    Distribution bars simplify wiring by powering multiple adjacent circuit breakers without needing separate wires for each one. This cuts down on assembly time and space. Cut them to the number of terminals that you need.
    Distribution bar terminal covers shield unused, live terminals on distribution bars to prevent injury and damage.
    Auxiliary contacts send a signal to other equipment when the circuit trips. They can activate a warning light, initiate a shutdown, or start a backup power source.
    Shunt trips receive a signal from equipment to trip your circuit breaker in situations other than overload or short circuit conditions. For example, use them with a smoke detector to shut off power to a system in the event of a fire.
    Extension terminals raise the wire connection point above distribution bars for easy access to connect power to a set of circuit breakers.
    Also known as supplemental protectors, these circuit breakers mount directly to DIN rail downstream from a branch circuit breaker to protect a single piece of equipment. Because they are thermal-magnetic, these breakers trip two ways. They either trip when heat is generated slowly by consistent low-level overload current, or they trip quickly when the magnetic coil senses a high-current short circuit.
    Distribution bar end covers seal the live ends of distribution bars to prevent injury and damage.

    Distribution Bar

    Distribution bar terminal covers shield unused, live terminals on distribution bars to prevent injury and damage.
    Auxiliary contacts send a signal to other equipment when the circuit trips. They can activate a warning light, initiate a shutdown, or start a backup power source.
    Shunt trips receive a signal from equipment to trip your circuit breaker in situations other than overload or short circuit conditions. For example, use them with a smoke detector to shut off power to a system in the event of a fire.
    Extension terminals raise the wire connection point above distribution bars for easy access to connect power to a set of circuit breakers.
    Mount these circuit breakers directly to DIN rail to protect equipment and wiring in an area of your facility from overloads and short circuits. Because they are thermal-magnetic, these breakers trip two ways. They either trip when heat is generated slowly by consistent low-level overload current, or they trip quickly when the magnetic coil senses a high-current short circuit.
    Distribution bars simplify wiring by powering multiple adjacent circuit breakers without needing separate wires for each one. This cuts down on assembly time and space.

    B-trip circuit breakers are best for protecting sensitive equipment, such as programmable logic controllers (PLCs) and sensors, which could be damaged by a spike in current. These circuit breakers will trip if a rush of current reaches 3 to 5 times their rated current.

    Harsh-Environment Circuit Breakers

    Built to resist vibration and corrosion in harsh environments, these circuit breakers protect against overload and short circuits in low-voltage automotive and other electronic applications. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
    Lever Manual Reset and Push-Pull Button Manual Reset—Push-pull button and lever style breakers can be used as an on/off switch.
    UL 1077—Place UL 1077-rated breakers downstream from a branch circuit breaker to protect a single piece of equipment. They are also known as supplemental protectors.
    Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

    Use with Siemens EQ series breaker boxes. Because they are thermal-magnetic, these circuit breakers trip two different ways. They either trip when heat is generated slowly by consistent low-level overload current or quickly when the magnetic coil senses a high-current short circuit.
    UL 489—These circuit breakers meet UL 489 requirements for branch circuit protection, so they protect downstream equipment and wiring from overloads and short circuits.

    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.

    Fixed-current breakers come set to trip at a specific current. This prevents accidental or unauthorized changes to when they’ll trip.
    Breakers with digital input/outputs send and receive signals, so you can remotely check the status of your breaker, reset it, and turn it on and off.

    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 digital input/outputs send and receive signals, so you can remotely check the status of your breaker, reset it, and turn it on and off.
    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.

    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.

    Install these circuit breakers into Cutler-Hammer CH series breaker boxes. Because these circuit breakers are thermal-magnetic, they trip two different ways. They either trip when heat is generated slowly by consistent low-level overload current or quickly when the magnetic coil senses a high-current short circuit.
    UL 489—They meet UL 489 requirements for branch circuit protection and are certified as current limiting, so they protect equipment by minimizing passing current during a short circuit.
    Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

    Unlike breakers that trip thermally, these breakers have a hydraulic-magnetic trip mechanism, so they aren’t affected by changes in temperature. Instead, these circuit breakers trip when they hydraulically sense consistent low-level overload current, or they trip quickly when the magnetic coil senses a high-current short circuit. Use the threaded holes on the face to install them through panels, enclosure covers, or walls to keep them close to the equipment they protect.

    Small enough to fit in tight spaces, these circuit breakers mount through panels. They are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
    UL 489—These circuit breakers are UL 489-rated for branch circuit protection.
    Breakthrough Current @ Voltage—Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
