It carries a continuous current rating of 160 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel layout when the breaker sits near other heat sources. Rated interrupting capacity hits 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault scenarios common in industrial main feeders without cascading upstream. At 690 V the rating drops to 3.7 kA — that's the limit for that voltage class; don't spec it for 690 V distribution unless the available fault current is well below that figure.
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The 86 mm depth leaves room behind the door for wiring gutters and auxiliary wiring.
