ABB TF42-1.0 Thermal Overload Relay | 0.74A to 1.0A, Class 10

1SAZ721201R1023
ABB TF42-1.0 is a highly durable and economical thermal protection device designed for the main motor circuit. Engineered for 1 Amp applications, it features an adjustable setting range of 0.74 to 1.00 Ampere. This relay provides Class 10 trip characteristics, ensuring your motor is protected against overloads, phase failures, and excessive heat buildup.

Key Technical Features:

Bimetallic Tripping: Reliable Class 10 thermal protection ensures the motor is disconnected before winding damage occurs.

Phase Failure Detection: Built-in sensitivity to phase loss protects the motor from running on two phases, a common cause of burnouts.

Temperature Compensation: Maintains accurate performance in ambient temperatures from -25°C to +60°C, ideal for fluctuating industrial climates.

Dual Reset Function: Features a reset button that is easily switchable between Manual and Automatic modes, plus an integrated Test/Stop function.

Compact Design: Plugs directly into the underside of AF09, AF12, AF16, AF26, AF30, and AF38 contactors to save DIN rail space.
