How to choose a circuit breaker - Leviton breaker choices

Circuit Breaker Choices – Thermal Magnetic, Hydraulic Magnetic, or Smart?

Do you want to reduce nuisance tripping in your load center? Choosing the correct circuit breaker for your installation is an excellent first step. The Leviton Load Center offers Thermal Magnetic, Hydraulic Magnetic, and Smart circuit breakers. The critical difference between these breakers is how they react to overloads.

  • Thermal Magnetic Circuit Breakers can be affected by ambient temperature, so they’re an excellent choice for nearly all indoor installations where temperatures don’t fluctuate far from the average range.
  • Hydraulic Magnetic Circuit Breakers use a specialized solenoid and other components to trip the breaker on overload. This configuration provides for accurate tripping in even the most extreme temperature conditions.
  • Smart Circuit Breakers allow remote energy management, control, and monitoring. All of Leviton’s smart circuit breakers have Hydraulic Magnetic technology built-in, so you’re getting premium trip performance in an internet-connected package.  Download the My Leviton app on your phone, tablet, or desktop, and you will be able to control and monitor these breakers.

A load center is only as effective as the circuit breakers it houses. With Thermal and Hydraulic Magnetic and Smart circuit breaker options, Leviton provides flexibility for any installation. To learn more about the Leviton Load Center, visit
