WIC1+WIB1+WIP1 Accessory: Flag Indicators

WI1 SZ4, see separate page

Flag indicator, for a mechanical trip signaling independent of external (auxiliary) voltages.

WI1 SZ5, see separate page

Flag indicator, for a mechanical trip signaling independent of external (auxiliary) voltages, including a bistable signal contact 230 V AC, 3 A.

Benefits and Key Features

  • CT/Self-powered – No auxiliary supply voltage needed

  • Designed for harsh environment

  • Compact form factor


Application

  • The WI Line devices are self-powered – The protection relay does not need supply voltages for Ring Main Units (RMUs).

  • The primary application of WI Line devices is Feeder Protection (also as backup) that does not need supply voltage.
