Newark offers a comprehensive range of monitoring relays, ideal for safeguarding electrical systems and ensuring optimal performance. Our selection includes current, ground fault, insulation, phase and temperature monitoring relays from leading manufacturers. Designed to enhance safety and efficiency, these relays are available in various configurations for industrial and commercial applications.

Monitoring relays are protective devices that monitor key electrical parameters such as current, voltage, phase sequence, insulation resistance and temperature. They detect anomalies and trigger alerts or corrective actions to prevent equipment damage and system failure. These relays play a vital role in protecting motors, generators and other critical electrical equipment.

Current Monitoring Relays – Detect overcurrent, undercurrent and phase imbalance to protect motors and equipment. Ground Fault Monitoring Relays – Identify leakage currents to prevent electrical hazards and improve safety. Insulation Monitoring Relays – Measure insulation resistance to detect faults before they cause failure. Phase Monitoring Relays – Monitor phase sequence, loss and imbalance to ensure stable operation. Temperature Monitoring Relays – Detect overheating and activate cooling or shutdown systems.

Applications:

  • Industrial Automation – Protect motors and equipment from electrical faults.
  • HVAC Systems – Ensure efficient operation and prevent overheating.
  • Power Distribution – Maintain system stability and prevent blackouts.
  • Renewable Energy – Monitor electrical health in solar and wind systems.
