FU-32 Clamp On CT

The FU-32 is an indoor clamp-on split core current transformer. The manufacturer's category page lists 700g weight, 32mm core, 60 to 600A at 5A or 1A. A shop parameter table for the same model gives nominal primary currents 100, 150, 200, 300, 400, 500 and 600A, ratio 400:5 or 200:5 (customizable), accuracy 0.2%, 0.5% or 1%, system voltage 720V, output 10mA to 200mA AC or 333mV AC or 100mV to 2V, frequency 40 to 500Hz, dielectric strength 3kV at 50/60Hz for 1 minute, standard 2.5m cable, CAT II or CAT III 600VAC, maximum jaw opening 32mm, dimensions 110 x 130 x 41mm, weight 700g, operating minus 25C to plus 55C, 0 to 85% relative humidity non-condensing, and altitude below 3500m. These shop figures are stated here as the shop listing's figures.

Applications listed for this model include energy sub-metering, power meters, power quality monitoring, HVAC and pumps, and distributed measurement.

Item and specification

How to select

Choose the FU-32 when an indoor clamp-on CT with a 32mm jaw is needed for sub-metering or power quality monitoring. Check the conductor diameter against the 32mm jaw, the primary current against the nominal list, the output type against the meter or monitor input (current, millivolt or voltage output), and the accuracy class against the measurement use.

Before payment, confirm the model, the jaw size, the ratio, the output type, the quantity, and the delivery terms. Ask for the current datasheet to be confirmed in writing before ordering. No price, minimum order or lead time figure is stated here; confirm each in writing with your inquiry.

Records and comparisons

Keep a record for every test this instrument performs. A useful record states the instrument model, the device under test, the test settings, the results, the date, and the person who ran the test. Records of that form can be checked months later, when a result is questioned or a device is retested after repair. A record that only says pass or fail cannot be checked, and a test that cannot be checked will eventually have to be repeated.

When comparing this model with a neighbouring model from the same family, compare the same items for both: the test functions, the ranges, the accuracy class, the display and output features, and the standards referenced. A comparison that uses one model's headline figures against another model's detailed figures is not a comparison. Ask for the current datasheet for each model under consideration, and compare datasheet against datasheet.

If the instrument will be used by more than one person, agree who owns the test records and where they are kept before the first test. Shared instruments with private records produce results that cannot be checked by anyone except the person who ran the test, which defeats the purpose of keeping records at all.

What to confirm before ordering

Before payment, confirm the model, the specification from the current datasheet, the quantity, the price, the lead time, and the delivery terms, in writing. Ask in your inquiry to confirm the payment terms, the trade terms, and the reply time you should expect, rather than assuming any of them. No price, minimum order or lead time figure is stated on this site.

Notes

No warranty period is stated on this page, because the reference material does not give a company-site warranty figure for this model.
