That 30 mA type A rating means it catches pulsating DC fault currents on top of sinusoidal AC — common downstream of single-phase rectifiers in VFDs, switched-mode supplies, or lighting ballasts. The short-time delay prevents nuisance tripping from transient surge currents that would otherwise take out a standard instantaneous RCD. Full 63 A rating holds up to 45 °C ambient — at 40 °C and 45 °C it carries 58.59 A continuous. Above that it derates: 56.7 A at 50 °C, 54.81 A at 55 °C, 53.55 A at 60 °C, 52.29 A at 65 °C, and 50.4 A at 70 °C. The 2-pole form factor snaps onto standard DIN rail; no neutral switching on this variant since it's a 2-pole RC unit, not an RCBO.","metaTitle":"Siemens 5SM9325-6KK01 SENTRON RC Unit, 63 A, 30 mA, 2-Pole","metaDescription":"Siemens SENTRON 5SM9325-6KK01 RC unit electronic, 2-pole, type A, short-time delayed, 63 A, 30 mA, 400 V AC.
