1SAZ721201R1038 ABB - TF42-5.7

The ABB TF42-5.7 thermal overload relay is a cost-effective and dependable electromechanical device designed to safeguard main circuits. It provides swift and reliable protection for motors against overload conditions and phase failures, ensuring operational continuity. This relay features trip class 10, indicating its response time to overloads, and incorporates temperature compensation to maintain accuracy across varying ambient temperatures. Equipped with a trip contact (NC) and a signal contact (NO), it facilitates seamless integration with control systems for alarm and shutdown functions. Users can select between automatic or manual reset modes, adapting to diverse application requirements. The trip-free mechanism ensures that the relay cannot be held closed during an overload, enhancing safety. An integrated STOP function allows for immediate motor shutdown, while a trip indication provides clear visual feedback on the relay's status. These overload relays are designed for direct connection to block contactors, simplifying installation. Single mounting kits are available as accessories, offering flexible mounting options.
