The 40 A rating holds flat from 40 °C up to 50 °C, then derates to 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. This is a 3-pole unit with a shunt trip release (STL) for remote opening and an auxiliary contact block configured as 2 auxiliary switches plus 1 trip alarm switch (HQ).
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep. Front protection is IP40.
It includes a shunt trip release (STL) for remote tripping. There is no undervoltage release, no ground-fault monitoring, and no phase-failure detection.
