Product FAQs
5 answersWhat original Zinsco part number does the UBIZ0245 replace?
This breaker is a direct cross-reference and replacement for the legacy Zinsco RC3845 circuit breaker.
What frame type is the UBIZ0245 built to?
It is built to the RC38 frame type, which is commonly referred to as the Zinsco Thin Series.
What panels accept the UBIZ0245 breaker?
It is designed exclusively for Zinsco Type RC load centers. It will not fit standard plug-on panels from other manufacturers due to the proprietary busbar connection.
Is the UBIZ0245 safety certified for use in legacy panels?
Yes, this Connecticut Electric replacement breaker is ETL listed and tested to meet current UL and ANSI safety standards for use in older Zinsco load centers.
Are there any special installation requirements for Zinsco replacement breakers?
When installing the plug-on connection, electricians should inspect the existing panel busbar for signs of pitting, corrosion, or heat damage, which are common in legacy Zinsco load centers. The breaker must make a secure connection to the busbar to function safely.
