Overview

The ABB TF42-13 (SKU: TF42-13) is an economical electromechanical thermal overload relay from ABB Electrification, designed for reliable main circuit protection of electric motors. This three-pole relay features bimetal tripping elements that directly and indirectly heat from motor current. In overload conditions, the bimetal elements bend, triggering a relay release and changing contact positions (95-96 / 97-98). It offers Trip Class 10 protection, suitable for a wide range of motor applications. Key features include manual or automatic reset selection, phase loss sensitivity compliant with IEC/EN 60947-4-1, and integrated temperature compensation for stable operation across ambient temperatures. The relay incorporates TEST and STOP functions with clear trip indication on the front panel. It is designed for direct connection to ABB AF09...AF38 block contactors, with single mounting kits available as accessories. The TF42-13 is ATEX certified and manufactured in the USA. Main circuit terminals accept rigid conductors from 0.75 to 4 mm² and flexible conductors with ferrules from 0.75 to 4 mm², with a tightening torque of 1.5-2.5 Nm. Auxiliary circuit terminals accommodate rigid conductors from 0.75 to 4 mm² and flexible conductors with ferrules from 0.75 to 2.5 mm², with a tightening torque of 1-1.2 Nm. The housing is IP20 protected, and main circuit terminals are IP10.
