That means during the installation of the Smartmeter for a 35A main fuse the reference value would be parametrized to 35A. The reference value for the power limit is also determined by this parameter. The reference value for a single-phase power limit is determined by the formula “Reference current x 230”, the reference value for a three-phase power limit is determined by the formula “Reference current x 230 x 3”.
