That matters in a distribution board feeding multiple circuits where nuisance tripping costs production time. At 40 °C ambient the continuous current rating derates to 58.6 A; at 50 °C it drops to 56.7 A, and at 70 °C it's 50.4 A. The insulation voltage (Ui) is 460 V, so it's fine on 400/415 V three-phase networks common in industrial and commercial distribution. Surge current resistance is rated 5 kA, surge voltage resistance 4 kV — that covers most utility-side transients on a TN or TT system without external surge protection, though a coordinated SPD upstream is still good practice for sensitive electronics on the load side. Operating frequency is 50/60 Hz, so it's at home on either mains standard. Occupies 3 modular-width units (each 18 mm) on a DIN rail — that's 54 mm of rail space. Depth is 70 mm, so it clears a standard 80 mm deep enclosure without the door hitting the conductors.","metaTitle":"Siemens 5SM2635-8 SENTRON RCD Unit, 63 A, 300 mA, Type A, 3-","metaDescription":"Siemens 5SM2635-8 SENTRON selective RCD unit, 63 A rated, 300 mA Type A, 3-pole, IP20, -40 to 75 °C.
