Automatically monitors the supply voltage on both 400 & 415V supplies without the need for any manual dip switch settings. Within 5 seconds in the event of an under-voltage of any phase less than 207V or an over-voltage of any phase more than 253V, live, neutral and earth will be isolated.
Following an under-voltage, isolation will automatically reset when normal operating range is restored.
Following and over-voltage, isolation, on the grounds of safety, will require a manual reset. (press the red button of the WP9 to reset.)
We can also now offer a 63A version:
WARB5100C/PME63RDSP - 100A MCB + PME RELAY 63A RCBO/SPD
