Its 14% relative throttling factor and 0.0066 H inductance are sized for harmonic mitigation and line-side smoothing in drive and power-conversion applications. The 17.3 A rated current (19.2 A maximum) sets the continuous ampacity for the reactor under the specified 40 °C ambient. The 100 W power loss at full load must be dissipated within the enclosure — factor that into your thermal budget and cabinet sizing. The resonant frequency of 134 Hz sits well above the 50 Hz line frequency, so the reactor will not resonate with the fundamental. Thermal class B (130 °C) per IEC 60085 means the insulation system is rated for a maximum hot-spot temperature of 130 °C. This is the standard class for general-purpose industrial reactors and allows for a reasonable overload margin without derating. The 4EP4300-6MS00 carries a mature lifecycle stage from Siemens. This means it is an established, stable product that remains in the active catalog — not a new introduction and not flagged for discontinuation. The reactor measures 0.267 m wide by 0.221 m tall by 0.12 m deep. At IP00 it has no enclosure of its own, so it mounts directly to a panel backplate or chassis using the manufacturer's standard foot-mounting pattern. The screw-type terminals accept the main power conductors; verify wire gauge against the terminal capacity before terminating. The 100 W heat dissipation requires clearance around the core for natural convection or forced airflow in the cabinet.","metaTitle":"Siemens SIDAC 4EP4300-6MS00 Filter Reactor, 17.3A, 400V, 3-P","metaDescription":"Siemens SIDAC 4EP4300-6MS00 filter reactor, 3-phase, 17.3A rated, 400V, 50Hz, 14% throttling, IP00.
