For In setting of 30mA, the time delay is fixed to 0 (instantaneous) and is not adjustable (i.e. any other time delay cannot be selected when 30mA is set). 2. The unit is factory set to 30mA trip and instantaneous delay. Adjustment of these settings can be INSTALLATION Installation work must be carried made if necessary to suit the requirements of the installation.
