Rated 25 A at 40 °C, it carries that current continuously through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C — a thermal curve you need for panel ambient planning, not just the headline number. Breaking capacity is the real selector here: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 7.5 kA floor at 690 V tells you this breaker is sized for 400 V-class systems where fault current stays under 50 kA — not for high-fault 690 V installations.
Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact 3-pole footprint that fits standard MCCB panel cutouts.
