    Screw Terminals

    Knob Adjustment

    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.
    Knob Adjustment—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.

    Voltage-Monitoring Relays

    Image of Attribute. Front orientation. Contains Annotated. Monitoring Relays. Voltage-Monitoring Relays.
    Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage. These relays continuously monitor your AC or DC power supply and trip when the voltage is outside a set range. 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.
    With Spring-Clamp Terminals—Relays with spring-clamp terminals connect and disconnect to wire without screws. Because there’s no screw, these connections are less likely to loosen over time, even in high-vibration environments.
    Knob Adjustment—Relays with knob adjustments have knobs right on the front where you can set your trip voltage. You can see that they're wired correctly and when they're actuated based on the LED indicators. If you want to mount these relays to a surface instead of DIN rail, they have mounting holes.
