It carries a 187 kA interrupting rating at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — these numbers define the maximum fault current it can safely clear at each voltage level without upstream coordination failure. Rated insulation voltage Ui is 800 V, and the breaker maintains full 80 A current rating from 40 °C through 50 °C ambient; above that it derates gradually to 72 A at 70 °C. The TM240 release is adjustable for the long-time pick-up, with a maximum delay tr of 1 s — useful for coordinating with downstream branch breakers on motor or feeder circuits.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the width is a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.
