The interrupting rating hits 330 kA at 240 V, 242 kA at 415 V, and 187 kA at 500 V, with a sharp drop to 3 kA at 690 V. That 330 kA figure at 240 V places it in the high-fault tier for industrial main or feeder duty where available short-circuit current is extreme.
Ratings and release
The overcurrent release is an ETU350 — an electronic trip unit with adjustable functions typical for selective coordination in industrial distribution. Power loss is a modest 3 W maximum.
Integration dimensions
The width is the critical fit dimension for multi-breaker panelboards — 105 mm is a standard 4-module footprint on most DIN-rail or busbar systems. Depth of 86 mm leaves clearance for rear-connected bus stabs or cable lugs in a typical 200 mm deep enclosure.
