Product details

The TM-D trip provides LI protection: thermal (L) for overload and magnetic (I) for short-circuit. That's the standard thermal-magnetic curve for distribution — no electronic adjustment, just a fixed bimetal and coil.

Standards, isolation, and mounting

Conforms to EN/IEC 60947-1 and EN/IEC 60947-2, including Annex H for EMC. Fixed mount on a backplate, IP20 finger-safe terminals. Screw terminals front-connected both top and bottom, 25 mm pole pitch. The grey (RAL 7035) housing is the standard industrial enclosure colour.

Durability and thermal budget

Rated for 8000 electrical cycles at 415 V at rated current, and 30000 mechanical cycles. Power dissipation is 18.7 W per pole. Lifecycle status is current production.

Frequently asked questions
