JCZ5-7.2/12 Series High Voltage Vacuum Contactor | Efficient 12kV Power Switching

JCZ5-7.2/12 High Voltage Vacuum Contactor

JCZ5-6kv(7.2kv)/10kv(12kv) High Voltage Vacuum Contactor

The series of medium voltage vacuum contactors feature an integrated insulated frame structure, combined with high-quality vacuum interrupters. They offer simple and reliable secondary control, stable performance, and a visually appealing external overall insulated cover. Our company has optimized the transmission mechanism, resulting in a compact structure, good synchronization performance, and minimal bounce. There are three model types available: electromagnetic holding type, mechanical holding type, and permanent magnet holding type, allowing users to select the appropriate operating mechanism based on different applications. Our mechanical holding mechanism is a patented product, providing stable and reliable operation with no mechanical wear, long service life, low switching current, and no power wastage, making it an energy-efficient product.
