Three phase Breaker error external

Does anyone can help me with this type of error?

"Value must be a 1x2 vector of numeric type in which the second element is larger than the first and may be Inf". I don´t know how this could be, because I just have one magnitude input (it does'nt work with complex neither).

As far as I'm concerned, the multimeter, directly in the breaker should work.

Hi Santiago,

Can you share the Simulink model for the same?
