Emirel V3-19 is a three-phase voltage relay designed for over/under-voltage protection, featuring independent delays for each threshold. The ±20 % adjustable window allows tight control around the system’s nominal voltage, while front LEDs identify which limit has been exceeded.
Features
- Overvoltage VM and undervoltage Vm supervision for 3-phase mains
- Independent delay timers: TM for VM and Tm for Vm (0.5 to 30 s)
- Model A with Vn selector for 380/400/415 VAC; self-powered input
- Form C output relay (2 CO), 5 A @ 230 VAC; high endurance
- LED diagnostics: ON (green), AM VM alarm (red), Am Vm alarm (red)
