R3850 - Duplex 50/50 Circuit Breaker

R3850 - Duplex 50/50 Circuit Breaker

The R3850 is a 50 Amp duplex thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for legacy electrical distribution systems that utilize Type R38 circuit breakers. This space-saving plug-on breaker allows two independent circuits to occupy a single breaker position, making it a practical solution for maintaining existing panel configurations without altering the panel layout. Built to last and manufactured to meet applicable industry standards, this replacement breaker provides dependable overcurrent and short-circuit protection for your compatible residential and light commercial electrical systems. Designed specifically to fit the original installation location of the R38-50, it offers an easy replacement option for maintaining the safe operation of existing equipment while preserving compatibility with legacy panelboards. Its thermal-magnetic trip mechanism helps you protect wiring and connected equipment by responding to both prolonged overloads and instantaneous short-circuit conditions, giving property owners and electricians confidence when servicing compatible electrical systems.
