W0508RB12 Westcode - Diode
W0508RB12 Description
Rated at 1200 V and 508 A, the Westcode W0508RB12 is a thyristor (SCR). Common uses are AC switches, soft starters, DC drives and controlled rectifiers in industrial power equipment. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.
