Rated 25 A continuously from 40 °C down to 50 °C; derates to 23 A at 65–70 °C, which matters if the breaker sits next to heat-generating contactors in a sealed enclosure. Interrupting capacity drops with voltage: 52.5 kA at 415 V, 32 kA at 440 V, 7.5 kA at 500 V and 690 V — check your system voltage and available fault current before committing the BOM line. Maximum power loss 8.5 W, typical for this frame size; factor into enclosure thermal calculations. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — standard SENTRON 3VA1 frame footprint. Trip indicator visible on the front face for quick visual check during commissioning.
