The Siemens 3VA9263-0QC50 is a spreader link (broadened busbar connector) accessory designed for SENTRON 3VA20, 3VA21, and 3VA22 MCCBs with 100A, 160A, and 250A frame sizes. The accessory increases the pole-center distance of MCCB terminals, making busbar and cable connections easier while improving electrical clearances inside distribution panels. The set includes 3 spreader links and 2 phase barriers for enhanced insulation and installation safety.
This accessory is widely used in MCC panels, PCC panels, switchboards, and industrial power distribution systems where additional terminal spacing is required for simplified wiring and busbar termination.
