UNIQUE BREAKERS UBIZ UBIZ2020 2 POLE 20 AMP TANDEM CIRCUIT BREAKERS UBIZ

Description:

The UNIQUE BREAKERS UBIZ2020 (Type UBIZ) is a tandem (twin) 20A/20A circuit breaker used in legacy Zinsco and Sylvania load centers to provide two independent 20-amp circuits within a single breaker slot. It is commonly installed in residential panels where space is limited and additional circuits are required. Electricians and maintenance personnel use this breaker for repair, retrofit, or replacement to maintain circuit protection in older electrical systems.

Applications:

The UBIZ2020 tandem breaker is widely used in residential electrical panels for branch circuits such as lighting, receptacles, and small appliance loads. It allows two 120V circuits in one space, making it ideal for panel expansion without adding new breakers. It is specifically designed for Zinsco/Sylvania panels and serves as a replacement for models like R3820 and RC3820.
