NRP Series PC Board Circuit Protectors Higher economic efficiency than a fuse SIL type subminiature circuit protectors adopting IC termi- nal arrangements, and mountable directly on PC boards Simple construction and high performance applying a pos- itive load reversing mechanism by IDEC s original design Unlike fuses, the thermal trip mode (bimetal type) elimi- nates 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 cur- rent) with higher economic efficiency, and less mainte- nance than fuses. Available in slim and flat types. Slim types (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 Certification Certification Organization Applicable Standard This product is recognized by Underwriters Laboratories Mark File No. under UL1077 as aSupplementary Protector UL1077 UL File No. E68029 CSA C22.2 No. 235 No. LR65560 For details, see the list of standard certified products in the back of this catalog.

The rated current can be corrected according Temperature Correction Curve Sensors to the Temperature Correction Curve. The rated current is based on an ambient temperature of 25C. Since a thermal tripping method is employed, the rated current should be corrected according to the ambient temperature with reference to Control Stations the curve shown below.
