Farnell provides a wide range of current monitoring relays, ensuring reliable protection for electrical systems in industrial and commercial settings. With various current thresholds and adjustable settings, our relays deliver precise monitoring and quick response to overcurrent and undercurrent conditions.

Current monitoring relays detect abnormal current flow in electrical circuits. They protect motors, transformers and other electrical equipment by disconnecting the circuit when a current fault is detected, preventing overheating and equipment damage.

Key Features:

  • Adjustable current ranges and trip delays for tailored protection.
  • Overcurrent and undercurrent detection to prevent motor burnout.
  • Single-phase and three-phase compatibility for versatile use.

Applications:

  • Motor Protection – Prevent damage from overloading and phase imbalance.
  • Power Distribution – Maintain stability in electrical grids.
  • Industrial Equipment – Ensure smooth operation of heavy machinery.
