This is a 1P+N unit rated at 25 A with 300 mA sensitivity, Type AC, instantaneous trip, voltage-independent — meaning it trips on residual current regardless of whether the supply voltage is present. The 25 A rated current and 300 mA sensitivity define the load and protection threshold. At 230 V AC phase-to-neutral, this block protects a single-phase branch circuit. Voltage-independent trip is a reliability advantage: the RCD will still trip on a residual fault even if the neutral is lost or voltage drops. Instantaneous trip means no intentional time delay — it reacts to the first fault cycle, which is standard for personnel protection (though 300 mA is too high for direct personal protection; it serves as equipment/fire protection). ## Installation & Environment Clip-on mounting to DIN rail. The block occupies 2 x 9 mm pitches — 18 mm wide. Neutral is on the left. Terminals accept cable upstream: rigid 0.75…16 mm², flexible 0.33…10 mm². Tightening torque 2 N·m, strip length 13 mm. Ambient operation -5…60 °C, storage -40…60 °C, 95% RH at 55 °C, operating altitude up to 2000 m. Rated insulation voltage 400 V AC, impulse withstand 6 kV — both per EN 61009-1. Listed standards: IEC 60947-2, EN 61009-1, EN 61009-2-1. Local ON/OFF indication. The evidence does not list UL, CSA, RoHS, or REACH documentation specifically for this order code; compliance documentation would need to be verified against the manufacturer's original technical file.","metaTitle":"A9N21481 Vigi TG40 25A 300mA RCD Add-on Block, Obsolete","metaDescription":"A9N21481 Prodis Vigi TG40 add-on RCD, 1P+N 25A 300mA Type AC.
