Product Information

Full details

The Schneider Electric TeSys Vario V1 is a three-pole disconnect switch base unit designed for motor control applications. It offers a key benefit of safe and reliable isolation for motors up to 11kW at 400V AC-23 and can also handle DC switching. A caveat is that a separate handle assembly is required for operation. This base unit is a foundational component for building robust manual motor disconnect switches.

Extended Product Information

FAQs

What is the main purpose of this product?

This is a base unit for a disconnect switch, primarily used to provide safe manual isolation of motor circuits in industrial applications.

Does this unit include a handle?

No, the handle assembly is sold separately and must be purchased to operate the disconnect switch.

What is the maximum power this switch can handle?

It is rated for motor applications up to 11kW at 400V AC-23.

Can this switch be used for DC circuits?

Yes, it features DC switching capability up to 250V DC-1 to DC-5 using series-connected contacts.

How is this unit mounted?

It can be mounted on a standard 35mm DIN rail or directly to a panel using screw fixings.

What does the IP20 rating mean?

The IP20 rating indicates protection against solid objects larger than 12.5mm (like fingers) and signifies no protection against water. It is suitable for dry, protected indoor environments.

Can I add auxiliary contacts to this unit?

Yes, the base unit supports up to 4 additional modules, which can include auxiliary contacts for signaling purposes.

Troubleshooting

Switch does not operate

Verify that the rotary handle assembly is correctly installed and engaged with the switch base. Check for any obstructions preventing the mechanism from moving.

Overheating at terminals

Ensure all power and motor cables are securely tightened at the screw terminals. Check that the connected load does not exceed the rated capacity of the switch (32A/690V or 11kW at 400V AC-23).

Unit fails to isolate power

Confirm the unit is wired correctly and that the handle is in the 'OFF' or 'O' position. Inspect for internal damage to the contacts. This unit is designed for manual disconnection and should be used in conjunction with appropriate circuit protection devices.

Pros and Cons

Pros

  • Robust construction for industrial environments.
  • Versatile DC switching capabilities alongside AC.
  • Modular design allows for expansion and customization.
  • Supports common mounting methods (DIN rail and screw).
  • Reliable isolation for motor circuits.

Cons

  • Requires a separate handle assembly to function as a switch.
  • IP20 rating means it's not suitable for exposed or outdoor environments without additional enclosure.
  • Primarily a base unit, requiring additional components for full functionality.

Setup, Compatibility & Care Instructions

Setup:

  1. Mount the base unit onto a standard 35mm DIN rail or using screw fixings.
  2. Connect the motor and supply power cables to the designated screw terminals.
  3. Attach the required rotary handle assembly to the front of the base unit (sold separately).
  4. If needed, install up to four additional modules (e.g., auxiliary contacts) onto the designated slots.

Compatibility:

  • Compatible with Schneider Electric TeSys Vario rotary handle assemblies.
  • Suitable for DIN rail (35mm) or panel mounting via screws.
  • Designed for use with motor loads up to 11kW at 400V AC-23.
  • Supports DC switching up to 250V DC-1 to DC-5.

Care:

  • Keep the unit clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents.
  • Periodically inspect terminal connections for tightness and signs of corrosion.
  • Ensure the handle mechanism operates smoothly and engages correctly with the base unit.
