WARTD263-100 is a 2 pole A-type 100mA time delay RCD designed for use where two RCDs are installed in series and discrimination is required. Its built-in time delay helps ensure the upstream device only trips when appropriate, allowing the downstream protective device to operate first during a fault.
This makes it well suited to distribution arrangements where selective coordination is needed, including installations connected to EV systems and solar or renewable applications. As an A-type device, it provides residual current protection for AC and pulsating DC components.
Installer Tip: Time delay RCDs are generally used in upstream positions only. They should be selected as part of a coordinated protection strategy where discrimination between devices is required.
