Current-Monitoring Relays
Screw Terminals with Knob
Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow. When current is outside a set range, they trip and cut power to prevent overheating, fire hazards, and stalling. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on a 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
Relays with knob adjustments have knobs right on the front where you can set your trip current. You can see that they're wired correctly and when they're actuated based on the LED indicators.
