Recall of Dielle YK78 Model Residual Current Device (RCD)
A range of Residual Current Device (RCD) have been recalled by the supplier due to a risk of electrical fire and electric shock.
The affected RCDs can be identified by the brand name 'Dielle', the model number 'YK78' and the invalid approval marking of N.21905. These markings can be found on the product as per the above photographs.
The recall includes all rated models in the range 6A,10A,16A, 20A, 25A and 32A with these markings.
The affected models were supplied nationally from 2006 onwards
Risk of fire and electric shock
The RCD may not comply with the product safety standard, and may not trip reliably under an earth fault condition. Marking N.21905 is not a valid Approval number.
Building owners, managers and electrical contractors are urged to check switchboards or load centres for potentially affected RCDs.
The recalled product must be replaced with an alternative RCD that has a valid approval mark.
If you find a recalled RCD model installed in a customer's premises, you must notify them about the recall and explain the product type has been shown to not reliably operate in fault situations and so should be replaced by a licensed electrical contractor. The supplier is no longer trading and unfortunately, this generally means the cost to remediate falls back to the person in control of the building or person conducting a business or undertaking (PCBU).
