Product Description

HLVP-12 (VS1) Indoor Speedy High Voltage Vacuum Circuit Breaker

Product Description

Product overview

HLVP-12 sealed vacuum circuit breaker
High voltage switchgear for protection and control in three-phase power systems with rated voltage 12 kv and frequency 50 Hz Electrical appliances, due to the special advantages of vacuum circuit breakers. especially suitable for frequent operation under rated operating current, or repeatedly break short-circuit current places.
Operation of HLVP-12 sealed vacuum circuit breaker
The integrated design of the moving mechanism and the circuit breaker body can be used as a fixed installation unit or a special propulsion mechanism to form a handcart unit.

Indoor fixed type enables the circuit breaker to perform stably,and extend its service life.The mature technology of sulfur hexafluoride as an arc extinguishing medium is adopted,making the work safe and efficient.
