The 0.267 m width and 0.221 m height fit a standard 600 mm deep enclosure, and the 0.12 m depth leaves room for the fan plenum or bus bars behind it. Terminals are screw-type and tab connections for the main circuit, so you'll need a lug kit or ring terminals sized for the 28.9 A feed. ## Thermal class and power loss Thermal class B per IEC 60085 means the winding insulation is good for a 130 °C hot-spot rise. The reactive power of the filter bank is rated at 20 kvar, which lines up with the 7% detuning for a typical 30–50 kVA drive.","metaTitle":"Siemens SIDAC 4EP4300-5MS00 Filter Reactor, 28.9A / 400V / 7","metaDescription":"Siemens SIDAC 4EP4300-5MS00 3-phase filter reactor, 28.9A rated, 400V AC, 7% detuning, 0.0019H, IP00.
