 400V,50 or 60Hz.
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.
And It complies with standard of IEC/EN61008.1
Product Over View:
1. Provide protection against earth fault/leakage current and
function of isolation
2. High short-circuit current withstand capacity
3. Applicable to terminal and pin/fork type busbar connection
4. Equipped with finger protected connection terminals
5. Automatically disconnect the circuit when earth fault/leakage
current occurs and exceeds the rated sensitivity
6. Independent of power supply and line voltage, and free from
external interference, voltage fluctuation.
