EasyPact TVS thermal overload relays are designed to protect a.c. circuits and motors against:

• overloads
• phase failure
• Long starting time
• prolonged stalled rotor condition.

The thermal relay controls permanently the current driven by the motor. When this current exceeds the setting it's auxiliary contacts will change state, causing the motor to stop.

1. Adjustment dial Ir.

2. Test button.

Operation of the Test button allows:

3. Stop button. Actuates the N/C contact; does not affect the N/O contact.

4. Reset button.

5. Trip indicator.
