NRP Series PC Board Circuit Protectors Higher economic efficiency than a fuse SIL subminiature circuit protectors adopting IC terminal arrangements, and mountable directly on PC boards Simple construction and high performance. Unlike fuses, the thermal trip mode (bimetal) eliminates erroneous interruption due to inrush currents. Rated current can be selected to meet the load. Circuits with high inrush currents can be protected against over- loads (unlike fuses). Reusable 200 operations (tripping at 200% the rated current) with higher economic efficiency, and less mainte- nance than fuses. Available in slim and flat styles. Slims (can be mounted on PC boards by using pick and place machines). Available in non-sealed and sealed types. With the sealed type, cleaning after soldering is possible. With a manual OFF mechanism, convenient for circuit checkups This product is recognized by Underwriters Laboratories Certification Organization / Applicable Standard Mark under UL1077 as aSupplementary Protector File No. UL recognized UL1077 File No. E68029 CSA C22.2 No. 235 CSA file No. LR65560 For details, see the list of standard certified products in the back of this catalog.
