This is a Type AC RCCB — it detects sinusoidal alternating residual currents only. For circuits with electronic loads that generate pulsed or DC fault currents (variable-speed drives, LED drivers, UPS systems), a Type A or Type B device would be required. The short-time delayed design (selective or S-type) means it withstands brief surge currents up to 3 kA without nuisance tripping, making it suitable for circuits with high inrush loads or where coordination with downstream RCCBs is needed. Rated IP20 with conductors connected inside the distribution board, so it is intended for enclosed panel use, not exposed outdoor or washdown locations.","metaTitle":"Siemens SENTRON 5SV4344-0LA01 RCCB, 40 A, 30 mA, 4-Pole, DIN","metaDescription":"Siemens SENTRON 5SV4344-0LA01 RCCB, 40 A rated, 30 mA residual, 4-pole, short-time delayed, Type AC.
