Type AC detection responds to sinusoidal AC fault currents. For circuits with pulsating DC leakage, use Type A or Type F. 100 mA sensitivity suits circuits with expected equipment earth leakage. The C characteristic has a magnetic trip threshold of 5 to 10 times the rated current (200–400 A instantaneous trip for this 40 A unit), intended for circuits with moderate inrush — motor-starting, banks of fluorescent lighting, small transformers. The 4-module width (72 mm) and 70 mm depth fit standard SENTRON distribution boards and enclosures. Supply can enter from either top or bottom. The IP20 rating applies with conductors connected inside an installed distribution board — not suitable for wet or dusty locations without an outer enclosure. Mounting position is unrestricted. The EN 60898 value is the one used for coordination in residential and commercial final circuits per the standard's scope. The IEC 60947-2 rating applies when the device is deployed in an industrial context where the standard's more demanding performance criteria (including I²t let-through and operating sequence) are specified. For selectivity with an upstream SENTRON fuse or MCCB, the 15 kA figure provides additional headroom in the fault-current withstand calculation at the distribution board.","metaTitle":"Siemens 5SU1424-1RC40 SENTRON RCBO 40A 2P C-Char 100mA AC Ty","metaDescription":"Siemens SENTRON 5SU1424-1RC40 RCBO, 40 A, 2-pole, C characteristic, 100 mA AC residual current, 10 kA (EN 60898) / 15 kA (IEC 60947-2) breaking capacity.
