Schneider Electric VZ20 Auxiliary Contact Block

Description:

The Telemecanique VZ20 auxiliary contact is an auxiliary contact block used with TeSys Vario switch disconnectors to provide additional signaling and control contacts in industrial electrical control systems. Commonly installed in motor control centers, industrial control panels, power distribution assemblies, and machine isolation circuits using TeSys Vario disconnect switches. Maintenance teams, OEMs, and system integrators use this auxiliary contact block for equipment replacement, control circuit expansion, retrofit projects, and switch disconnector upgrades.

Applications:

The Telemecanique VZ20 auxiliary contact block is used to extend the auxiliary signaling capabilities of TeSys Vario switch disconnectors in industrial automation systems. It is commonly found in motor control panels, conveyor systems, manufacturing equipment, packaging machines, HVAC control panels, and power distribution systems where additional normally open auxiliary contacts are required for interlocking, status indication, and control circuit monitoring.
