Newark offers high-performance thermal overload relays designed to protect motors from overheating and excessive current. Our relays are sourced from trusted manufacturers and are available in various configurations to match your specific application needs.

Thermal overload relays use temperature-sensitive elements to detect and respond to overheating conditions. When the motor exceeds the preset temperature limit, the relay disconnects the circuit, preventing damage to the motor and associated components.

Applications:

  • Industrial Motors: Preventing damage from thermal overload.
  • HVAC Systems: Ensuring safe compressor operation.
  • Pumps and Fans: Protecting motors in continuous operation.
