It is built to EN 61558-2-20, the standard for chokes and reactors, and terminates via screw connections. The 12.5 % p impedance is the key selection parameter: it defines the voltage drop at rated current and the harmonic attenuation the reactor provides. At 400 V, 50 Hz, a 12.5 % p choke is typically used in drive input circuits to limit current spikes and reduce harmonic distortion — it is not a tuning reactor for a specific harmonic order. The 12.5 kVAR figure gives the reactive power compensation capability; match it to the total kVAR of the downstream capacitor bank or drive DC bus. The 40 /H thermal class (TA/ISOKL:40 /H) indicates a 40 K temperature rise at rated load, which is standard for this class of iron-core reactor. This reactor sits between the mains supply and a variable-frequency drive or a power converter, typically on the line side. It attenuates conducted EMI, limits inrush current during capacitor charging, and provides some protection against line notches and transients. The screw terminals accept standard ring or fork lugs; mounting is via the chassis base inside a panel or enclosure.","metaTitle":"Siemens 4EU2432-0AJ08-4BA0 Filter Reactor, 12.5 kVAR, 400 V,","metaDescription":"Siemens 4EU2432-0AJ08-4BA0 filter reactor, 3-phase, 12.5 kVAR, 400 V, 50 Hz, 12.5% p, IP00, screw terminals.
