It features a holding current of 1.00 A and a trip current of 2 A, with a maximum voltage rating of 277 VAC. The device has a maximum rated current of 10 A and an initial resistance of 1.1 Ohms. It operates within a temperature range of -20°C to +85°C and includes a power dissipation rating of 2.9 W. Physical dimensions include a length of 16.3 mm, width of 1.9 mm, and height of 21.7 mm, with a lead spacing of 10.2 mm.

Ptc Resettable Fuses Feature Summary

• Provides automatic resettable overcurrent protection using polymer positive temperature coefficient technology.
• Capable of handling high fault currents up to the maximum rated limit without permanent damage.
• Designed for through-hole PCB mounting with radial leads for secure mechanical attachment.

Ptc Resettable Fuses Applications

• Protection of AC mains circuits in consumer electronics
• Overcurrent safeguarding in industrial control systems
• Circuit protection for telecommunications equipment

Ptc Resettable Fuses Procurement Notes

Verify that the component matches the specific 0ZRV series designation and holds the required UL and TUV certifications for your target market. Confirm that the 277 VAC voltage rating aligns with your system's line voltage requirements. Ensure the radial lead pitch of 10.2 mm fits your PCB footprint constraints. Check RoHS compliance status if restricted substances are prohibited in your assembly process.

Ptc Resettable Fuses Selection Notes

Select this component when AC line voltage protection is required rather than DC applications. The 1.00 A holding current suits moderate load protection needs. Consider the higher resistance compared to low-resistance series if voltage drop is a critical design factor. Evaluate the thermal environment to ensure operation remains within the specified -20°C to +85°C range under all expected conditions.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRV series, which specializes in radial leaded PTC devices for AC line protection. Unlike the 0ZRA or 0ZRS automotive-grade series, this model targets general AC applications. It differs from surface-mount options like the 0ZCG series by offering through-hole installation capabilities suitable for higher current handling in larger packages.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1.00 A holding current, 277 VAC rating, and radial package style. Verify that any alternative maintains equivalent trip characteristics and physical dimensions for board compatibility. Cross-reference certification approvals to ensure regulatory compliance in the end application.
