EB2020L - 20Amp Circuit Breaker

EB2020L - 20 Amp Circuit Breaker

The EB2020L circuit breaker is a 20 amp, 2-pole thermal-magnetic breaker designed for use in electrical distribution panels manufactured prior to 1989 that require the EB frame type. Built to provide dependable circuit protection in legacy electrical systems, this breaker interrupts overloads and short circuits in 120/240VAC applications with a 10k A.I.C. interrupting rating. Its thermal-magnetic trip mechanism combines thermal protection for prolonged overload conditions with magnetic response for short-circuit events, helping safeguard wiring and connected equipment. The EB2020L includes both line and load terminals, simplifying installation and ensuring proper connection within compatible panelboards. Rated for operation at 40°C, this breaker is built to last and serves as a form-fit-function replacement where EB-style breakers are required in older electrical distribution equipment.
