What makes an auto-reset MCB different from a standard MCB?
A standard MCB requires manual resetting after a fault. An auto-reset MCB like the WARD3100C will automatically restore supply after under-voltage conditions are resolved, saving time and reducing site visits.
Does this device include PME protection?
Yes. It provides PME fault protection, meaning no earth rod is required for most EV charger installs.
When does the unit require manual reset?
After over-voltage trips, the device must be reset manually to ensure safety and compliance with wiring regulations.
Is this product suitable for EV and solar applications?
Yes. The WARD3100C is specifically suited to EV charging and solar installs where voltage monitoring, automatic reset, and PME fault protection are critical.
