EHB2020 - 20Amp Circuit Breaker

EHB2020 - 20Amp Circuit Breaker

When you're maintaining an existing electrical distribution system, using the correct replacement breaker matters. The EHB2020 is a 2-pole, 20 Amp Type EHB thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for compatible equipment. Built for use in electrical panels manufactured before 1989, it provides the electrical ratings and physical compatibility needed to help keep legacy systems operating as originally designed.

The EHB2020 combines thermal overload protection with magnetic short-circuit protection, helping safeguard connected circuits against common electrical faults. Its non-interchangeable trip unit preserves the factory-set trip characteristics, making it a dependable choice when replacing an existing breaker in compatible installations.
