Littelfuse 242 Series Barrier Fuses are designed for overcurrent protection in intrinsic safety applications. These fuses offer high interrupting ratings and are available in both axial lead and surface mount versions. The 242 fuses provide a reliable solution for hazardous location barrier circuits, with a range from 40mA to 250mA. These devices meet agency approvals and provide a minimum opening time of 4 hours at 100% rating, with quick response times at higher current levels. The 242 series fuses are suitable for intrinsic safety protection in hazardous location equipment, electrical connections, and test equipment.
