15kv 1250a VCB Vacuum Circuit Breaker

This high quaity 15kv 1250a vcb vacuum circuit breaker from SYHF is based on user-centric design for safer and more stable operation and improved insulation performance through solid insulation of integrated isolation barriers and molded vacuum interrupters. The vacuum circuit breaker is equipped with a high-speed spring assist mechanism, which allows fast closing and fast opening operations with a tripping time of no more than 3 cycles. The circuit breaker has multiple interlocks and safety features built in. It provides stable power supply to all industrial fields including power plants, chemical plants/steel plants and construction facilities. This is a new type of circuit breaker with short arc time and short circuit and ground fault power-off time, which can achieve maintenance-free.

15kv 1250a vcb vacuum circuit breaker Features:

15kv 1250a vcb vacuum circuit breaker adopts high-quality contact materials and shapes, lower current carrying capacity and stable contact resistance.

It adopts composite insulation material and integrated design of the main conductive circuit of the operating mechanism.

15kv 1250a vcb vacuum circuit breaker has a small number of parts, compact and reasonable structure, and more reliable and safer operation.

The compact design allows the circuit breaker to be installed in almost all switch cabinets.

Difference between vacuum contactor and 15kv 1250a vcb vacuum circuit breaker

15kv 1250a vcb vacuum circuit breaker:

Full system short circuit current; high mechanical life; electrically operated. Mechanical latching is used because the circuit breaker remains closed during system voltage loss; low short circuit making and breaking energy; control power is used for the operation of the circuit breaker, protective relay and space heater.

Vacuum contactor:

Extremely high mechanical life, can withstand up to 1,000,000 operations and currents up to 630A; purely electrical operation; overload protection using protective relays and short circuit protection using fuses; control power is used for the operation of contactors, protective relays and space heaters.
