ARBOSS

Auxiliary contacts for the NH40 series toggle switch are designed for AC networks of 50/60 Hz frequency, rated voltage 690 V with a rated current of up to 630 A. They are used in low-voltage switchboard equipment for distribution and protection against overload currents, short circuits, including single-phase ground faults. Due to the presence of multifunctional units based on microprocessor modules in the switches, the distribution and protection systems for networks of industrial enterprises, residential and administrative buildings, especially in the equipment for the distribution and protection of power supply systems of high-rise buildings, are used in transformer substations and main switchboards.
