Adjustable Voltage & Current Protector 63A (140–300V, DIN Rail)
A DIN-rail protector that cuts power when your mains voltage or current goes out of a safe range, then reconnects automatically once it is stable again.
In areas with unstable supply this is what stands between a voltage spike and your fridge, TV, AC or computer. The digital display shows live voltage and current, and the upper/lower voltage limits, current limit and reconnection delay are all adjustable.
Key features
- Over-voltage and under-voltage protection (140–300V adjustable)
- Over-current protection up to 63A
- Live digital voltage and current display
- Automatic reconnection with adjustable delay (1–600s)
- Standard DIN-rail mount for your distribution board
Note: this connects to 220V mains wiring — have it installed by a qualified electrician.
