Description

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.

  • Use as part of a coordinated upstream/downstream protection design
  • Apply the recommended terminal torque of 2.5Nm
  • Verify correct device coordination during design and commissioning
FAQs

What is a 100mA time delay RCD used for?

It is typically used where two RCDs are installed in series and upstream discrimination is required, so the downstream device trips first during a fault.

Is WARTD263-100 suitable for solar or EV installations?

Yes. The catalogue identifies this time delay RCD range as suitable for solar and EV applications where coordinated protection is required.

Is this a 2 pole device?

Yes. WARTD263-100 is a 2 pole A-type time delay RCD rated at 63A with 100mA sensitivity.

Does this device provide surge protection?

No. This is a time delay RCD only. Surge protection must be provided separately where required.

What is the size of WARTD263-100?

The dimensions are 36 x 82 x 70mm.
