Description

Built to isolate electrical circuits safely, this 100A three-pole F-frame device functions purely as a non-automatic disconnect. It lacks thermal-magnetic overcurrent protection, making it ideal for manual switching. The unit mounts securely into vintage Westinghouse panelboards using standard bolt-on connections. It acts as a seamless drop-in substitute for obsolete FDB3100 and FD3100 components. Rated for 600VAC and 250VDC networks, it incorporates high instantaneous withstand capabilities.
