Description

Designed for industrial circuit isolation, the Siemens 3VA5340-0BB31-0AA0 is a 3-pole, 400A molded case switch. As part of the Sentron 3VA5 frame family, it serves primarily as a disconnect rather than a standard breaker. This unit installs into Siemens 3VA panelboards and switchboards. It also functions as a direct replacement for legacy JXD63S400 switches. Lugs are not included. Rated for 65kAIC at 480VAC, it features an MCS110 self-protecting instantaneous trip unit.
