Description de Produit

General description

The VACZ1 series AC vacuum contactor is a suitable option for AC tri-phase 50Hz power systems with a rated current of 630 A or below and a rated voltage of 24kv. It is designed for remote circuit making and breaking, frequent starting, and AC motor control. Additionally, it can be combined with a fuse and protector to replace a vacuum circuit breaker. This contactor adheres to the GB/T 14808, IEC 60470, and JB/T 7122 standards, and its main performance indicators meet international standards. The product is known as the High Voltage Vacuum Contactor/Switch for 24kv Capacitor Cabinet and can be found using the keywords Contactor, Vacuum Contactor, or Vacuum Switch. No additional attributes are associated with this product.
