The Schneider Electric TeSys VZ11 is a side-mountable auxiliary contact block designed for integrators and electricians seeking to enhance control and monitoring in automation systems. Its key benefit is providing reliable 1NO (make) contact functionality with a 32A rating, ensuring robust circuit operation. A minor caveat is its specific side-mount design, which may influence placement in extremely compact enclosures.

The VZ11 provides an additional electrical contact (1NO) that can be used to signal the status of a main device, such as a switch disconnector, or to control other circuits based on the state of the main device.
It utilizes screw clamp terminals, which are suitable for connecting both solid and flexible cables securely.
The VZ11 is designed to operate reliably within a temperature range of -20°C to 50°C.
Yes, the VZ11 is designed for use in both AC and DC applications.
It is rated for a durability of 30,000 electrical cycles and 100,000 mechanical cycles.
It is part of Schneider Electric's Green Premium program, indicating it contains recycled or recyclable materials and complies with specific environmental standards.
It is designed for integration with Schneider Electric TeSys VARIO switch disconnectors.
Verify wiring connections to the screw clamp terminals. Ensure the main device (e.g., switch disconnector) is functioning correctly and has reached its fully open or closed position. Check that the auxiliary contact is properly snapped onto the main device.
Re-tighten the screw clamp terminals. Ensure the correct size of wire is used and is securely gripped by the clamp.
Check wire gauge suitability for the current being carried. Ensure terminals are tightened properly. If the issue persists, the load may exceed the contact's rating, requiring a different auxiliary contact or relay.
Ensure the ambient temperature is within the specified operating range of -20°C to 50°C. If operating outside this range, consider alternative solutions or environmental controls.
Setup: The VZ11 is designed for side mounting, typically onto compatible Schneider Electric TeSys VARIO switch disconnectors. Ensure the main device is de-energized before installation. Slide the auxiliary contact block into its designated mounting slot on the side of the switch disconnector until it clicks into place. Connect wires to the screw clamp terminals, ensuring proper stripping of the cable ends and tightening of the screws for a secure connection.
Compatibility: This auxiliary contact block is primarily designed to integrate with Schneider Electric TeSys VARIO switch disconnectors. It is suitable for both AC and DC applications.
Care: The VZ11 requires minimal maintenance. Periodically check terminal connections for tightness. Clean the exterior with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners. Ensure the operating environment does not exceed the specified temperature range (-20°C to 50°C).
