It protects a single-phase final subcircuit against overload, short-circuit, and earth leakage in one unit, saving a DIN-rail position compared to separate MCB + RCCB. Rated 25 A at 30 °C ambient with a Type C tripping characteristic (magnetic release between 5× and 10× In), it handles motor-starting inrush and moderate inductive loads on 230/240 V 50 Hz supplies. At 40 °C the continuous rating drops to 23.5 A, at 50 °C to 21.75 A, and at 70 °C to 18.25 A.
Rated impulse withstand voltage is 4 kV, insulation voltage 264 V. The manufacturer provides the standard declaration of conformity (CE, UKCA) and the product is designed to EN 60898 and IEC 60947-2. No specific UL or CSA listing is on record for this order code.
