Looks like a small switch, but is a compact circuit breaker for various types of equipment protection. The CBI B-Frame 0.1-30A for AC and DC applications from Emcomp International AB is ideal for space-saving installations. Elevated ambient temperatures are not a problem because the circuit breaker does not contain a bi-metal element.
Instead, the trip sequence is based on the hydraulic-magnetic principle, which eliminates temperature coefficients: The breaker operates reliably in a temperature range of -40ºC to + 85ºC. In addition to more precise tripping, the technology also promises significant space savings, reduces energy consumption and increases the service life of the application.
The B-Frame has a modular design: In addition to options such as rated current and time delay, handle, terminals, color, imprint, auxiliary switch, trip alarm switch, etc. can be combined in a modular fashion. The rocker can also be supplied with lighting. The CBI B-Frame series can be built in single and double pole configurations and is IEC/EN 60934 approved. On the UL side, they are available as UL recognized (UL1077) and UL listed to UL489A. B-frame also has CCC approval for the Chinese market.
