Three poles, rated 25 A continuous at 40 °C, and it holds that same 25 A rating all the way up to 50 °C before it starts to derate (24 A at 55 °C, 23 A at 70 °C). That thermal stability matters if this breaker lands in a warm panel or near other heat sources.
Breaking capacity — where this thing earns its keep
That's a massive interrupting rating for a 25 A frame — it's designed for high-fault locations like a service entrance or a large transformer secondary where available fault current is brutal. At 415 V it still handles 121 kA, at 440 V it's 75.6 kA, and it stays at 17 kA through 500 V and 690 V. For a 25 A MCCB, that's serious headroom; you're not going to run out of SCCR on a typical industrial panel.
What's built into this variant
That's enough feedback for a PLC to know the breaker position and whether it tripped on fault versus being opened manually. It also has a voltage trip indicator — a mechanical flag that stays latched after a trip so you can walk the panel and see which breaker opened. It's a pure line-protection MCCB with remote trip capability and status contacts.
Maximum power loss is 8.5 W — negligible for panel heat calculations, but factor it in if you're stuffing a dozen of these in a sealed enclosure.
