Description
Restoring power in older properties requires exact-fit components like this 70A two-pole breaker. It delivers thermal-magnetic protection for 120/240V circuits while maintaining original panel specifications. This unit mounts into legacy Zinsco and Sylvania load centers, serving as an authentic alternative to the UBIZ270 substitute. Electricians appreciate the straightforward plug-on installation. Featuring a 10kA interrupting rating, the HACR-rated design safely handles HVAC equipment loads.
