The 10 kA breaking capacity per EN 60898 (20 kA per IEC 60947-2) means it can safely clear a bolted fault on a 230/240 V, 50 Hz supply without upstream damage.
At 40 °C it derates to 18.8 A, at 50 °C to 17.4 A, and at 70 °C to 14.6 A. The 2 MW width (36 mm) leaves room for adjacent breakers in a crowded DIN rail; mounting position is unrestricted, and the supply can enter from top or bottom, which simplifies busbar layout.
It is a 1P+N RCBO rated 20 A at 30 °C with a C tripping characteristic, 10 kA breaking capacity per EN 60898 and 20 kA per IEC 60947-2, for 230/240 V, 50 Hz supplies.
This RCBO is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
It measures 36 mm wide (2 MW), 90 mm high, and 77 mm deep, with an installation depth of 70 mm.
