Product details

It delivers 100 kA Icu at 500 V DC (two poles in series) per EN/IEC 60947-2, making it a fit for high-fault DC distribution in industrial DC bus or battery-string applications where fault currents can exceed 50 kA.

Rated insulation voltage is 750 V DC, so the breaker can be used in 500 V DC systems with headroom.

Fixed backplate mount, 4-pole, 185 mm wide × 255 mm tall × 110 mm deep. Front connections both top and bottom — no rear-access requirement, which simplifies panel layout. Toggle control. Suitable for horizontal or vertical mounting flat on the back. IP40 finger-safe front; IK07 impact resistance.
