New Uni-T UT61 series (UT61e+)

<< < (23/31) > >>

Wytnucls:
Burden voltage will be comparable to a glass fuse (~8mohm for a 13A fuse).
Safety wise, not much better than a very fast FF glass fuse rated for 250VAC, in a CAT II home environment.
There is no data for higher AC voltages or any DC voltage.

A multimeter which respects European/US regulations should have fast fuses rated for AC and DC, with the proper voltage rating and breaking capacity.

Less arc flash?

Wytnucls:
I couldn't shatter a glass fuse put across the mains, so arc flash is unlikely at mains voltage and in a CAT II environment.

A BS1362 dissipates close to 1 watt at nominal AC current, so may cause some damage in a multimeter at higher currents.
The fuse will last for at least 30 minutes at 1.6x nominal current.
The purpose of the fuse is to protect the cable insulation when the appliance becomes faulty (3A fuse if appliance draws <700W, otherwise 13A)

AsianFuse AF63C-10A in UTC61E+ is not fuse like "on the order of billions in use."

As stated it's a BS1362 fuse. I have.. something approaching a hundred of them around the house. There are 28 million households in this country and I can't even be bothered to look up commercial properties. There are absolutely billions of this size of fuse.

The UT161E is claiked to be third party certified, so it may have the proper fuses or is properly rated.

I would love to see a teardown but, at hefty 129 Euros, it is quite a steep price.

The Batronix website has more info than the manufacturer's

Perhaps consider adding these meters (61E+/161E) to the spreadsheet?
