other circuit breakers and accessories
In addition to an extensive portfolio of front-panel and DIN rail mounted hydraulic-magnetic circuit breakers, CBI manufactures other types of protective elements including the necessary accessories. Our specialists will be happy to help you choose the right solution.
CBI-electric has gradually established itself as a supplier of hydraulic-magnetic circuit breakers in marginal markets around the world. The roots of this manufacturer go back to 1949.
residual current circuit breaker (RCBO)
The RCBO (Residual Current Circuit Breaker with Overcurrent protection) is a combination of a residual current device and a hydraulic-magnetic circuit breaker. It is increasingly common to design installations with individual leakage current detection in each circuit. This is a way to eliminate the risk of a complete failure if there is a leak in only one circuit.
properties
- AC circuit breaker and residual current device
- design 1P
- rated current 1 – 63 A
- short-circuit resistance up to 6 kA
- CE approval, UL 1053, EAC
- operating temperature -40 to +85 °C

moulded case circuit breakers (MCCBs)
CBI’s moulded case circuit breakers (MCCBs) are specialised hydraulic-magnetic circuit breakers providing enhanced mechanical protection. They have a moulded case that helps protect the internal components from damage in harsh conditions.
properties
- AC and DC circuit breakers
- rated current 20 – 1500 A
- short-circuit resistance up to 40 kA
- CE approval, UL 489A
- robust design
- working temperature -40°C to +85°C
