Two panel mount fuseholder designs are available for supplementary or Class CC branch circuit protection. Class CC fuses have a rejection feature on one end cap which mates with the rejection feature of Littelfuse Class CC fuse blocks and fuseholders to prevent the installation of fuses with lower voltage ratings or interrupting ratings. **APPROVALS:** Recognized under the Components Program of Underwriters Laboratories and Certified by CSA. ## **SPECIFICATIONS:** **Electrical:** Rated at 30 amperes for any voltage up to 600 volts. **Dielectric Strength:** 4000 volts minimum. **Mounting:** Flange mounting either in front of or behind panel. Watertight version must be front panel mounted. Maximum panel thickness is .75". **Molded Parts:** Black thermoplastic (UL94 V-0). **Knob:** Screw type, with engraved markings: unfilled characters ( **571** 007, **571** 008, **571** 007P, **571** 008P), light blue characters ( **571** 027, **571** 028, **571** 027P, **571** 028P). **Terminals:** Brass. Tin-plated. Combination solder and[1] /4" QuickConnect. Side terminal has .125" diameter hole. Bottom terminal has .156" x .124" elongated hole. **Ambient Temperature:** –40°C to +85°C. **Hardware: 571** 007, **571** 008, **571** 027, **571** 028, **571** OCC, and **571** RCC, none; **571** 007P, **571** 008P, **571** 027P, **571** 028P, **571** OCCP, and **571** RCCP, two O-rings for watertight seal per MIL-PRF-19207. *** Please refer to Fuseology section for information on proper fuseholder de-rating.** **==> picture [174 x 93] intentionally omitted <==** **----- Start of picture text -----**
