The 300 mA threshold is a fire-protection level, not personnel protection (that's 30 mA); it's typically used on submain or feeder circuits where a lower trip would cause nuisance tripping from leakage in long cable runs or multiple loads. Rated 63 A at AC, but the current derates with ambient temperature: 58.6 A at 40 °C, 56.7 A at 50 °C, 53.55 A at 60 °C, and 50.4 A at 70 °C. Surge current resistance 1 kA, surge voltage resistance 4000 V. IP20 with the distribution board installed and conductors connected. That's touch-finger protection on the front, but no water ingress protection — mount inside an enclosure, not in a wet location. Mounts on DIN rail (REG fastening method), any position. 2 modular width units (71 mm wide) — fits standard 18 mm-per-module spacing. Depth 70 mm, height 90 mm. Not sealable (no padlockable toggle). Rated fault current is fixed at 300 mA — not adjustable. No OFF-delay adjustment either; it's instantaneous, so it trips within one AC cycle on a solid fault. That means no selectivity with downstream 30 mA RCDs on the same circuit unless the downstream device has a short time delay.","metaTitle":"Siemens 5SM2625-6 SENTRON RCD, 2-pole 63A Type A 300mA","metaDescription":"Siemens 5SM2625-6 SENTRON RCD unit, 2-pole, 63 A rated, Type A, 300 mA fault current.

It will not drop into a panel wired for the 5SM2625-6 without checking the busbar and terminal layout; the modular width and DIN-rail footprint are the same, but the connection scheme may differ. Verify the wiring diagram before swapping."},{"question":"Where can I buy 5SM2625-6?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
