It carries a continuous rated current of 25 A across the full ambient temperature range from 40 °C to 70 °C, with no derating needed — the rating holds at 25 A all the way up to 70 °C. That's a solid thermal margin for a panel that runs hot.
This MCCB delivers 440 kA interrupting capacity at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V.
That 86 mm depth is the key dimension for panel clearance — it fits standard distribution board depths without sticking out past the gland plate. The width of 140 mm is typical for a 4-pole MCCB in this frame size; check your DIN-rail or mounting-plate layout for the 4-module footprint. It includes a communication function and ground-fault monitoring via summation current formation of L + N conductors, which means you can integrate it into a monitoring system without an external ground-fault relay. The maximum power loss is only 0.5 W, so heat buildup in a sealed enclosure is negligible.
The lifecycle stage is listed as current, meaning Siemens still manufactures this exact order code. No end-of-life notice, no last-time-buy clock.
