Selamat Siang,
MX / XF / MN adalah istilah untuk Triping coil dari Circuit Breaker.
'- MN (Undervoltage Release) berfungsi men-trip MCCB ketika tegangan kontrol jatuh di bawah 0.35 x Un, artinya ketika terjadi drop tegangan secara signifikan atau total
- MX (Shunt Trip / Opening Release) berfungsi men-trip MCCB ketika tegangan kontrol mencapai lebih dari 0.7 x Un. Un (rated voltage) merupakan tegangan yang digunakan dalam pengoperasian MCCB
Biasanya pada Circuit breaker memiliki MX dan XF untuk Opening (Trip) dan Closing. MN ditambahkan jika ingin Trip saat tegangan kontrol dibawah tegangan normal untuk menjamin operasi opening / closing dari Circuit Breaker.
