1SBN030110R1000

The ABB VE5-1 Mechanical and Electrical Interlock Unit is designed to interlock two compatible ABB contactors. Its mechanical mechanism prevents one contactor from closing while the other is closed, helping avoid simultaneous operation in switching arrangements that require the contactors to operate one at a time.

The VE5-1 also has two built-in normally closed (NC) auxiliary contacts for electrical interlocking. When wired into the relevant control circuit, these contacts provide an electrical interlock between the contactors alongside the mechanical interlock. The unit is identified by ABB part number 1SBN030110R1000 and is listed for compatible A9–A40 contactors in horizontal mounting arrangements.

The mounting rail or plate is not supplied, so check the required mounting method and the exact contactor combination before installation.
