Product details

MCCB for line protection — 40 A frame, TM240 release

The TM240 overcurrent release is a fixed thermal-magnetic type — no electronic adjustment, no communication function. That makes it a straightforward drop-in for standard feeder or branch protection where you don't need selective coordination tuning. Interrupting capacity is specified per voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.

The width is a standard 3-inch (76.2 mm) footprint, so it aligns with common DIN-rail or backplate mounting patterns.

Frequently asked questions

What does the TM240 release designation mean?

TM240 indicates a fixed thermal-magnetic overcurrent release — thermal element for overload protection, magnetic element for short-circuit protection. No electronic adjustment or communication interface.
