Rated operating range
It integrates a 25 A B-curve miniature circuit breaker with a 300 mA residual-current device into a single 1+N-pole module.
Deployment context
The 70 mm depth fits standard DIN-rail enclosures used in final-distribution sub-boards. Type A sensitivity detects pulsating DC residual currents in addition to sinusoidal AC — relevant for circuits feeding single-phase rectified loads such as washing machines, LED drivers, or EV chargers where Type AC devices would be blind to the fault signature.
