EB2040L - 40Amp Circuit Breaker

EB2040L - 40Amp Circuit Breaker

If you're maintaining an existing electrical system that uses EB-series breakers, finding the correct replacement is critical. The EB2040L is a 40 Amp, 2-pole thermal-magnetic circuit breaker designed specifically for compatible EB panelboards manufactured before 1989, helping preserve the original configuration of your electrical distribution equipment.

Built to provide dependable protection against overloads and short circuits, the EB2040L combines thermal and magnetic trip technology in a single breaker. The thermal element responds to sustained overcurrent conditions, while the magnetic mechanism reacts quickly when fault currents occur. This design helps protect connected circuits while maintaining the operating characteristics expected in compatible legacy installations.

The breaker features a 10kA interrupting capacity at 120/240VAC, a non-interchangeable trip unit, and comes equipped with both line and load terminals for installation in approved applications. Rated for operation in ambient temperatures up to 40°C, the EB2040L is well-suited for facilities that continue to rely on established electrical infrastructure. Whether you're replacing a failed breaker during maintenance, refurbishing electrical equipment, or keeping an older panel in service, this breaker is designed to deliver the form, fit, and function required for compatible EB systems while being built to last.
