Square D VZ20 Auxiliary Contact Block Module

Product Description

The SQUARE D VZ20 is an auxiliary contact block module designed to expand the switching and control capabilities of enclosed motor starters. It adds two auxiliary contacts to the starter assembly, allowing for additional control circuit functions such as interlocking, signaling, or status indication. The module mounts directly to compatible enclosed starter units and is sized for clean integration within the enclosure. Licensed electricians and industrial controls technicians typically handle installation and wiring of this accessory in panel and motor control center applications.

The VZ20 is used with TeSys enclosed starters installed in VCF and VBF enclosures. It is suited for industrial and commercial motor control applications where additional contact points are needed for control logic, remote status monitoring, or safety interlocking circuits. The compact form factor, measuring 3.5 inches in length, 2.2 inches in width, and 1.5 inches in height, fits within the existing enclosure footprint without requiring additional panel space.
