FNQ Series - 1332 x 1-12 500Vac maximum voltage time-delay supplemental midget fuses. Fiber tube construction. Nickel-plated brass endcaps. For superior protection, upgrade to FNQ-R Class CC fuses. Midget fuses are 13/32 x 1-1/2 cartridge fuses in a wide variety of volt and amp ratings to provide supplemental protection to industrial, commercial, agricultural, heating, ventilating and air conditioning equipment. Typical applications are motor control transformers and circuits with in-rush currents. Small size midget fuses often protect control circuit wiring, motor control transformers or small motors. The National Electrical Code (NEC) now requires more protection of these components creating an increased replacement demand for these fuses.
