Description
Part of the Series G family, the EGS1020FFB is a 1-pole, 20A molded case circuit breaker built for commercial and industrial applications. It provides reliable thermal-magnetic protection with an 85kAIC rating at 240V and 35kAIC at 277V. This EG-frame breaker mounts into Eaton Pow-R-Line panelboards using a secure bolt-on connection. As the Series G line is phasing out, this unit is slated to be replaced by the Power Defense PDG11M0020TFFB, making it ideal for maintaining existing systems.Specifications
