"...How to set the basic threshold setting in relay M.B.C.H? It can be adjusted from 10% to 50%In, with 10% steps"
Please advise:
1. what type (i.e. current, voltage, frequency, power, impedance ... operated) relay is it ?
2. what do you mean M.B.C.H? What is their full name.
3. Are you in the IEC or IEEE world ?
