CBM3000 circuit breaker manager (CBM) is an integrated control relay, designed for 3KV to 35KV indoor switchgear, used to replace multiple components in LV compartments, and can reduce LV panel space occupation. It can be called a switchgear circuit breaker too.
On its panel, this switchgear breaker provides a primary circuit simulation diagram, switch indicator, VCB status & control switch, environment control, high voltage indicator, etc. The special sound prompt function can remind staff to operate the switchgear safely.
This switchgear circuit breaker can be used in various types of switchgear such as GZS (Centrally Installed Switchgear), Handcart Cabinet, Fixed Cabinets, Ring Main Units, etc.
