Snaps onto DIN rail (REG) and occupies 4 modular width units at 60 mm grid spacing — 72 mm wide, 90 mm tall, 70 mm installation depth. The supply can land top or bottom; for the SIGRES function, power stays present at the top terminals even when the device is switched off. IP20 with connected conductors, so it lives inside a distribution board, not exposed to washdown. Silicon-free construction, which matters if this panel shares air with potting or coating lines.","metaTitle":"Siemens 5SV3644-4 SENTRON RCCB, Type B, 40A 300mA, 4-pole","metaDescription":"Siemens 5SV3644-4 SENTRON RCCB, 4-pole Type B short-time delayed, 40A/300mA, 400V AC, 10kA SCCR.
