Product Description
The Zinsco R38-20 is a 20/20 Amp twin tandem circuit breaker designed for compatible Zinsco electrical panels and load centers. Its space-saving tandem design provides two independent 20 Amp, single-pole circuits in one compact breaker unit.
The R38-20 is easily identified by its two red toggle handles, which correspond to its 20 Amp circuit ratings. Each toggle operates an independent 20A circuit. The breaker features a plug-on connection and is commonly used as a replacement for existing Zinsco R38 tandem breakers in older electrical panels.
This is an original-style Zinsco R38-20 breaker and should be matched carefully to the existing breaker and panel before ordering. Zinsco R38 breakers are discontinued legacy products and are no longer manufactured by the original manufacturer.

Condition

Important Compatibility Information
The R38-20 is a tandem breaker with two independent 20A single-pole circuits. It should not be confused with the Zinsco RC38-20, which is a 2-pole configuration with tied handles.
Before ordering, verify the R38-20 part number, 20/20A rating, red toggle configuration, physical size, mounting connection, and panel compatibility against the breaker being replaced. Do not select a replacement breaker based on amperage alone.
