The TM240 thermal-magnetic trip unit is set for an 800 A nominal rating (In), with adjustable overload protection (Ir) from 560 A to 800 A and short-circuit protection (Ii) adjustable from 5 to 10 times In. This unit ships with an integrated undervoltage release (24 V DC) and provisions for up to two auxiliary switch changers, so it arrives ready for remote status feedback and undervoltage protection in a control circuit — no separate accessory ordering needed for those functions.
Deployment context
Mounts in a standard switchgear or distribution panel on a DIN rail or mounting plate via the frame 1000 footprint. The 70 kA SCCR at 415 V makes it suitable for high-fault-capacity installations such as industrial main feeders or large motor control centers where coordination with downstream breakers is required.
