    Sequenced Latching Relays

    Image of Product. Front orientation. Contains Annotated. Latching Relays. Sequenced Latching Relays.
    These relays switch through a series of different circuit configurations every time they receive an input voltage. The input voltage latches them in position, so they don’t require a constant voltage to stay switched. Use them to control motors, pumps, and lighting. The covered terminals prevent contact with live connections. Mount to 35 mm DIN rail. Also known as step relays.

    High-Current Lighting Relays

    Switch lighting systems on and off—these relays can handle the high switching current on large overhead light systems. They control multiple circuits, so you can manage several lights across your facility with just one relay. For example, use them to switch overhead lights along with lighted signs in different parts of your warehouse. These relays come set for normally-open switching, but you can change them to normally-closed by turning the contacts around with a screwdriver.

    Mechanically held relays are ideal for applications that don’t need to be switched very often, such as lights that stay on all day. Since they switch on and off with a quick burst of input voltage rather than needing constant power, they’re more energy efficient than electrically held relays.

    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.

    Relays have an LED indicator that tells you if your lights are using primary or backup power and when these relays require maintenance. They also have a test switch to make sure the system is working.
    Unthreaded Through-Hole Mount—Relays that mount into an unthreaded through hole install into knockouts in junction boxes and light fixtures.
    Fastener Mount—Fastener-mount relays are ideal when space is tight or you want to hide your relay. They fit inside a ballast channel to keep everything contained within your fixture housing.

    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.

    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.
    Knob Adjustment—Relays with knob adjustments have knobs right on the front where you can set your trip current.
    LED Indicator—Relays with an LED indicator show the status of your relay, so you know it is wired correctly and when it is actuated.

    DIN-Rail Mount

    Relay-Socket Mount

    Prevent changes in frequency from damaging sensitive equipment. Often used with motors, fluorescent lighting, and controllers, these relays cut power to your device if the frequency falls outside the set range. Switches on the front of these relays let you set your trip frequency and time. You can see that they're wired correctly and when they're actuated based on the LED indicators. Rated IP20, these relays have recessed terminals that keep fingers and other objects from touching live circuits.
    DIN-Rail Mount—DIN-rail mount relays snap onto 35 mm DIN rail (also known as DIN 3 rail) for fast installation.
    Relay-Socket Mount—Relay-socket mount relays plug into a socket (sold separately), which is required for installation.
