EMI Three-Phase Filters

As a leading supplier of three-phase filters, our filters are designed to perform in both commercial and industrial environments.

Our three-phase filters are rated up to 480VAC/250VAC and 600VAC for both Delta and WYE configurations. Current ratings are available up to 2500A. Single, dual, and multi-stage designs are available for specific needs. Versions rated at higher current and voltages can be offered upon request. 

Typical applications for these EMI/EMC/RFI filters include three-phase industrial drives, inverters, controllers, frequency converters and industrial machine tools. Other applications include industrial power supplies, UPS, fixed computer systems (mainframes), MRI's and X-Ray equipment, heavy duty industrial equipment, and more. 

Our three-phase EMI filters carry US(UL), Canadian (cUL/CSA), and European (IEC/VDE/Semko) agency approvals and are available in both general purpose and low leakage current medical versions. At our agency approved 'in-house' test facility, US, Canadian and/or European safety approvals can be obtained quickly and cost effectively on any of our customized and custom products, if requested.
