The 0.16mH inductance and 3.13% voltage drop (UK) at rated current are sized to limit the rate of rise of voltage (dV/dt) and reduce motor bearing currents and reflected wave spikes on longer cable runs. ## Integration notes The reactor measures 0.21m wide by 0.17m tall by 0.12m deep — roughly the footprint of a small contactor or drive frame. The main circuit connects via free cable ends (no terminal block), so plan for a strain-relief point and a suitable lug or ferrule for the panel wiring. Total power loss is 54W (27W coil + 27W iron core), which needs to be considered in the enclosure thermal budget. Thermal class B insulation (130°C) per IEC 60085 gives standard headroom for continuous duty at a 40°C ambient. The EN 61558-2-20 compliance and UL/CSA recognition are noted on the label.","metaTitle":"Siemens SIDAC 4EP3910-7BS10 Output Reactor, 45A 4000Hz","metaDescription":"Siemens SIDAC 4EP3910-7BS10 output reactor, 3-phase AC, 45A max, 4000Hz switching frequency, 0.16mH, IP00, free cable ends.
