It is a 3-pole, type A instantaneous RCD rated at 63 A with a 300 mA residual tripping current, operating on a 230/400 V AC supply at 50 Hz. This is the electronic variant — the DI unit, type A, covering the 0.3...63 A range in a 3-pole, 300 mA configuration. The 63 A rated current at AC and 300 mA residual current define the load and protection envelope: this unit handles circuits up to 63 A and trips on ground faults above 300 mA. The 3 kA surge current resistance tells you it can withstand transient overvoltages without nuisance tripping, which matters on lines with motor starts or capacitor switching. Occupies 3 width units, so at 54 mm wide it fits a standard 3-module slot. Depth is 70 mm, installation depth the same, height 100 mm. Mounting position is any, which gives flexibility in tight enclosures. The supply connects at the top, above the miniature circuit breaker. Terminal accepts solid conductors from 0.75 to 35 mm² and stranded from 0.75 to 25 mm²; tighten to 2.5...3 N·m. Designed to DIN EN 61346-2 and DIN EN 81346-2 (function designation F). Overvoltage category III per IEC. The product is silicon-free. The unit is the electronic RC companion for the 5SL4 MCB series — it is not a standalone RCCB; it mounts mechanically and electrically to the 5SL4 breaker. The 5SM9 design designation identifies this as the second-generation RC unit platform.","metaTitle":"Siemens 5SM9636-6 SENTRON RC Unit, 3P, Type A, 63 A, 300 mA","metaDescription":"Siemens 5SM9636-6 SENTRON RC unit for 5SL4, 3-pole, type A, 63 A rated current, 300 mA residual current, 230/400 V AC.
