    Different Types of Square D Breakers

    We offer a wide variety of Square D circuit breaker types. Some of our most common orders include:


    Square D Molded Case Circuit Breakers

    Square D’s molded case breakers are ideal for protecting against thermal overloads, ground faults, and short circuits. These are available as one, two, three, and four-pole circuit breakers. 

    The Square D molded case circuit breakers we carry range in capacity from 125A to 2000A and can be used in both residential and commercial applications. 

    Two of Square D’s most popular molded case circuit breakers are their HomeLine and QO series. Note: QO and HomeLine breakers are not interchangeable, so always verify that the breaker you’re ordering is the correct one for your application. 


    Square D QO™ Circuit Breakers

    Square D’s Qwik-Open circuit breakers (QO breakers) live up to their name, as they are well known for their record opening speeds (1/60th of a second). 

    Another feature that makes these circuit breakers popular is their easy-to-spot visual trip indicator that helps you quickly find tripped breakers. 

    Note: these easy-plug-in breakers are designed for use in NQ and NQOD panelboards, QO load centers, Speed-D switchboards, and OEM mounting bases.
