<p>The panel has a drive unit (32) introducing drive movements in each switching pole (25, 28, 30). The poles are connected with bus bar connectors (3-5) by controllable contact systems (9, 10, 11), where the contact systems are controlled such that conductive connection is formed between the switching poles and the bus bar connectors by each controllable contact system. Each switching pole forms a conductive connection between the bus bar connectors and a grounding contact (31) in a closed condition.</p> |
