Three poles, thermal-magnetic trip (TM240 release), with an integral shunt trip (STL) for remote or emergency-off tripping via a separate control voltage. Breaking capacity runs from 75.6 kA at 240 VAC down to 11.9 kA at 690 VAC — enough for most industrial service-entrance or high-fault panelboard applications, provided the available fault current at the point of installation stays within those curves.
Rated 32 A continuous at 40 °C, and it holds that rating up to 50 °C without derating — above that it steps down to 31 A at 55 °C and 30 A at 70 °C. The shunt trip (STL) auxiliary release lets a remote pushbutton, PLC output, or safety relay open the breaker independently of the thermal-magnetic trip mechanism.
Width is 76.2 mm (3 in), height 130 mm (5.12 in), depth 70 mm (2.76 in) — a standard 3-pole MCCB footprint that fits most SENTRON distribution boards and third-party enclosures with the same cutout.
