Bel Fuse-Circuit Protection has released their latest Axial Lead Battery Strap PTC fuses, the 0ZSA and 0ZSC Series. The devices are intended for use in rechargeable battery packs, lithium cell and battery packs. These fuses can be used in a mixture of applications, such as battery packs for computers, mobile radios, mobile phones, cordless phones, camcorders, PDAs and power tools.
These low resistance, low profile, solid-state resettable PTC fuses are resistance spot welded to the battery cells or the battery pack interconnect straps. Other features comprise an operating (high hold current) range of 1.1-7.3A and a maximum voltage of 12V-30VDC. These fuses have been examined 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 restrict the current to 8A within five seconds, per the ANSI/NFPA 70, ‘National Electrical Code’. The company’s fuses carry the cURus certification mark for both the US and Canada, are TUV Certified (R50105187), RoHS 2 compliant, lead-free and halogen-free.
