Q: How does a thermal overload relay protect a motor?
A: It monitors the current flowing to the motor and trips the circuit if the current exceeds a preset level for a specific duration, preventing overheating and potential motor damage.

Q: Can the relay be adjusted for different motor sizes?
A: Yes, the adjustable current settings allow the relay to be calibrated to match the full-load current of various motors, ensuring appropriate protection.

Q: What is the significance of phase failure sensitivity?
A: Phase failure sensitivity enables the relay to detect the loss of a phase in a three-phase system, which can cause unbalanced currents and potential motor damage, allowing the relay to trip and protect the motor.

Q: What is the purpose of the auxiliary contacts in the thermal overload relay?
A: The auxiliary contacts (1 NO and 1 NC) are used for signaling and control purposes within the motor control circuit, allowing for integration with other control devices.

Q: Can the relay be manually reset after tripping due to an overload?
A: Yes, the relay offers both manual and automatic reset options, providing flexibility based on application needs.

Q: Is this thermal overload relay compatible with other contactor models?
A: This specific model is designed for use with CR01C-CR12C (MC10 to MC22) contactors.
