Product Details

1204‑TFB2 is Rockwell Allen‑Bradley motor terminator.

It is installed at motor terminals,specially used for long‑distance motor cable occasions,effectively suppress high‑voltage reflected‑wave spike generated by PWM output,prevent motor insulation damage caused by voltage overshoot. Maximum allowable inverter carrier frequency is 2kHz,comes with 3‑meter prefabricated connecting cable. Improper matching will cause motor insulation aging,over‑temperature and motor damage,widely used for old‑site drive‑motor system overhaul and spare‑part replacement.
