1SAZ721201R1043
ABB TF42-10 is an economical and reliable solution for motor protection against overloads and phase failures. With an adjustable range of 7.6 to 10.0 Amperes, it offers specialized Class 10 tripping to ensure your motors are disconnected before overheating leads to failure. Designed for industrial durability, it integrates flawlessly with the AF series contactors to create a compact, space-saving motor starter.

Key Technical Features:

Bimetallic Protection: Provides a precise Class 10 trip curve, ideal for standard industrial motor starting and running.

Phase Failure Protection: Automatically monitors phase balance and trips the circuit in the event of a phase loss to prevent motor winding burnout.

Built-in Temperature Compensation: Ensures accurate tripping across a wide temperature range (-25°C to +60°C), preventing nuisance trips in hot panels.

Flexible Control Options: Features a selectable Manual or Automatic reset, a Test function for safety checks, and a Stop button.

Direct Contactor Mounting: Saves installation time and wiring costs by plugging directly into AF09, AF12, AF16, AF26, AF30, and AF38 contactors.
