Product details

Thermal overload relay for AF contactor line

The ABB TF42-13 is a 3-pole thermal bimetal overload relay rated at 13 A, with an adjustable range of 10 to 13 A.

Mounts directly on AF9–AF38 contactors

This relay is designed for direct mounting on ABB AF9 through AF38 frame contactors. The mechanical interlock and power circuit connection happen through the contactor's own terminals — no separate wiring between contactor and overload for the main poles. Selectable manual or automatic reset via the front dial.

Frequently asked questions

What is the closest functional second-source for TF42-13?

The closest functional peer is the TF42-1.3, which shares the same 3-pole NEMA form factor and 10-13 A adjustment range. The TF42-13 drops into the same panel footprint and mounts on the same AF9-AF38 contactors without rewiring.
