ABB 07 TA 60 Thermal Overload Relay Module for Motor Protection

The 07 TA 60 protects motors from excessive current and overheating conditions. This thermal overload relay module sits between the contactor and the motor circuit. You can use it for pump, fan, and conveyor motor protection.

Key Technical Parameters

The table below lists all essential technical specifications for this thermal overload relay module.

Physical Characteristics and Installation

This thermal overload relay module weighs approximately 0.48 kg for direct panel mounting. Its dimensions measure 85 mm x 110 mm x 75 mm for compact starter assemblies. First, mount the 07 TA 60 directly below your main contactor. Then, connect the motor supply wires through the built-in current transformers. Finally, wire the auxiliary contacts to your PLC input module. The front dial allows easy current setting adjustments without tools.

Current Settings and Trip Characteristics

The 07 TA 60 features an adjustable current range from 40 A up to 57 A. You can select three different trip classes for your application. Class 10 trips in 10 seconds for standard motor starting. 20 seconds for high-inertia loads. Class 30 allows 30 seconds for very heavy starting conditions. The module trips within 2 seconds during single-phase conditions. Consequently, this relay prevents motor burnout from phase loss.

Auxiliary Contacts and Environmental Compensation

This module includes one normally open and one normally closed auxiliary contact. You can wire these contacts for PLC fault monitoring. The 07 TA 60 compensates for ambient temperatures between -20°C and 60°C. Therefore, the trip accuracy remains stable in varying environmental conditions. The electrical durability reaches 100,000 operations for long service life. Use this relay for complete motor starter assemblies.
