LA-Frame Circuit Breaker
LA-Frame circuit breakers are molded case circuit breakers designed to provide reliable overcurrent protection in industrial and commercial electrical systems. As part of the Square D by Schneider Electric molded case circuit breaker portfolio, LA-Frame breakers are used to protect circuits and equipment from overloads and short circuits while supporting dependable system operation. Their compact unit-mount design makes them well-suited for installations where space efficiency and straightforward integration are important.
Square D LA-Frame molded case circuit breakers are available in 2-pole and 3-pole configurations and are commonly used in DIN rail-mounted or unit-mount applications, depending on the system design. These breakers use thermal-magnetic protection, combining a thermal trip element for sustained overcurrent conditions with a magnetic trip element for instantaneous response to higher fault currents. This dual protective function helps provide dependable circuit interruption across a wide range of operating conditions.
LA and LH molded case circuit breakers are available in current ratings from 125 to 400 amps and are used in applications such as industrial enclosures, panelboards, switchboards, busway plug-in units, combination starters, and motor control centers. With multiple construction options, including unit-mount, I-Line, and rear-connect styles across related frame types, these breakers support flexible installation in many distribution and control environments where recognized protection and long-term reliability are required.
