3 Amp Resettable Fuse with YINT 60V 300

A 3 A hold solution for power and control circuits up to 60 V

YINT 60V-300 is the primary product for customers requesting a 3 amp resettable fuse with a 3.00 A hold-current rating. The radial through-hole PPTC also provides a 6.00 A trip-current rating and a 60 V maximum voltage.

This page focuses on where that combination fits: 24 V control equipment, DC power inputs, small motor branches and other circuits that need a recoverable current limiter with useful voltage headroom.

YINT 60V 300 Product Data

The active 60V-300 has a published maximum current of 40 A and maximum power dissipation of 2.80 W. Its time-to-trip reference is 8 seconds maximum at 15 A under the stated test conditions. These values let an engineer check the actual overload rather than relying on the 3 A product label.

The component is supplied as a radial DIP part for through-hole assembly. It fits power sections where a leaded device and the required board spacing are acceptable.

Using 60V 300 on a 24 V Control Rail

A 60 V device can provide useful rating margin on a nominal 24 V rail. The measured rail, switching overshoot and external surge must still stay below 60 V. If the installation can produce a higher transient, the designer should add appropriate voltage protection or evaluate the 72V-250, which has a 72 V maximum rating but a lower 2.50 A hold current.

For PLC accessories, control panels and sensor power branches, the 3 A hold rating should exceed the hottest continuous load after derating. Cable and connector ratings should also match the protected branch.

Motor and Inrush Current Checks

A motor may draw several times its running current during startup and a much longer high current during stall. Capture both waveforms on the real hardware. A suitable 60V-300 application lets valid startup complete while forcing a sustained stall toward the high-resistance state before the motor wiring exceeds its thermal limit.

Power inputs with large bulk capacitors require the same type of check. Charging current duration, source impedance and ambient temperature determine whether the PPTC rides through the event.

Nearby YINT PPTC Options

The model comparison helps customers move in the correct direction when the initial 3 A request changes. Select 72V-250 for lower hold current and greater voltage headroom, keep 60V-300 for the defined 3 A hold point, or consider 30V-500 when the system voltage is lower and the desired trip rating is 10 A.

The comparison is a shortlist, not a substitution statement. Each model requires its own resistance, temperature and time-current review.

Product Selection Summary

Ordering and Sample Evaluation

For a fast YINT recommendation, identify the normal current at the highest internal temperature, startup peak and duration, maximum fault current, rail voltage and available through-hole area. Include the protection goal, such as cable protection, motor-stall limiting or input-branch protection.

Test samples in the finished enclosure at hot load and during the intended fault. Record voltage drop, trip time and recovery so purchasing receives a model that has already passed the application conditions.

FAQ

1. Which YINT model has a 3 A hold rating?

YINT 60V-300. Its published trip rating is 6 A and its maximum voltage is 60 V.

2. Is 60V-300 suitable for nominal 24 V equipment?

It can be evaluated when all operating and transient voltages remain within 60 V and the current, temperature and fault conditions also meet the datasheet.

3. What is the trip-time reference for 60V-300?

The product page lists a maximum of 8 seconds at 15 A under the stated conditions. Use the complete curve for the actual overload.

4. What if the circuit needs more than 60 V?

YINT 72V-250 offers a 72 V maximum rating with 2.50 A hold and 5.00 A trip. Confirm whether the lower hold current fits the load.

5. Can 60V-300 pass motor startup current?

That depends on the measured peak, duration and temperature. Compare the startup waveform with the time-to-trip curve and verify it on the final assembly.

6. How is 60V-300 mounted?

It is a radial through-hole PPTC intended for DIP assembly.

Conclusion

YINT 60V-300 gives the 3 amp resettable fuse search a concrete product answer. Its 3 A hold, 6 A trip and 60 V ratings suit many power and control branches when derating, inrush and fault current are verified. Customers needing a different electrical window can compare 72V-250 and 30V-500 before requesting samples.
