3AV5-12/1250-31.5 Indoor High-voltage Vacuum Circuit Breaker

3AV5 series indoor AC high-voltage vacuum circuit breaker is an indoor switching equipment with three-phase AC 50HZ and rated voltage 12KV. There are three kinds, withdrawable type, stationary type and side-mounted type.

3AV5-12 indoor high-voltage vacuum circuit breaker adopts solid sealing insulation technology of ABB and SIEMENS. The vacuum arc extinguishing chamber and other parts of the primary circuit are sealed with epoxy resin material to form high insulation and high mechanical strength pole, which avoids the influence of harsh operating environment on the outer insulation of the primary circuit and realizes complete maintenance-free. Optimized spring operation mechanism, simple structure, stable performance, for industrial and mining enterprises, power plants and substations as electrical equipment control and protection, and suitable for frequent operation places.

3AV5 type side mounted vacuum circuit breaker adopts fixed installation, mainly used for fixed switchgear, such as ring network cabinet, box type substation or various non-standard power supply system. The main loop adopts solid sealing pole, miniaturized operation panel, and saves space in the cabinet.
