The 300 mA sensitivity suits circuits where a lower 30 mA threshold would cause nuisance tripping — typically socket-outlet groups feeding fixed equipment or distribution sub-mains where earth-leakage is expected but must still be interrupted. ## Ratings in Context The 63 A rating covers the full load current of a typical 3-bedroom distribution board or a small commercial sub-main. The 300 mA residual sensitivity is the standard choice for fire-prevention protection on circuits supplying fixed equipment (water heaters, air-conditioning units, pumps) where a 30 mA RCD would trip on normal leakage from heating elements or motor windings. The 2.5 MW power-loss figure (at rated load) is the thermal dissipation the device sheds into the enclosure. In a populated distribution board, that heat must be factored into the panel's thermal budget — particularly if the RCBO is mounted alongside other high-current devices in a confined DIN-rail enclosure without forced ventilation.","metaTitle":"5SM3616-0MJ Siemens RCBO 63A 10kA 300mA 1+N-Pol","metaDescription":"Siemens 5SM3616-0MJ residual current operated circuit breaker, 63A, 10kA, 300mA, 1+N-Pol, 230V.
