Product details

It carries a continuous current of 40 A at 40 °C, with minimal derating up to 70 °C (37 A at 70 °C). The TM240 thermal-magnetic release provides overload and short-circuit protection, with a fixed thermal element and a magnetic trip calibrated for the 40 A frame.

Rated breaking capacity reaches 121 kA at 240 V AC, dropping to 75.6 kA at 415 V AC, 52.5 kA at 440 V AC, and 11.9 kA at 500/690 V AC.

Fit and mounting — panel integration

Measuring 76.2 mm wide, 130 mm high, and 70 mm deep, this MCCB fits standard 3-pole MCCB footprints. The 70 mm depth keeps it within typical enclosure depths for 200–400 A rated switchboards.
