Rated 35.5 A continuous with a 39.5 A maximum, it operates at 415 V AC, 50 Hz, and delivers 25 kvar of reactive power. The 7 % relative throttling factor and 189 Hz resonant frequency mean it's designed to suppress the 5th harmonic (typically 250 Hz on a 50 Hz fundamental) and limit inrush current to the capacitor bank. The 1.7 mH inductance and Class H (180 °C) thermal insulation allow it to handle sustained harmonic currents without saturating the core. IP00 means it's an open-frame component — intended for enclosure mounting where the panel provides the environmental seal, not for standalone outdoor or washdown duty. This part carries a 'mature' lifecycle stage from the manufacturer — meaning it's in steady production, not newly introduced and not on a formal phase-out notice. No successor order code is published, so the BOM line stays on this MPN. For current pricing and availability, submit an RFQ; we source through independent distribution channels and confirm both at quote time. Same part, different passport — genuine is genuine, and we'll document the provenance. Dimensions are 0.16 m deep, 0.225 m wide, 0.21 m high — a compact footprint for a 25 kvar reactor. Terminals are flat connector / screw-type, sized for the 35.5 A continuous current. Mount it in the enclosure with clearance for magnetic field coupling to adjacent steel; keep ferrous structural members at least one core diameter away to avoid eddy-current heating. The open-frame design (IP00) means the enclosure must provide the IP rating your application requires. The 7 % relative throttling factor is the impedance at rated current relative to the line voltage — standard for detuned reactor banks that shift the resonant frequency below the 5th harmonic. At 189 Hz resonant frequency, this reactor is safe for use with capacitor banks in 50 Hz systems where the 5th harmonic (250 Hz) is present; it prevents parallel resonance between the bank and the supply transformer. The 25 kvar reactive power rating matches a capacitor bank of that size; pair it with a 25 kvar PFC capacitor and the combination stays detuned. Class H insulation (180 °C rated) gives headroom for the additional copper losses from harmonic currents. The 40 °C ambient temperature rating is the standard reference; derate for higher ambient or forced-air cooling requirements.","metaTitle":"SIDAC 4EU2532-0MH08-0AA0 Filter Reactor, 35.5A, 415V, 25 kva","metaDescription":"SIDAC 4EU2532-0MH08-0AA0 filter reactor, 3-phase, 35.5A rated / 39.5A max, 415V, 25 kvar, 7% throttling, 189 Hz resonant frequency, IP00, Class H.
