It's designed for DIN-rail mounting in distribution boards, occupying 4 modular width units (72 mm) with a 70 mm installation depth. Supply voltage range is 70–440 V AC at 50/60 Hz, covering most standard low-voltage networks in commercial and industrial panels. ## Where you'll find this in a panel The short-time delayed design (SIGRES function) lets you feed supply from top or bottom, even with the switch off, which simplifies busbar routing in multi-row boards. Ambient temperature range is -25 °C to +45 °C during operation, with storage down to -40 °C — fine for unheated utility rooms or outdoor enclosures in moderate climates. The 5SV3642-4KK14 carries silicon-free construction, which matters for applications like automotive paint lines or semiconductor fabs where silicone outgassing can ruin coatings or optics.","metaTitle":"Siemens 5SV3642-4KK14 SENTRON RCCB, 25 A, 300 mA, Type B+","metaDescription":"Siemens 5SV3642-4KK14 SENTRON RCCB, 4-pole, Type B+, short-time delayed, 25 A, 300 mA, 400 V AC, 10 kA SCCR.
