GXS Automatic Synchronizing Relay

GXS Automatic Synchronizing Relay

The Type GXS11B is an automatic synchronizing relay that has a fixed angle closing characteristic. It includes an instantaneous cup type unit, a time delay induction disk type unit and a telephone type auxiliary unit, case size M-1. The GXS12A relay is similar in construction to the GXS11 except with modified internal connections and the relay is used primarily for high- speed synchronism checking.
