3.Product Feature And Application
630A Vacuum interrupter for contactor:
Size - vacuum interrupters are smaller, so they require less space.
Safety - the unique design of vacuum interrupter has considerable safety advantages compared with other types.
Environmental protection - vacuum interrupters are made of materials that do not pose a threat to our environment.
4.Product Details
Vacuum contactor uses vacuum as arc extinguishing medium and is designed to frequently connect and disconnect normal working current. Our vacuum contactors are widely used in demanding applications and can work at low and medium voltage to achieve frequent switching operation. As your leading manufacturer of vacuum contactors, we purchase vacuum interrupters from reliable suppliers to provide excellent fire extinguishing performance. By following strict manufacturing procedures and quality system, we ensure the quality of our vacuum contactors without compromise.630A Vacuum interrupter for contactor
