Rated short-circuit current withstand is 10 kA, and the unit is instantaneous (no short-time delay), so it trips immediately on residual fault — standard for personnel protection in final subcircuits. Mounts on DIN rail (REG profile), occupies 4 width units (approx 72 mm). Installation depth is 55 mm. Any mounting position is permitted. Tightening torque is 2.5 to 3 N·m with screw-type terminals. Supply connection can be top or bottom — no polarity restriction on this RCCB design. The unit is silicone-free, which matters for applications where silicone outgassing can contaminate contacts or optical surfaces. Overvoltage category III, pollution degree typical for distribution boards. The design family is 5SM1.","metaTitle":"Siemens 5SM1347-6 SENTRON RCCB, 80 A 30 mA 4P Type A","metaDescription":"Siemens 5SM1347-6 SENTRON RCCB, 4-pole, 80 A rated current, 30 mA trip, Type A, 10 kA SCCR, 400 V AC, DIN rail.
