Line protection MCCB with TM240 release
Rated 100 A continuously at 40 °C ambient, it holds that rating through 50 °C before derating begins — at 55 °C it's still good for 98 A, and at 70 °C it delivers 91 A. That thermal curve means you can mount it in a warm panel without oversizing the frame. The interrupting ratings are what set this frame apart: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The auxiliary switch configuration supports up to 4 HQ auxiliary switches, though this unit ships without a trip indicator or undervoltage release.
