LGB2B070B - 70Amp Circuit Breaker Description
LGB2B070B - 70Amp Circuit Breaker
The LGB2B070B is a 70A, 2-pole LGB G-frame circuit breaker made for compatible low-voltage panelboard applications. Inside is a thermal-magnetic trip unit, with interrupting ratings of 65 kA at 480Y/277V and 14 kA at 600Y/347V. If you're tracking down a breaker for an existing panel, those numbers are important—but don't overlook the details around them. A proper match also means checking the LGB frame, two-pole configuration, load-side lugs, conductor range, and breaker dimensions against the equipment you're servicing.
