The thermal class B insulation (130 °C continuous) and 50 °C ambient rating mean it handles moderate thermal stress without derating, typical for line-reactor applications in motor drives or power supplies where you need to limit harmonic current or smooth voltage notches. Mounting dimensions: 0.219 m wide by 0.179 m tall by 0.143 m deep. That depth is the critical panel clearance dimension — make sure your enclosure depth leaves room for the screw-terminal connections on the front face. The IP00 rating means no integral enclosure; plan for a gland plate or busbar entry point in the panel.","metaTitle":"Siemens 4EP4010-0WS00 3-Phase Reactor, 1.03A, IP00, 50°C","metaDescription":"Siemens 4EP4010-0WS00 3-phase reactor, rated 1.03A, thermal class B, IP00, screw terminals, 50°C ambient.
