Wire Wound Resisitors
Features:
The design of wire grid, lends, itself to various advantages over
conventional cast iron grids & standard wire wound resistors
assemblies. In the assembly design breakable parts are exclude,
resulting in robust construction . In the wire grid assemblies, the
unique terminal arrangement, facilities easy replacement of individual
grid. The assembly can be tailor designed & its available in stack
& panel mounting versions This is ideal for compact deign of special
purpose control panels . The panel mounting version has an added
advantage of saving in interconnection & wiring
Application: Load bank, rotor starter , crane controllers, motors starting & braking resistors
