Breaking capacity hits 242 kA at 240 V AC, 187 kA at 415/440 V, 121 kA at 500 V, and 3 kA at 690 V — the 242 kA figure at 240 V means it can interrupt very high fault currents on low-voltage distribution, typical for large transformer-fed switchboards.
Footprint is 105 mm wide × 181 mm high × 86 mm deep — the 86 mm depth (3.39 in) is the projection behind the panel face, so check gland-plate clearance in shallow enclosures.
242 kA at 240 V AC, which covers high-fault-current applications like transformer secondaries or large busway feeds.
