A Manual Transfer Switch lets an operator switch a load between two power sources, typically utility and standby generator. Transfer happens by hand, with mechanical interlocking that prevents both sources being connected at the same time.

Schneider Electric's TransferPacT range provides manual transfer with mechanical and electrical interlocks, in changeover or three-position (closed-open-closed) configurations.

FAQ

Frequently asked questions

What is a Manual Transfer Switch (MTS)?

An MTS lets an operator switch a load between two power sources, typically utility and standby generator. Transfer happens by hand, with mechanical interlocking that prevents both sources being connected at the same time.

What is the maximum current rating of NLC's MTS?

NLC's Manual Transfer Switches are rated up to 3200 A.

What operating configurations does the MTS offer?

It offers changeover or three-position (closed-open-closed) operation, with both mechanical and electrical interlocking, based on Schneider Electric's TransferPacT range.

Can the MTS be locked in position for safety?

Yes, it is padlockable in any position and can be fitted with optional auxiliary contacts for status indication.

When is a manual transfer switch the right choice?

Typical applications include small commercial buildings, workshop and warehouse standby supply, sites where manual control is preferred, and maintenance bypass for ATS systems.

How does the interlocking prevent paralleling the two sources?

The MTS uses both mechanical and electrical interlocking, which prevents the utility and generator supplies from being connected at the same time during a manual changeover.

Can the MTS serve as a maintenance bypass for an ATS?

Yes. One of its typical applications is maintenance bypass for ATS systems, allowing the load to be transferred by hand while automatic equipment is serviced.

How do I request a configured manual transfer switch from NLC?

Send us your project specifications, including the current rating and number of poles required. Our power engineers will respond with a configured proposal based on the Schneider Electric TransferPacT Manual range.
