LGB3B060B - 60Amp Circuit Breaker

LGB3B060B - 60Amp Circuit Breaker

Working on an existing panelboard often means finding a breaker that matches a very specific set of requirements. The LGB3B060B is a 60A, 3-pole LGB G-frame circuit breaker designed for compatible low-voltage panelboard applications. It uses a thermal-magnetic trip unit and is rated 65 kA at 480Y/277V and 14 kA at 600Y/347V. When you're identifying a functional replacement, the 60A rating is only one part of the equation. Pole count, frame, interrupting ratings, lug configuration, conductor range, and physical dimensions should all correspond with the equipment. Checking those details together helps determine whether the LGB3B060B is the right form, fit, and functional match for the panelboard you're servicing.

Where It Works Best

The LGB3B060B 60A 3-pole circuit breaker is particularly useful for maintaining existing and legacy low-voltage panelboards that call for this specific LGB G-frame configuration. In these applications, compatibility comes from matching the complete breaker specification—not simply locating another 60A, three-pole device.
