The interrupting ratings are substantial: 154 kA at 415 V, 220 kA at 240 V, and still 17 kA at 690 V, which gives solid SCCR headroom for most industrial distribution panels without needing a current-limiting fuse upstream.
Interrupting and thermal performance
The thermal derating curve is flat up to 50 °C (still 63 A), then drops only 2 A by 55 °C and 5 A by 70 °C, meaning the breaker runs cool in a warm panel. Power loss maxes at 17.3 W, which is manageable for enclosure heat calculations.
Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON or third-party distribution blocks without panel rework. Front IP40 protection means it's fine for enclosed panels but not washdown environments.
