That 100 mA sensitivity means it catches earth-leakage faults that could cause fire or equipment damage — it's not a personnel-protection device (those need 30 mA or lower). ## Mounting and integration — DIN rail, 4 MW, any position The 70 mm depth matches standard distribution board cutouts; supply can enter from top or bottom, which simplifies wiring when you're landing cables in a crowded enclosure. ## What the 100 mA trip and Type AC mean for selectivity The 100 mA rated residual operating current is a common choice for sub-distribution boards where you want earth-fault protection but need to coordinate with a 30 mA RCCB upstream (e.g., at the main switch). Type AC means it detects sinusoidal AC residual currents only — not pulsating DC or smooth DC. If your loads include variable-speed drives, UPS systems, or rectifiers that can generate DC fault currents, you'd need a Type A or Type B RCCB instead. The instantaneous design (no short-time delay) means it trips within milliseconds of the fault exceeding 100 mA, which is standard for most distribution applications. ## Temperature range and derating The 63 A rating is confirmed at 40 °C ambient; if your panel runs hotter than that, you'll need to derate per the manufacturer's curve (not provided here, but standard for SENTRON RCCBs). The silicon-free construction is useful for automotive or electronics manufacturing environments where silicone outgassing can contaminate sensitive contacts.","metaTitle":"Siemens 5SV5446-0 SENTRON RCCB, 63 A, 100 mA, 4P","metaDescription":"Siemens 5SV5446-0 SENTRON RCCB, 4-pole, Type AC, 63 A rated, 100 mA trip, 6 kA SCCR, 230/400 V AC.
