It operates on 50 to 60 Hz mains, so it covers both standard industrial line frequencies without derating. The 11.6% voltage drop is the key sizing parameter: it defines how much the choke limits inrush current and harmonic distortion on the line side of a drive or converter. At 0.518 m wide, 0.318 m deep, and 0.565 m tall, this is a large-frame choke — expect dedicated floor-mount or heavy sub-panel space, not a DIN rail clip. IP00 means no enclosure protection: the choke requires installation inside a cabinet that provides the environmental seal. The flat-connector main terminals are sized for bus-bar or large-lug cabling, not spring-cage terminations. ## Thermal and lifecycle reality Rated for 45 °C ambient with thermal class H insulation — the winding can handle a 180 °C hot-spot, which gives headroom in a warm cabinet but still demands the 2440 W coil loss and 795 W iron-core loss be ventilated out. ## Sourcing and fit confirmation The 680 A / 690 V rating pins the choke to large-drive applications. The 0.00018 H inductance and 11.6% voltage drop are the numbers to match against your drive manufacturer's recommended line reactor spec.","metaTitle":"Siemens 4EU5051-0AA10-0C Mains Choke, 680A, 690V, IP00","metaDescription":"Siemens 4EU5051-0AA10-0C mains choke (Netzdrossel). 680 A, 690 V AC, 50-60 Hz, 0.18 mH, IP00, thermal class H.
