The instantaneous design (no short-time delay,) means it trips within the standard RCCB response window — no intentional delay for coordination with surge arrestors or downstream devices. The 63 A continuous rating holds at 40 °C and 45 °C without derating; at 50 °C it drops to 60.48 A, at 55 °C to 57.96 A, and at 60 °C to 55.44 A (–). If the panel ambient inside the enclosure runs above 45 °C, size the upstream overcurrent device accordingly — the RCCB itself is not a current-limiting device and relies on an MCB or fuse for overcurrent protection. The 10 kA short-circuit current rating is the withstand capacity; downstream coordination per EN 60898 yields 0.8 kA, and per IEC 61008-1 also 0.8 kA. Snap-on DIN rail mounting in any orientation. Occupies 4 modular width units. Installation depth is 55 mm. IP20 with connected conductors and distribution board installed. Finger and back-of-hand safe touch protection. Silicon-free construction.","metaTitle":"Siemens 5SM1356-6 SENTRON RCCB, 4P, 63A, 30mA, Type A","metaDescription":"Siemens 5SM1356-6 SENTRON RCCB, 4-pole, 63 A rated, 30 mA trip, Type A, 10 kA SCCR, IP20, DIN rail mount.
