Description
The ABB TF42-35 is a thermal overload relay designed to provide dependable motor and equipment protection across a wide range of commercial and industrial HVAC applications. With an adjustable current setting range of 29.0–35.0A, this relay guards against overload conditions that can cause costly motor burnout and unplanned downtime.
Product Overview
The TF42-35 belongs to ABB’s TF42 series of thermal overload relays, engineered to work in conjunction with ABB contactors for a complete motor starter solution. The relay monitors current draw and trips the circuit when sustained overcurrent conditions are detected, protecting compressors, fan motors, pumps, and other motor-driven HVAC components.
