100A Single Phase Automatic Reset Device with Built-In PME Fault Protection
Whitecliffe Electrical WARD3100C
The WARD3100C Single Phase Automatic Reset Device is engineered to provide top-tier safety by complying with BS: 7671 2018, Amendment 1: 2020 for TN systems. With PME fault protection built-in, this device monitors supply voltage and will completely disconnect live, neutral, and earth if a fault is detected, ensuring the safety of the entire electrical system.
The WARD3100C handles a 100A current and automatically responds to under-voltage or over-voltage events. For under-voltage, it automatically resets once the voltage returns to normal. However, for over-voltage, the device requires manual reset by switching the toggle to the “ON” position for added safety. This device is ideal for installations where no earth electrodes are required and offers additional overload and short-circuit protection.
