Fehlerstromschutzschalter

Applicable scope Applicable to ac rated voltage isolator, to 380V and rated current - 16 630A circuit, as personal leakage protection devices of the electric circuit, and can be used to protect circuit and power equipment of overload and short circuit, as the line with less frequent transition. Structure characteristics By the operating mechanism, contact system, over-current tripping device, the zero sequence current transformer, leakage tripping and test equipment operating mechanism has to make due to rapid closure and quick touch, disconnect function contactor, speed and operating speeds. Contactor material using silver, nickel, tungsten, graphite paired with small contact resistance, abrasion resistance, good performance characteristics, such as connection to improve the hige capacity.
