Key features

Advanced Vacuum Arc Extinguishing: Seals electrical arcs inside the interrupter chamber to prevent external fire risks and deliver zero-flashover safety during heavy load operations.

Zero Wear Arcing Contacts: Stop replacing burned contact tips; high-grade vacuum bottles prevent oxidation and contact erosion to cut equipment downtime by over 80%.

1 Million Cycles Electrical Life: Engineered for continuous 1.14kV/400A operations, delivering 1,000,000 electrical duty cycles for ultra-reliable, maintenance-free performance.

Heavy-Duty Industrial Switching: Perfect for mining, metallurgical plants, and power distribution systems where frequent motor starting and capacitor switching are required.

Superior Compact & Quiet Design: Provides 30% higher breaking capacity and quieter operation than traditional air contactors, taking up significantly less cabinet space.

Product Q&A

Q:What is the primary application of the CKJ5-1.14KV/400A AC Vacuum Contactor?

The CKJ5-1.14KV/400A AC vacuum contactor is designed for primary circuit control in AC 50Hz/60Hz power systems with rated operating voltage up to 1.14kV and rated current up to 400A. It is engineered for frequent remote making and breaking of electrical loads, heavy-duty industrial motor starting, power transformer control, and reactive power compensation in power grids, mining operations, and metallurgical plants.

Q:What are the main benefits of using a vacuum contactor over a traditional air contactor?

Vacuum contactors quench arcs inside sealed interrupters, eliminating external flashover risks. Sealed contacts prevent oxidation and wear, extending electrical life to 1,000,000 cycles while reducing maintenance. Compact physical dimensions also save vital switchgear panel space.

Q:Can the control coil voltage and auxiliary contact configuration be customized?

Yes, the operating coil control voltage can be customized for standard AC or DC power supplies including 110V, 220V, and 380V according to system design requirements. Auxiliary contact blocks are also configurable in standard 2NO+2NC or 4NO+4NC combinations to match specific control circuit signaling and interlocking requirements.
