Description
Serving as a legacy 3-pole, 80A molded case circuit breaker from Siemens, the REF3B080 provides essential long-time and instantaneous (LI) trip functions. Built for commercial applications, it maintains safety in aging electrical systems. Designed with a bolt-on mounting style, this E-frame breaker installs into classic Siemens and I-T-E panelboards. It acts as a cross-reference for older EF3B080 units and is officially replaced by the modern ED63B080. The unit features a 14 kAIC rating at 480V.
