RV 53 Load Break Switch assemblies for OEM

The RV 53 load break switch assemblies feature DA or DP drive mechanisms and housing with mimic diagram directly mounted onto the switch. The compact assembly can be directly mounted into medium voltage switchgear.

RV 53 is a three-position SF6 gas insulated “sealed for life” load break switch with integrated earth. Its “built to last” design with double seals is maintenance free. The concept is safe and robust. It is focused on reliable operation during the full life time of medium voltage switchgear. It features an integrated earth. The switch enclosure consists of two half-shells in high quality epoxy material. The shell design features isolating epoxy walls that protect phases from flash over.

DA is a double spring drive mechanism for operator independent switching between open, closed or earthed position of the RV switch in incoming/outgoing functions.

DP is a three spring drive mechanism for operator independent switching. It is designed for use in combination with fuses.

DA and DP have standard integrated functional interlocks to prevent incorrect operations.

DA and DP are fit to receive plug & play accessories to cover a wide range of applications.
