Bel Fuse's 0ZSA and 0ZSC series axial lead battery strap PTC fuses are designed for use in rechargeable battery packs, lithium cell, and battery packs.

Bel’s low profile, low resistance, solid state resettable PTC fuses are resistance spot welded to the battery cells or the battery pack interconnect straps. Other features include an operating (high hold current) range of 1.1 A to 7.3 A and a maximum voltage of 12 V_DC to 30 V_DC. These fuses have been investigated for use in safety circuits, and are suitable as a limiting device with nickel-plated straps (weldable terminals to the battery leads). They have also been calibrated to limit the current to 8 A within 5 seconds, per the ANSI/NFPA 70 National Electrical Code. Bel’s fuses carry the cURus certification mark for both U.S. and Canada, are TUV Certified (R50105187), RoHS 2 compliant, lead-free, and halogen-free.

These fuses can be used in a variety of applications, such as battery packs for mobile phones, computers, cordless phones, mobile radios, camcorders, PDAs, and power tools.
