Question

Can the parameters of the K2CA Over Current Relay be changed during actual use?

Answer



Yes, they can because the CT (current transformer) output will not open even when the operating current or operating time parameter is changed.
However, when lowering the parameter, make sure that the current input is not lower than the operating current parameter.
