It's designed for the 5SP4 distribution board family and mounts on a DIN rail (REG fastening) in any position, occupying 4 modular width units. Supply connects top or bottom. The 100 A rating holds at 40 °C and 45 °C; above that it derates linearly to 80 A at 70 °C. If the panel runs warm — say above 50 °C — you're working with 90 A available, not the full 100. That matters for continuous loads like EV chargers or UPS feeds. Surge current withstand is 1 kA, surge voltage withstand 4 kV. The unit is not adjustable on either trip current or off-delay — it's a straight instantaneous 300 mA AC type. IP20 with distribution board installed — so it's not for wet locations unless the enclosure provides the seal. ## Panel fit That's a 4-MW footprint on a DIN rail — standard for a 2-pole 100 A RCD. The depth is shallow enough that it won't conflict with a 100 mm back-box depth in a typical TP distribution board.","metaTitle":"Siemens 5SM2627-0 SENTRON RCD, 2-pole 100A 300mA AC type","metaDescription":"Siemens 5SM2627-0 SENTRON 2-pole RCD, 100A rated, 300mA AC type, instantaneous.
