The 300 mA trip threshold makes it suitable for general fault protection rather than personal shock protection (which typically uses 30 mA). The Type A designation means it detects sinusoidal AC residual currents plus pulsating DC residual currents up to 6 mA — common for circuits with single-phase rectifiers, switching power supplies, or variable-speed drives. Mounts on a DIN rail (REG profile) and occupies 4 width units (72 mm) in the enclosure. Supply can enter from top or bottom, which simplifies panel layout. No short-time delay on the trip; it's an instantaneous RCCB, so nuisance tripping from transient surge currents (rated surge withstand is 1 kA) is possible on circuits with heavy switching loads.","metaTitle":"Siemens 5SV3644-6XX01 SENTRON RCCB, 40 A, 300 mA, Type A, 4-","metaDescription":"Siemens 5SV3644-6XX01 SENTRON RCCB, 40 A rated at 40 °C, 300 mA Type A trip, 4-pole, 10 kA SCCR, 230/400 V AC.
