It carries 40 A maximum continuous current with 0.00035 H inductance and 2 % voltage drop at rated conditions. The IP00 open-frame construction requires enclosure mounting. Screw-type terminals handle power connections, and thermal class B insulation keeps the core and coil within safe limits at 40 °C ambient. The 2 % voltage drop at rated current indicates the choke is sized for moderate harmonic mitigation without excessive voltage headroom loss. Power loss splits into 41.8 W in the coil and 11.4 W in the iron core. That heat must be evacuated from the enclosure. Dimensions are 0.178 m wide, 0.153 m high, and 0.105 m deep. The IP00 design requires clearance for airflow and creepage distances inside the cabinet.","metaTitle":"Siemens 4EP3700-5US00 Mains Choke, 3-Phase 40A, 0.35mH","metaDescription":"Siemens 4EP3700-5US00 mains choke for VFD, 3-phase AC, 40A max, 0.35mH, 2% voltage drop, IP00, screw terminals.
