Advantages of the W199 Power Relay
The Magnecraft 199 relay is the powerhouse open relay. Standard parts can handle up to 40A
and there are options to handle up to 50A. The device is available in a variety of configurations
and coil voltages. Available with up to two poles, double and single throws, insulated and non-
insulated double make and/or break, and several switching forms. Options include auxiliary 10A
switches with quick connects or screw terminals, quick connects on the coils and/or contacts,
tungsten stationary contacts, fine silver contacts, pressure wire connectors on the output terminals
and blowout magnets near the contacts for high voltage DC switching.
