The Siemens 5SV3445-6 is a 4-pole residual current circuit breaker (RCCB) in the 5SV3 family, rated 125 A with a 100 mA trip sensitivity, Type A, for 400 V AC systems. Type A detection means it responds to sinusoidal AC residual currents and pulsed DC residual currents up to 6 mA smooth DC — the standard choice for circuits with single-phase rectifiers, switched-mode power supplies, or variable-speed drives that can generate pulsating DC fault currents. The 100 mA sensitivity suits sub-distribution or feeder protection where nuisance tripping from leakage on long cable runs or equipment filters must be avoided, while still providing earth-fault protection for personnel and equipment.
