EH34020 - 20 Amp Circuit Breaker

EH34020 - 20 Amp Circuit Breaker

When it's time to replace a circuit breaker in an existing electrical system, getting the correct fit matters just as much as matching the electrical ratings. The EH34020 is a 3-pole, 20 Amp plug-on thermal-magnetic circuit breaker designed for use in compatible Type EH-4 panelboards and electrical distribution equipment. Whether you're maintaining a commercial facility, industrial operation, or institutional building, this breaker provides the form, fit, and function needed to help keep your existing system operating as intended.

Its thermal-magnetic trip design responds to both prolonged overloads and sudden short circuits, helping protect branch circuits and connected equipment from electrical faults.
