The WIC1 is a CT supplied overcurrent relay with earth current monitoring. Due to the CT supply, no auxiliary voltage is required. It is suitable for harsh environments and operates in a temperature range of -40°C to +85°C. According to Woodward, the WIC1 can operate maintenance-free for a period of 20 years.
