Eaton / Westinghouse EB3100 – 100A 3 Pole Molded Case Circuit Breaker Next Day Delivery

Part of the legacy E-Frame family, the Eaton EB3100 delivers thermal-magnetic overcurrent protection for commercial and industrial electrical systems. This three-pole, 100-amp unit features a bolt-on mounting configuration designed for older infrastructure. It installs into vintage Westinghouse enclosures and Eaton Pow-R-Line C panelboards without requiring aftermarket adapters. Rated for 10kAIC at 240VAC, it serves as an exact fit substitute for aging components, often replaced by the EHD3100.
