Breaking capacity runs 121 kA at 240 V and still holds 75.6 kA at 415 V, which covers most industrial service-entrance and feeder applications without needing a current-limiting upstream device. The TM240 overcurrent release is a thermal-magnetic type — thermal for overload, magnetic for short-circuit — tuned to a 240 A fixed magnetic pickup, so it's a straight swap into a panel spec'd for a standard MCCB with that trip curve.
The 160 A rating holds flat from 40 °C to 50 °C, then derates to 150 A at 70 °C — that's a gentle slope, so in a warm panel (say 55 °C) you still get 158 A of headroom. At 690 V the breaking capacity drops to 11.9 kA — that's still enough for most 690 V motor branch circuits, but verify against your available fault current if you're on a high-capacity transformer.
Physical Fit & Panel Integration
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB envelope for a 160 A frame.
