The 14% relative throttling factor and 0.0066 H inductance are designed to attenuate harmonics from non-linear loads such as variable-frequency drives and rectifiers, protecting upstream capacitors and transformers from resonance and overvoltage. The resonant frequency of 134 Hz places the anti-resonance point well below the 5th harmonic (250 Hz), which is the dominant harmonic from a 6-pulse drive — a common application for this class of reactor. The reactor measures 0.267 m wide by 0.221 m high by 0.12 m deep, with an IP00 protection class — meaning it has no enclosure and must be mounted inside a panel or cabinet that provides the required ingress protection. Connections are via free cable endings, so the installer provides the appropriate ring lugs or ferrules for the main circuit wiring. The thermal class B (130 °C rise) per IEC 60085 and an ambient temperature rating of 40 °C define the continuous-duty thermal limits; for audit purposes, the temperature rise must be verified against the actual load profile in the panel design. The lifecycle stage for the 4EP4311-0BP00 is recorded as mature. This indicates the product is in its established production phase — not newly introduced and not announced for discontinuation.","metaTitle":"Siemens SIDAC 4EP4311-0BP00 Filter Reactor, 3-Phase, 400V, 1","metaDescription":"Siemens SIDAC 4EP4311-0BP00 filter reactor, 3-phase, 400V AC, 50Hz, 12.5 kvar, 17.3A rated, 14% throttling, IP00.
