Its interrupting capacity hits 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, and 187 kA at 500 V — at 690 V it still clears 3.7 kA.
Sizing and thermal performance across the panel ambient range
That's useful for a panel packed with drives or transformers that push internal temperatures. The adjustable thermal-magnetic trip range spans 150 A to 1200 A (minimum to maximum), with the full-scale value at 100 A and initial value at 20 A, so it can be tuned to protect a specific downstream load rather than just the bus. Power loss maxes at 10 W, which is modest for a 4-pole frame — keeps heat load low in a sealed enclosure. Dimensions are 181 mm high, 140 mm wide, 86 mm deep; the 140 mm width is standard for a 4-pole MCCB footprint, so it drops into existing SENTRON panel layouts without re-drilling the mounting plate.
Environmental and storage tolerances
That -40 °C storage floor matters for cold-chain or unheated warehouse staging — the breaker won't suffer damage sitting in a sub-zero shipping container before installation. The operating low end at -25 °C covers most outdoor panel applications in temperate climates.
