    DIN-Rail Mount Electronic Circuit Breakers

    An electronic trip mechanism makes these circuit breakers fast, precise, and consistent. They continuously monitor current and trip at a precise value compared to the much wider current range in traditional thermal-magnetic breakers. They're good for protecting devices that could be easily damaged by overcurrent such as sensors, HMIs, and controllers. Because they trip electronically, they don't require the bulky housing necessary for thermal trip mechanisms, so they take up less space in your control cabinet. They also eliminate the need for accessories, such as shunt trips, because they can be remotely monitored and controlled. For at the source troubleshooting, they have an indicator light and on/off/reset button for each circuit. To make sure your equipment is receiving the correct voltage, these breakers will also trip when the supply voltage goes under or over a set value.

    Adjustable-current breakers let you choose the current at which they’ll trip. As your operation changes, you can adjust when these breakers will trip rather than replacing the entire breaker.
    Breakers with IO Link give you more control than breakers with digital input/outputs. Not only can you check the status to reset or turn your breaker on and off, but you can also adjust their current and view current in real-time. This is helpful when troubleshooting issues such as a breaker that repeatedly trips.
    4 Circuits Controlled and 8 Circuits Controlled—Breakers that control 4 or 8 circuits allow you to individually set each circuit. If one trips, the others will keep working.

    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.
    Spring-Clamp-Terminal Wire Connection—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.
    IO Link Communication Protocol—Relays with IO link can be programmed, monitored, and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.

    Detect and mitigate ground faults to prevent harm to equipment, circuits, and people. These relays monitor the differential between incoming and outgoing current, also known as residual current. When the balance is off, they trip and cut power to the circuit. These relays are highly sensitive, so you can trust them to de-energize faulty circuits before a minor issue becomes a major one. Rated IP20, they have recessed terminals that keep fingers and other objects from touching live circuits. Mount them on 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
    These relays require a current-indicating ring (sold separately) to operate. Choose a ring that is large enough for your lines to pass through. Feed the lines of the circuit through the center of the ring and connect the indicating ring output to the relay.
    Spring-Clamp-Terminal Wire Connection—Relays with spring-clamp terminals connect and disconnect to wire without screws. Because they don’t have screws, there’s less of a risk that they will loosen over time, even when they’re under vibration.
    IO Link Communication Protocol—Relays with IO link can be programmed, monitored, and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.

    Voltage-Monitoring Relays

    Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage.

    Multifunction Monitoring Relays

    Image of Attribute. Front orientation. Contains Annotated. Monitoring Relays. Multifunction Monitoring Relays.
    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.
    These relays use IO Link, so they can be programmed, monitored, and reset remotely by connecting them to a programmable logic controller (PLC), human-machine interface (HMI), or computer. If you want to program them locally, they have a keypad.
