Overview
Relay Protection Relay NJB1-X Relay (Three-Phase Unbalance, Phase Sequence, Phase Failure Protection) 1.
General NJB1-X relay (hereinafter called relay) are applied in AC380V~480V control circuits at a frequency of 50Hz/60Hz as protection elements of phase sequence, phase failuire and phase unbalance,making or breaking circuits.
The relay with the true effective value of three phase AC voltatage provides more reliable operating protection.
The products meet the requirements of standard IEC 60947-5-1.
