Zinsco RC38AL30 Tandem Circuit Breaker 30A Type RC38 2P 120 240V Green

Description:

The Zinsco RC38AL30 is a tandem (thin) molded case circuit breaker designed for Zinsco load centers, providing overcurrent protection for 120/240V circuits. It combines two poles into a single breaker space, allowing efficient use of panel capacity. This breaker interrupts power during overloads or short circuits and is typically used as a replacement in legacy Zinsco electrical systems.

Applications:

The Zinsco RC38AL30 breaker is used in residential and light commercial panels to protect circuits supplying 240V loads such as water heaters, small HVAC systems, and appliances. Its tandem design allows installation in panels with limited space, making it common in older Zinsco installations where additional circuits are needed.
