Product Description

The Zinsco Q-20 is a 20 Amp, 1-pole, 120V Type Q circuit breaker designed for use in compatible Zinsco electrical panels and load centers. This plug-in breaker is commonly used as a replacement for existing Zinsco Q-20 / Q20 breakers in legacy Zinsco electrical systems.

Before ordering, verify the Zinsco manufacturer, Q-20/Q20 part number, 20A rating, 1-pole configuration, physical size, and connection style against your existing breaker and panel.

This is a legacy Zinsco replacement breaker. Do not select a replacement breaker based on amperage or handle color alone.
