Zinsco Sylvania R38 RC38 R3830 1 Pole 30 Amp 120 240V Tandem Circuit Breaker

Description:

The Zinsco / GTE Sylvania R38 / RC38 / R3830 is a 30 Amp tandem (twin) circuit breaker designed for legacy Zinsco and Sylvania load centers. It provides two independent circuits in a single breaker space, allowing efficient panel space utilization. Electricians and maintenance personnel use this breaker for repair, retrofit, or replacement in older electrical panels where tandem configurations are required.

Applications:

The Zinsco R38-30 breaker is widely used in residential electrical panels for branch circuits such as lighting, receptacles, and small appliance loads. Its tandem design allows two 30A single-pole circuits in one unit, making it ideal for panel expansion without increasing panel size. It is specifically designed for Zinsco/Sylvania systems and is commonly found in older installations.
