Bel Fuse 0ZRA Radial Leaded PTC Fuses

Bel Fuse 0ZRA Radial Leaded Positive Temperature Coefficient (PTC) Fuses offer a 3A to 14A operating current range, 16VDC maximum voltage rating, and 100A maximum current. Similar to Bel's extensive line of traditional fuse products, these 0ZRA fuses protect against harmful overcurrent and short circuit conditions. They also protect against over-temperature conditions not necessarily caused by excessive current. These devices reset after power to the circuit is removed, the fault is cleared, and power is reapplied to the circuit. This reset ability protects electronic equipment, which remains fully functional, and eliminates the need to physically replace a fuse. Bel Fuse 0ZRA help protect valuable electronic systems and reduce warranty and service costs. The series is used in a range of industrial, computer, battery, consumer electronics, telecom, and automotive applications.
