Miniature Circuit Breaker Screw Connection 2Poles B-Characteristic 40A 10kA 400V IP20 Hager

Description

Mini circuit breaker (formerly miniature circuit breaker) 2-pole with screw connection NBN240 40A, B-characteristic with a breaking capacity of 10kA. Double connection for power supply, one for phase busbar and one for cables. This provides a safe connection. Provides reliable and safe protection of cables/lines against overload and short circuit. MCB (Mini Circuit Breaker) is referred to in older regulations as miniature circuit breaker/automatic fuse.
