Rated 63 A continuously at 40 °C ambient, with minimal thermal derating up to 70 °C (58 A at 70 °C), so it holds its full rating across typical panel internal temperatures without oversizing. Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — high enough for most industrial service-entrance applications where fault current is substantial; the 11.9 kA at 690 V still covers the majority of 690 V distribution systems.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling the backplate.
Rated insulation voltage 800 V means it can be used in 690 V systems without de-rating the dielectric clearance — common in mining, marine, and heavy industrial installations. Maximum power loss 19.8 W per pole — three poles total under 60 W — so ventilation in a sealed enclosure is manageable; no forced cooling required for most panel layouts.
