Key specifications
Rated current: 4A
Rated voltage: 400VAC / 250VDC
Fuse size: D01
Characteristic: gG (full-range protection)
How to use
To install the fuse, ensure that the power supply to the circuit is completely disconnected. Insert the fuse link into a compatible D01 fuse base or holder, ensuring it is seated firmly. Once installed, the fuse base cover or cap should be tightened according to the manufacturer's instructions to ensure proper contact and safety. Always verify that the circuit load does not exceed the 4A rating before restoring power.
What to consider before purchase
Verify that the current rating of 4A matches your circuit requirements.
Ensure your existing fuse base is compatible with the D01 size.
Check that your system voltage does not exceed 400VAC or 250VDC.
Confirm that the gG characteristic is appropriate for your specific application.
Usage recommendations
Always replace a blown fuse with one of the exact same rating and type. Never attempt to bypass or repair a fuse, as this poses a significant fire and safety risk.
