Vacuum switching that outlasts the load
CBX, CLX, and CPX deliver robust MV switching up to 12 kV with fast action, long life, and zero-compromise reliability for motors, transformers, and capacitor banks.
Explore MoreAging contactors fail where it hurts — the first switch.
Slow closures, worn mechanisms, weak interlocks, and high-maintenance switching raise risk. They strain motors, trip feeders, and stall production.
Meet the VCU family — built for heavy-duty MV switching
The CBX, CLX, and CPX series give you fast, reliable vacuum switching for motors, transformers, capacitors, and feeders up to 12 kV. CBX delivers fixed-type strength with up to one million operations. CLX adds fuse-ready designs and retrofit-friendly layouts. CPX brings withdrawable convenience for quick maintenance and safer panel handling. With high-endurance interrupters, rugged mechanisms, and full auxiliary options, this range fits every industrial MV need.
