Transport/storage/packaging Transport to the Remove accessory pack and store safely in the packaging for later installation. installation site Due to the low weight, no lifting eyes are provided. The vacuum contactor can be lifted and transported without tools. The fastening eyelets (*) can be used for lifting with a crane.
Transport/storage/packaging Storage Note During transport and storage, the vacuum contactor must be in the following con- dition: • OPEN switching position • Unlatched condition (only if unlatching is available). Note Risk of corrosion damage if stored improperly! The vacuum contactor can be stored for up to a year in its transport unit if the stor- age conditions listed below are met.
The operating instructions are an integral part of the switching device and contain all information for commissioning and use. The basic version and all listed configurations of the vacuum contactors 3TM are type-tested devices as per IEC 62271-1 (see also “Standards”, on page 10)
3TM vacuum contactors operate in continuous, periodic, and short-term operation. Suitable for high frequency of operation and unlimited on-time. Intended use Vacuum contactors 3TM are suitable for switching any type of alternating current cir- cuits under normal operating conditions, such as: •...
General information Type approval as per the German X-Ray Ordinance The vacuum interrupters installed in the switching devices are type-approved as sources of interference radiation according to § 8 of the German X-Ray Ordinance and they comply with the requirements for sources of parasitic X-ray emitters ac- cording to Annex 2 No.
