The System 55 FLEX stove group is quick and easy to install in System 55 FLEX cabinets. In addition, this circuit breaker (stove group) is also suitable for use in Medusa FLEX cabinets. The installation time of System 55 circuit breakers is minimal because the DIN modular components are simply snapped on and the wiring is already optimally matched to the group boxes. Includes jumper combs on the feeding side. Eaton Holec System 55 FLEX circuit breakers are available in several variants.
