That 100 mA threshold is above the 30 mA required for personal shock protection in most residential and light-commercial circuits; this unit is sized for equipment protection or fire-prevention duty where a higher trip threshold avoids nuisance tripping on leakage from filters, VFDs, or long cable runs. ## Derating and thermal reality — the 63 A is a 40 °C number The 63 A rating holds at 40 °C and 45 °C, but it drops stepwise above that: 59.22 A at 50 °C, 55.44 A at 55 °C, 51.66 A at 60 °C, 47.88 A at 65 °C, and 44.1 A at 70 °C. If this RCCB shares a crowded enclosure with other heat sources, the effective capacity is lower than the nameplate — plan the load at the derated figure for the actual ambient. The operating ambient range is -5 to +45 °C, so the 50 °C and above derating curve covers the storage or fault-condition scenario, not normal running. ## Mounting and wiring — DIN rail, 2.5 MW, finger-safe Snaps onto standard DIN rail (REG profile), occupying 2.5 width units (36 mm). The 70 mm depth matches typical modular enclosure back-can depths. ## Sourcing posture — quoted to order Sourced through independent distribution channels. This is a current-production Siemens catalog item, not a surplus or last-time-buy part.","metaTitle":"Siemens 5SM3416-0 RCCB, 63A 100mA 2P Type AC SENTRON","metaDescription":"Siemens 5SM3416-0 SENTRON RCCB, 63A rated current, 100mA residual, 2-pole, Type AC, 230V AC, DIN rail mount.
