Three phase chokes - compensation reactance (ELEKTROKOV, a. s. ZNOJMO)
| 12 | THREE PHASE CHOKES - compensation reactance | SV PR |
Three-phase protection chokes for capacitor battery 3x440V in distribution network 3x400V with 3EI lamination, covering IP00 (p=7 %, freq=189Hz). Inductance tolerance +/-2 %. The chokes include thermal cut-off 130°C, 250V, 2,5A.
We design chokes with another parameters (other than parameters in table below) after consultation with out technical department.
