    Smart Multifunction Monitoring Relays

    Image of ProductInUse. Front orientation. Monitoring Relays. Smart Multifunction Monitoring Relays.
    Remotely control these relays through an app on your smartphone—they simultaneously monitor phase, voltage, and frequency. The downloadable app lets you change the tripping range, modify settings, and save programs to apply to multiple relays. Tap your smartphone or tablet to the relays to connect to them. They use NFC (near field communication), so you don’t need to manually pair them like Bluetooth devices.
    You’ll often see these relays used to protect motors, generators, and other three-phase circuits from burning out or overheating. They'll switch the circuit off if they detect voltage or frequencies outside of the set range or phase loss, imbalance, or reversal. You can see that they're wired correctly and when they're actuated based on the LED indicators. Rated IP20, they 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.

    Motor Starter Overload Protectors

    Image of Product. Front orientation. Motor Starter Overload Protectors.
    Upgrade motor starters that use thermal overload protection with these solid-state overloads—they don't use heating elements, so enclosure ventilation and cooling is not required. All have a full-load amp adjustment dial to accommodate circuits with different full-load amp ratings.
    If the full-load amp rating is not shown on your motor’s faceplate, estimate the current rating (given the motor’s horsepower and voltage).

    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.
    Monitoring Relays

    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.

    Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating. They'll switch the circuit off if they detect voltage or frequencies outside of the set range or phase loss, imbalance, or reversal. Rated IP20, they 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.
