ABB TF42-7.6 Thermal Overload Relay TF42-7.6 Series

ABB TF42-7.6 Thermal Overload Relay is a three-pole motor-protection device in the TF42 family designed to guard the main circuit from overload and phase failure. Identified by part number 1SAZ721201R1040, it covers a rated current of 5.7–7.6 A (Ie) and is rated for 690 V AC or 600 V DC, making it suitable for standard industrial motor circuits up to those voltages. The device uses a bimetal tripping element and mounts directly to ABB block contactors, with single mounting kits available as accessories. Key features include trip class 10 accuracy, a normally closed (NC) trip contact and a normally open (NO) signal contact, and the option to choose auto- or manual-reset, a trip-free mechanism, STOP function, and a trip indication. This overload relay is designed for direct integration in motor starters to provide reliable overload protection and fast response to overload or phase loss, helping prevent motor damage and downtime.
