Description
The ABB TF42-29 is a thermal overload relay engineered to provide dependable overcurrent and overload protection for motors used in HVAC, commercial, and industrial control applications. Designed to work in conjunction with ABB contactors, this relay monitors motor current draw and trips the circuit when sustained overload conditions are detected — helping prevent costly motor burnout and unplanned downtime.
Key Features
- Thermal overload protection for three-phase and single-phase motor circuits
- Designed for use with ABB AF and A-Series contactors
- Manual and automatic reset options for flexible system integration
- Trip class design provides reliable protection across varying load conditions
- Compact, DIN-rail compatible construction for easy panel installation
- Auxiliary contacts for remote signaling and control circuit integration
- Phase-loss sensitivity to protect motors from single-phasing conditions
Typical Applications
- HVAC compressor and fan motor protection
- Commercial and industrial motor starter assemblies
- Pump and blower motor control panels
- Building automation and mechanical room electrical panels
