This current monitoring relay is designed by Tense Electronics to protect electrical loads (such as three-phase motors, heaters, and transformers) from high current damage. It also can monitor electrical current on a main or priority circuit. If the current exceeds a set threshold, the relay cuts off non-priority circuits to prevent breaker trips, then automatically restores them when current drops.

 

Key Specifications & Features

  • Tripping Current Range: Adjustable overload protection between 40A and 100A.
  • Current Asymmetry: Fixed at 50% error threshold to guard against phase imbalances.
  • Display Interface: Equipped with a 3×3 digit LED display for real-time monitoring of three-phase currents.
  • Operation Reset Modes: Features three user-adjustable reset methods: Automatic, Semi-Automatic, and Manual.
  • Time Delays: Fully adjustable error delay times (0.1 to 20 seconds) to prevent nuisance tripping during temporary inrush currents.
  • Mounting: Standard DIN rail installation.
  • Included Components: The retail box comes complete with required external current transformers.

Operational Principle

  • Startup: When energized, the relay activates, illuminating the OUT indicator and closing the circuit via its output contact.
  • Overload Event: If the drawn current on any phase surpasses the defined threshold value (A>), the ERR warning light turns on, and a localized countdown timer begins.
  • Tripping Action: If the overcurrent state outlasts the preconfigured delay window, the relay safely cuts the contact output, turning off the OUT light to isolate the downstream load.

Primary Application

Unlike traditional mechanical thermal relays, the microprocessor-based TRM-100 monitoring relay provides much more precise real-time current tracking and protection against phase imbalances or overcurrent faults, effectively extending the service life of industrial electric motors.
