Product Description
18mm width Intreruptor diferential 1P+N RCBO Type A or Type AC Residual Current Circuit Breaker with Overcurrent Protection AC 230V 4.5/6KA
STRO-40L series residual current circuit breaker is in conformity with the standards of IEC61009.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 240V,three phase 415V,50 or 60Hz.



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.
