Description
Serving as an exact fit for commercial electrical systems, the ET100-315 delivers thermal-magnetic trip functions for 15A circuits up to 600VAC. It mounts into legacy ITE and Siemens F-Frame panelboards, making it an ideal solution for maintaining older infrastructure. While superseded by the F3B015 for new builds, this unit provides a seamless replacement. Rated at 25kAIC at 240VAC, it handles typical fault currents effectively and includes load side lugs for 14-10 AWG conductors.Specifications
