ZINSCO RC38-20 U 20A 240V 2P

Description:

The Zinsco RC38-20 U is a tandem (twin) circuit breaker designed for residential and light commercial electrical distribution systems. It provides overcurrent protection for 120/240V circuits and allows two circuits to occupy a single breaker slot, maximizing panel space. Commonly used in Zinsco load centers, it delivers thermal-magnetic protection for branch circuits and is typically installed as a replacement in legacy electrical panels.

Applications:

The Zinsco tandem circuit breakers are commonly used in residential and light commercial electrical panels where space-saving circuit protection is required. Typical applications include branch circuit protection, panelboard upgrades, and power distribution systems where reliable overcurrent protection and efficient use of panel space are critical.
