STRO07-40 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.
