Product details

Breaking capacity — the number that decides fault protection

Rated 100 kA at 400 V AC, 500 V AC, and 690 V AC, this breaker can safely interrupt a fault current up to 100,000 amps at those voltages without welding contacts or cascading failure upstream. At 240 V AC the breaking capacity is also 100 kA, so the same rating holds across the common low-voltage supply levels.

Size S00 — 45 mm wide, 97 mm deep, 106 mm tall — keeps the footprint compact for a 100 kA device. The screwdriver shaft diameter is 3 mm for the terminal screws.
