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.
