The 30 mA rating covers personnel protection (direct contact) per IEC/EN 61008. ## Thermal derating and panel loading The 63 A rating holds at 40 °C (58.6 A at 40 °C is the continuous current limit in a hot state). Derate progressively: 56.7 A at 50 °C, 53.55 A at 60 °C, 50.4 A at 70 °C. Each pole dissipates 4.6 W at rated current, so a 2-pole unit adds 9.2 W of heat to the cabinet; factor that into your thermal budget. Two modular width units (MW) on DIN rail, 70 mm installation depth. IP20 with connected conductors in an installed distribution board — not rated for wet or dusty environments. The design is not sealable, so no padlock provision. Surge current resistance 3 kA, surge voltage resistance 4 kV. Rated frequency 50 Hz AC only.","metaTitle":"Siemens SENTRON 5SM2325-3 RCD Unit, 2-Pole, 63 A, 30 mA, Typ","metaDescription":"Siemens SENTRON 5SM2325-3 2-pole RCD unit, 63 A rated current, 30 mA Type F, short-time delayed.
