HD11F series photovoltaic knife switch offers several convenient features. Firstly, it solves the issue of difficult installation commonly associated with traditional knife switches by providing two installation options: rail and base plate. Secondly, it eliminates the need for for opening the cover when wiring, making the process easier. Additionally, the full copper parts are thickened and a fastening ring design is added to ensure tight contact and prevent looseness. Arc isolation plates can also be installed for added safety.

This switch is applicable to control circuits with AC 50Hz, rated voltage up to 400V, and a rated impulse withstand voltage of 6kV. It can be used as an infrequent manual connection and disconnection circuit, as well as an isolation circuit in the power distribution systems of household appliances and industrial enterprises. This greatly improves the personal safety protection performance and prevents accidental electric shock.

It complies with GB/T14048.3 and IEC60947-3 standards.
