It carries a 25 A continuous rating at 40 °C, holds that rating through 50 °C, then derates slightly to 23 A at 70 °C — so in a warm enclosure you lose only about 8 % of headroom.
This MCCB delivers 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — those are the interrupting ratings you need for selective coordination studies.
The MCCB measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that mounts on a DIN rail or panel-mount adapter. The shunt trip release occupies one auxiliary slot; the design also accommodates two auxiliary switches (HQ type). Max power loss is 8.5 W, so ventilation in a sealed enclosure is not critical but should be accounted for in thermal calculations.
