Product details

Rated 125 A with 30 mA sensitivity, it provides instantaneous Type A-SI (Super Immunised) protection against sinusoidal AC and pulsating DC earth faults, plus high immunity to nuisance tripping from transient surges or harmonic-rich loads. That 30 mA threshold is the standard for personal shock protection in most residential, commercial, and light industrial final circuits.

The 4P (four-pole) block occupies 10 x 9 mm pitches (90 mm of rail width) and connects to the upstream MCB by screws through tunnel-type terminals accepting 1–50 mm² rigid or 1–35 mm² flexible conductors.

Rated operational voltage is 400–415 V AC at 50 Hz; insulation voltage 500 V AC; impulse withstand 6 kV per IEC 60947-2. Pollution degree 3 (conductive or dry non-conductive pollution — typical for industrial control panels). Complies with EN 61009 and IEC/EN 61009-2-1.
