Its TM240 thermal-magnetic overcurrent release handles overload and short-circuit faults without an undervoltage or shunt trip module — the listing confirms no undervoltage release and no voltage trigger. At 415 V the interrupting rating drops to 52.5 kA, and at 690 V to 11.9 kA — still adequate for most industrial motor branch circuits.
Rated current holds at 40 A from 40 °C through 50 °C, then derates to 39 A at 55–60 °C and 38 A at 65 °C, 37 A at 70 °C — a gentle slope that keeps the breaker usable in warm enclosures without oversizing. Power loss is 10.8 W maximum — relevant for thermal management in a tightly packed panel. The trip indicator gives a visual flag when the breaker has tripped, saving troubleshooting time on a line-down call.
The 3-pole footprint fits standard Siemens SENTRON mounting bases and busbar systems. The auxiliary switch configuration is 1 auxiliary + 1 trip alarm switch (HQ) — verify the wiring diagram for your alarm circuit. No communication module is fitted, so this is a standalone breaker; if you need remote monitoring, order the communication-capable variant separately.
