EB3040L - 40Amp Circuit Breaker Description
EB3040L - 40Amp Circuit Breaker
When you're maintaining an older electrical system, finding the right replacement breaker isn't just about matching amperage—it's about preserving compatibility with the equipment already in place. The EB3040L Type EB circuit breaker was designed for use in compatible Type EB panelboards manufactured before 1989, making it a practical choice for facilities that continue to rely on proven electrical infrastructure.
This 40 amp, 3-pole thermal-magnetic circuit breaker combines the ratings and configuration needed for many existing three-phase electrical systems. Its thermal-magnetic trip mechanism responds to both overload conditions and short-circuit events, helping protect connected circuits and equipment in compatible applications.
Whether you're maintaining a manufacturing plant, office building, school, municipal facility, or another property with legacy electrical equipment, the EB3040L provides the configuration and protection characteristics needed for compatible replacement applications. Built to last and designed to work within existing Type EB systems, it helps support the continued operation of electrical infrastructure that remains in service today.
