Filter Reactor for Harmonic Mitigation
The Siemens 4EU2732-0EB18-0BA0 is a 3-phase filter reactor rated at 50 kVAR at 525 V, 50 Hz, with a 7% detuning factor. This places it squarely in the harmonic mitigation chain for power-factor-correction capacitor banks — the 7% detuning shifts the resonant frequency to 189 Hz, keeping it clear of the 5th and 7th harmonics common on 6-pulse drives. The IP00 enclosure means it's intended for cabinet or panel mounting, not standalone outdoor duty. Terminals are screw/flat-type, sized for the 50 kVAR throughput.
We source the 4EU2732-0EB18-0BA0 to order against an RFQ.
Deployment Context
Mount this reactor between the capacitor bank and the bus in a power-factor-correction panel. The 7% detuning protects the capacitors from harmonic overloading — a standard choice for industrial networks with variable-frequency drives. The screw/flat-type terminals accept lug or busbar connections typical of 50 kVAR-class components.
