    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 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.

    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.

    C-trip circuit breakers are the most common. They’re best for applications such as lighting and control panels, where equipment startup causes a moderate spike in current. They won’t trip until a rush of current reaches 5 to 10 times their rated current.

    Blade-Style Circuit Breakers

    Protect against overload and short circuits in low-voltage automotive and other electronic applications. These circuit breakers can replace type ATC, AF, ATO, and 257 blade-style fuses. They are thermal, so they trip when heat is generated by overload current.
    Automatic Reset
    Image of Product. Front orientation. Circuit Breakers. Blade-Style Circuit Breakers, Automatic Reset.
    Automatic reset breakers don’t require you to manually reset them after they trip, so they’re good for areas where the breaker isn’t easily accessed. These breakers reset once they cool. However, they will trip repeatedly if the overcurrent condition continues.
