It's a 4-pole unit with a 36 kA Icu breaking capacity at 440 V AC 50/60 Hz, compliant with IEC 60947-2. The fixed-mount design with front connections and a 45 mm pole pitch makes it a straightforward panel fit for distribution applications.
At 380 V AC and 400/415 V AC it holds the same 36 kA rating, and at 220/230 V AC it steps up to 40 kA Icu. For a 630 A frame, that gives you decent selectivity headroom downstream of a higher-rated upstream device, especially in 400 V distribution panels.
The TM-D thermal-magnetic trip unit is rated 500 A at 50 °C, with a fixed magnetic trip threshold of 5000 A. That's a standard fixed-trip thermal-magnetic — no interchangeable rating plugs or electronic adjustments.
Physical integration
Fixed mounting on a backplate, front connections both top and bottom. The 185 mm width, 255 mm height, and 140 mm depth give you the envelope for panel layout. IP20 finger-safe protection on the front, IK07 impact resistance. The toggle control and positive contact indication give a clear visual on breaker status. No earth-leakage protection module on this variant.
