Changeover switch SIRCOVER 250A, 4P, I-0-II

SIRCOVER devices are manually operated changeover switches with positive indication of the contact open position. They are designed for open-transition transfer (I–0–II) and are available in 3- or 4-pole versions. They enable on-load transfer between two power sources in any low-voltage supply circuit and ensure safe electrical isolation through double contact breaking on each pole. Other applications facilitate changing power-source polarity or phase sequence (e.g. reversing motor rotation) and earthing.
