It detects Type A fault currents — sinusoidal AC and pulsating DC — and trips instantaneously (no short-time delay). Per the datasheet, the I²t withstand is 70 000 A²·s, and surge current resistance is rated 1 kA. Mounts on DIN rail (REG profile), occupies 4 width units (36 mm), and accepts top or bottom supply feed. The housing is IP20 with conductors connected — suitable for enclosed distribution boards. Installation depth is 70 mm. At 50 °C the rating drops to 60.48 A, at 55 °C to 57.96 A, at 60 °C to 55.44 A, at 65 °C to 52.92 A, and at 70 °C to 50.4 A. Mounting position is any orientation. DIN-rail snap-on, 36 mm width (4 TE). Depth of 70 mm fits standard enclosures with clearance for gland plates. Silicon-free construction per the product feature. Finger and back-of-hand safe protection against electrical shock.","metaTitle":"Siemens SENTRON 5SM3656-6 RCCB, 63 A, 4-pole, Type A, 10 kA","metaDescription":"Siemens SENTRON 5SM3656-6 RCCB, 63 A rated, 4-pole, Type A, 10 kA SCCR, instantaneous, DIN rail mount.
