That 500 A holds flat through 50 °C — only drops to 495 A at 55 °C and 480 A at 70 °C, so it doesn't derate hard in a warm panel. Interrupting capacity at 240 V is 187 kA; at 415 V and 440 V it's 121 kA; at 500 V it's 75.6 kA; at 690 V it's 9 kA.
Depth of 110 mm includes the handle and terminals; leave clearance for cable bending radius and the UVR coil projection on the left side.
Time-current characteristics
The short-time withstand rating is 6 kA limited to 1 s — that's the thermal let-through the breaker can handle during a delayed trip coordination interval. The trip unit's minimum response time is 4 s, maximum 13 s, which puts it in the 'selective' band for downstream coordination with smaller MCCBs or fused switches.
Environmental limits
The storage low end matters if this sits in an unheated warehouse before installation — it's fine down to -40 °C, but don't energize below -25 °C.
