Phoenix Contact Miniature Circuit Breakers

Phoenix Contact miniature circuit breakers are designed to protect low-voltage devices and circuits from overload and short-circuit conditions in industrial control panels. These device circuit breakers provide selective protection by isolating only the affected circuit while allowing the rest of the system to remain operational, helping reduce downtime and simplify troubleshooting.
Phoenix Contact offers electronic, thermomagnetic, and thermal device circuit breakers, each with distinct tripping characteristics. Electronic circuit breakers provide extremely fast tripping times within milliseconds, making them well suited for sensitive electronic loads. Thermomagnetic breakers combine thermal and magnetic tripping elements to respond to both sustained overloads and high short-circuit currents, while thermal breakers trip progressively faster as overload levels increase.
These miniature circuit breakers are commonly used in assembly machines, production systems, and control cabinet applications to protect PLCs, sensors, actuators, motors, valves, and relays. Selecting the appropriate breaker requires consideration of the load’s nominal current and starting current to ensure reliable protection without nuisance tripping.
