That 160 A holds flat from 40 °C through 50 °C, then derates to 142.4 A at 70 °C — so in a crowded panel where ambient climbs, you still have headroom before nuisance tripping. Breaking capacity is the real selector here: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V. The 690 V rating is useful for 600 V class North American systems or mining gear running 690 V. Panel fit: 105 mm wide, 158 mm tall, 70 mm deep.
Trip unit and auxiliary contacts — what you get out of the box
The TM240 overcurrent release is a fixed thermal-magnetic design — no electronic adjustment, no communication module, no voltage trigger. If you need those, you are looking at a different 3VA variant with the electronic trip. That storage floor matters if the spare sits in an unheated warehouse over a northern winter.
