It is a 2-pole (2P) unit for AC networks, Type A-SI (Super Immunised) — meaning it handles pulsed DC residual currents and is selectively time-delayed to coordinate with downstream devices, reducing nuisance tripping on transient surges. Rated operational voltage is 220...240 V AC at 50/60 Hz, with an insulation voltage of 500 V AC and impulse withstand of 6 kV. The conditional short-circuit current rating is 10 kA, and the rated breaking/making capacity is Idm 1500 A / Im 1500 A — figures that govern its fault-clearing capability in a distribution board.
Clip-on mounting to DIN rail, 36 mm wide (4 x 9 mm pitches), 73 mm deep, 91 mm tall. Neutral on the left. IP20 finger-safe terminals; IP40 inside a modular enclosure. Pollution degree 3 (industrial environment). The toggle control and contact position indicator give clear visual status. Padlocking provision allows lockout/tagout.
The 8/20 µs impulse withstand of 3000 A per that standard confirms immunity to lightning-induced surges. Electrical durability is 10,000 cycles (AC-1); mechanical durability is 20,000 cycles.
