LBS series: Striker mechanism is employed in which the striker opens the switches automatically when the fuse blows.
LB series: Wide variation is available by combining each unit’s functions and the combination is easy to rearrange.
FUJI air load break switch type LBS is provided with current limiting power fuses and type LB is not so fitted. Both types are compact and incorporate arc-extinguishing devices of FUJI’s own design. The arc is drawn into a long narrow chamber with close clearances in which the gases are rapidly cooled and dispersed. Contact points therefore wear very slowly, so giving switches a long service life. FUJI air load break switches are recommended for use with power capacitors and transformers.
