This is an instantaneous-trip device — no intentional time delay — so it responds immediately to earth faults, which makes it a fit for general-purpose socket-outlet and lighting circuits in residential and commercial distribution boards where nuisance tripping from transient surges is not expected. That is the standard choice for basic shock and fire protection in circuits without electronic loads that generate pulsed or high-frequency DC fault currents. For VFDs, UPS systems, or EV chargers, a Type A or Type B RCCB would be needed — this Type AC unit is not suitable there. The 60 mm grid spacing aligns with standard distribution board cut-outs. Depth is 70 mm, matching the installation depth, so it sits flush with other SENTRON 4-MW devices in the same row. Supply can feed from top or bottom. Rated conditional short-circuit current per IEC 61008-1 is 0.8 kA, backed by a maximum permissible series fuse of 80 A. The 10 kA SCCR applies when the RCCB is coordinated with an upstream overcurrent protective device — typically a 63 A or 80 A MCB or fuse. Without that coordination, the 0.8 kA value governs. Power loss is 2 W per pole in hot operating state. Silicon-free construction is noted — relevant for certain automotive or high-reliability coating processes where silicone outgassing must be avoided.","metaTitle":"Siemens SENTRON 5SV4644-0 RCCB, 4-pole, 40 A, 300 mA, Type A","metaDescription":"Siemens SENTRON 5SV4644-0 RCCB, 4-pole, 40 A, 300 mA, Type AC, 230/400 V, 10 kA SCCR, DIN rail mount.
