Product Description
Raising the Standard in Electric Meter Test Equipment
The Model 335 load box accessory is a revolutionary new electric meter test equipment accessory that complements the already versatile 3 Series. By utilizing a Model 335 with a 3 Series, users can perform phantom load meter testing up to 5A while implementing the new current harmonic waveforms from ANSI C12.20. In addition, this accessory will give the user the ability to perform a CT burden added test along with the 3 Series exclusive burden measurement test. Its compact size allows the 335, the 3 Series, and all standard accessories to be stored in the same carrying case. With the added functionality of the 335, the lightweight 3 Series is truly a step above.
