Operating frequency is 50 Hz only. ## Temperature derating — what the 63 A means in a warm panel The 63 A rating holds at 40 °C ambient; above that, the continuous current must be derated per the manufacturer's table: 58.6 A at 40 °C (already the reference), 56.7 A at 50 °C, 53.55 A at 60 °C, and 50.4 A at 70 °C. In a sealed distribution board with multiple devices side by side, the internal ambient can easily hit 50–60 °C, so the effective capacity is closer to 54–57 A — plan the upstream breaker accordingly. The device occupies 3 modular width units (each 18 mm, so 54 mm of DIN rail) and mounts in any position.","metaTitle":"Siemens SENTRON 5SM2636-6 RCD, 63A 300mA Type A, 3-pole","metaDescription":"Siemens SENTRON 5SM2636-6 RCD unit, 63 A rated at AC, 300 mA residual current, Type A, 3-pole, IP20.
