It combines a C-curve MCB with a Type AC residual-current device rated at 300 mA. The C characteristic means the magnetic trip fires at 5 to 10 times rated current (160–320 A for this 32 A unit), which handles motor inrush and transformer charging currents without nuisance tripping. The 300 mA Type AC residual detects sinusoidal AC earth faults — standard for general-purpose circuits where DC or pulsed fault currents aren't expected. Neutral conductor switching is built in, so it disconnects both poles when the breaker trips. The 70 mm installation depth matches the typical enclosure depth for residential and light-commercial boards; no extra clearance needed behind the rail. The -40 °C to +75 °C operating range covers unheated utility rooms.","metaTitle":"Siemens 5SU1654-1RC32 SENTRON RCBO 32 A 2-pole C-curve 300 m","metaDescription":"Siemens SENTRON 5SU1654-1RC32 RCBO, 32 A, 2-pole, C characteristic, Type AC, 300 mA residual, 10/15 kA breaking capacity.
