RVB-S(RCW) Outdoor VCB

brief introduction

ROCKWILL have developed the RVB-S type of outdoor vacuum circuit breakers using modern processing technology and computer-aided design techniques, combined with the latest generation insulation technology and compact design make whole product light and save volume.RVB-S family switches have a range of models as follow:
_RVB-36S type is provided with rating current 800A maximum, and breaking current 20kA.
_RVB-24S type is provided with rating current 1250A maximum, and breaking current 25kA.
RVB-12S type is provided with rating current 1250A maximum, and breaking current 25kA.
_All above types switches is designed by mechanical and electrical life 10,000 times.
