They ensure switching transfer of sources or transfer of two low voltage circuits on load as well as their safety disconnection. These switches are extremely durable and are tested and approved for use in the most demanding applications, such as resitive load or total system applications. Advantages Stable positions SRCOVERs have three stable positions which are not affected by voltage drops or vibrations, thus protecting your load against network interference. On load switching The SRCOVER UL enables secure and reliable switching, without the need for pre-breaking upstream. Compact design The Sircover are based on a back-to-back switching technology, providing a compact solution. 3 General Catalogue 13-14

The handle interlocking function prevents the user from opening the door of the enclosure when the switch is in the "ON" position. Opening the door when the switch is in the "ON" position is possible by defeating the interlocking function (Not S5 and V handles) with the use of a tool (authorized persons only). The interlocking function is restored when the door is re-closed. acces_151_a_1_cat acces_1_a_1_cat acces_152_a_1_cat acces_286_a_2_cat Shaft for external handle Handle Length Length Dimension Dimension Rating (A) type (in) (mm) X (in) X (mm) Reference 1...
