Ever worry a minor fault might bring your entire process to a halt?

With our Phoenix Contact device circuit breakers you don’t have to.

These breakers selectively shut down only the affected actuator or sensor, so your operations keep running without a hitch.

Below is a simplified guide to picking the perfect breaker.

Thermal Circuit Breakers

 • Overload Protection: Suitable
 • Short-Circuit Protection: Unsuitable
 • Best For: Preventing damage from overloads when short-circuit risk is minimal

Thermal-Magnetic Circuit Breakers

 • Overload Protection: Suitable
 • Short-Circuit Protection: Ideal
 • Best For: Overload, short circuits, and long cable paths (thanks to the SFB tripping characteristic)

Electronic Circuit Breakers

• Overload Protection: Ideal
• Short-Circuit Protection: Ideal
• Best For: Overload, short circuits, line attenuation, high input capacitance, and long cable paths - offering the most comprehensive protection.
