Siemens NGB3B100B – 100A 3 Pole Molded Case Circuit Breaker Hot Picks

Providing 100A of thermal-magnetic protection, the Siemens NGB3B100B is a 3-pole MCCB for commercial facilities. Unlike the standard NGB3B100, this model includes factory-installed load side lugs for immediate wiring. This unit bolts into Siemens P1, P2, and P3 panelboards. As an NGB frame breaker, it serves as an exact replacement for older systems, though Siemens recommends the 3VA51 series for new builds. It delivers 100kAIC at 240VAC and 25kAIC at 480Y/277VAC, and is HACR rated.
