EH34030 - 30 Amp Circuit Breaker

EH34030 - 30 Amp Circuit Breaker

Selecting the correct replacement circuit breaker means more than matching the amperage—it also requires compatibility with your existing electrical equipment. The EH34030 is a 3-pole, 30 Amp plug-on thermal-magnetic circuit breaker designed for use in compatible Type EH-4 electrical distribution systems. Whether you're replacing an existing breaker during scheduled maintenance or restoring service after an electrical fault, the EH34030 provides the form, fit, and function required for compatible legacy installations without altering the equipment's original design.

Its thermal-magnetic trip mechanism responds to both sustained overload conditions and instantaneous short circuits, helping protect branch circuits and connected equipment from electrical damage.
