The 7 % relative throttling factor and 0.0037 H inductance shape the harmonic profile at the line input; the 227 Hz resonant frequency means it traps the 5th harmonic (300 Hz on a 60 Hz fundamental) and attenuates higher-order ripple. Reactive power of the filter bank is 12.5 kvar. Thermal class B (130 °C rise) per IEC 60085 keeps the winding temperature within limits at the rated 40 °C ambient. Power loss runs 73.6 W at full load — plan for that heat inside the enclosure. Dimensions are 0.219 m wide × 0.179 m high × 0.123 m deep; the footprint fits a standard backplate, but the 0.123 m depth eats into the gland-plate clearance. Terminals are screw-type and tab connections on the main circuit — torque to the manufacturer's spec for the lug size you choose. No DIN-rail clip; it bolts directly to the mounting surface.","metaTitle":"SIDAC 4EP3901-3MS00 Filter Reactor, 480 V 60 Hz 15.6 A","metaDescription":"SIDAC 4EP3901-3MS00 3-phase filter reactor, rated 15.6 A at 480 V 60 Hz, 7% throttling, 12.5 kvar, IP00.
