It carries a 25 A continuous rating at 40 °C, with a 3-pole configuration that handles three-phase circuits.
This breaker's interrupting rating drops as line voltage rises: 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 11.9 kA at 690 V is still adequate for most industrial 690 V distribution, but if your fault study shows higher available current at that voltage, you need a larger frame.
The 25 A rating holds from 40 °C up to 50 °C. At 55 °C it derates to 24 A, and at 65 °C to 23 A. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The 76.2 mm width (3 inches) matches the typical 25 mm per pole spacing for busbar connection. Maximum power loss is 8.5 W, so ventilation in a sealed enclosure is advisable if you're grouping several breakers.
