Description
Supplied without standard load lugs, this 60A thermal-magnetic MCCB utilizes a nut keeper plate for connections. It achieves a 100kAIC interrupt rating at 240VAC and 25kAIC at 480Y/277VAC, providing robust overcurrent protection for commercial facilities. Designed to bolt into Siemens P1, P2, and P3 panelboards, it operates within the SENTRON GB/GG frame lineup. It serves as a reliable component that is eventually replaced by the 3VA5160-4ED24-0AA0. The device is HACR and reverse feed rated.Specifications
