The CH4-24kV reverse-mounted contact boxes and CHJ14-24kV three-way contact boxes are advanced epoxy-resin insulated modules engineered for 24 kV switchgear systems. Their fully enclosed design and precision molding guarantee safe, stable current transmission while simplifying installation in compact or multi-angle configurations.
Built to excel in harsh environments, these contact boxes maintain mechanical and electrical integrity across a wide temperature span and high elevations. The CHJ14 three-way variant further enhances system flexibility by enabling multiple outgoing connections, making this family ideal for demanding industrial and utility applications.
