HSV1 series intelligent low voltage vacuum circuit breaker

It is mainly used in AC 50Hz, rated working voltage 400V, 690V, rated working current 630A to 3200A in the distribution network, used to distribute electric energy, protect the line, prevent the power supply equipment from being overloaded, under voltage, short circuit and single phase grounding. harm. It can also be used as an infrequent conversion of lines under normal conditions. The core components of the circuit breaker are equipped with intelligent controllers with precise selective protection to avoid unnecessary power outages and improve power supply reliability. The biggest feature of the circuit breaker is that it uses a vacuum interrupter, and there is no arc discharge during the breaking current, so it is especially suitable for places with poor environmental conditions such as coal mine, chemical industry and smelting.

Compared with the air circuit breaker, the circuit breaker has a long service life, a short circuit breaking number, a strong arc extinguishing capability, and a true zero arcing. It can be used in places where the current air circuit breaker is unable or unsuitable for use (such as high reliability of power supply; no frequent power failure overhaul; frequent operation; places with harsh environmental conditions such as fire and explosion hazard). The HSV1 series of intelligent low-voltage vacuum circuit breakers meet environmental and safety requirements.

The product complies with GB 14048.2 - 2001 "Low-voltage switchgear for low-voltage switchgear and control equipment" and IEC 60947-2 "Low-voltage switchgear and control equipment breaker" and other standards.
