MCCB for line protection
That means in a warm panel — say 50 °C ambient — you still get full 32 A continuous. Only above 55 °C does the available current drop, and only by 1–2 A. This is a solid thermal curve for a 32 A frame; no surprise derating below 50 °C.
Breaking capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and still 11.9 kA at 690 V. Even on a 415 V system, 75.6 kA covers most industrial distribution boards without needing a current-limiting upstream breaker.
Width 76.2 mm (3 in), height 130 mm (5.12 in), depth 70 mm (2.76 in). That 70 mm depth is compact for a 3-pole MCCB with this interrupting rating — it fits standard 200 mm deep enclosures without crowding the door. The auxiliary switch configuration supplied is 1 auxiliary switch + 1 trip alarm switch (HQ design), which gives both a NO/NC signal for status and a dedicated alarm contact that closes only on a trip event.
