Jersey City, NJ [August 23, 2018] Bel Fuse-Circuit Protection, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of fuses, announces their latest Axial Lead Battery Strap PTC fuses, the 0ZSA & 0ZSC Series, which are designed for use in rechargeable battery packs, lithium cell and battery packs. 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.

Bel’s low profile, low resistance, solid state resettable PTC fuses are resistance spot welded to the battery cells or to the battery pack interconnect straps. Other features include an operating (high hold current) range of 1.1 - 7.3A and maximum voltage of 12V - 30VDC. These fuses have been investigated for use in safety circuit 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 amps within 5 seconds, per the ANSI/NFPA 70, “National Electrical Code”. Bel’s fuses carry the cURus certification mark for both the U.S. and Canada, are TUV Certified (R50105187), RoHS 2 compliant, lead free and halogen free.
