RC3820 - 20Amp Circuit Breaker

RC3820 - 20Amp Circuit Breaker

When it's time to replace an RC3820 circuit breaker, getting the right fit is essential. This 20 Amp, 2-pole Type RC38 replacement circuit breaker is made to fit the same location as the original RC38-20, making it a practical choice for maintaining compatible electrical panels already in service. Built with a space-saving plug-on design, this breaker installs in the existing position without requiring changes to the panel when used in compatible equipment. The thermal-magnetic trip mechanism helps protect branch circuits by responding to both overloads and short circuits, while the 10kA interrupting rating at 120/240VAC makes it suitable for a wide range of residential, commercial, and light industrial applications. Whether you're replacing a breaker during routine maintenance or restoring an existing electrical panel, this replacement is built to last and provides the form, fit, and function needed for compatible RC38 installations.
