Product details

It's a 4-pole (4P) device rated for distribution applications, with a breaking capacity of 85 kA Icu at 500 V AC (50/60 Hz) per IEC 60947-2.

Magnetic pickup is fixed, not adjustable — so for motor starting or high-inrush loads, confirm the magnetic threshold doesn't nuisance-trip on your load's inrush.

Mounts on a backplate (not DIN rail) — horizontal or vertical orientation, flat against the panel. Front connections on both line and load sides keep wiring accessible. Dimensions: 161 mm H × 140 mm W × 86 mm D. IP40 front face, IK07 impact resistance.

Electrical durability: 20,000 cycles at 440 V at half rated current, 10,000 at full rated current. Mechanical durability: 20,000 cycles. Suitable for isolation per EN/IEC 60947-2 — you can use it as a visible-break disconnect. Neutral protection is set to 1 × Ir (4D). No earth-leakage protection built in.
