Filnor Inc products

Type A, single-throw and double-throw, non-fusible knife switches have a corrosion resistant finish, are mounted on GPO-3 bases and have high clips and hinges. The high clips and hinges simplify the front-of-board connections. Available 30 Amp thru 2000 Amp.

Construction: All current carrying parts of Type D knife switches are milled and provided with a corrosion resistant finish. Designed for back-connection, these switches are furnished without bases for mounting on insulating panels for customers’ switchboards. Switches rated 1200 amperes and larger are shipped on throw-away bases as standard. Prices will be quoted upon request for switches, rated 800 amperes and smaller, mounted on throw-away bases.

When a drive unit is attempting to rapidly brake a motor “Deceleration Braking Cycle” or when an “overhauling load” condition exists, the spinning motor acts as a generator.

Filnor vehicle disconnect switches typically range from 400 amps through 2000 amps and voltage up to 2000 volts DC. The switch is typically housed in a fiberglass enclosure. Filnor manufactures switches for light and heavy rail transit vehicles.
