Newark provides a versatile range of electronic overload relays to protect motors and equipment from excessive current and overheating. Available in various sizes and configurations, these relays are designed to meet the needs of industrial, commercial and manufacturing sectors. Our range ensures quick response times and minimal system downtime.

Electronic overload relays monitor motor current and automatically disconnect the circuit when excessive current flow is detected. They use electronic sensing to measure and respond to overload conditions more accurately than traditional relays, offering improved protection and operational reliability.

Applications:

  • Industrial Machinery: Protecting motors from overload damage.
  • HVAC Systems: Ensuring reliable operation of compressors and fans.
  • Manufacturing: Preventing overheating of automated systems.
