Schneider Electric Contactors in Oman | TeSys Deca LC1D Guide

Schneider Electric TeSys contactors are widely used for motor switching and control-panel applications. Correct selection starts with the load, utilization category and control voltage—not only the ampere number printed in the reference.

How to select a contactor

For a motor application, start with the motor nameplate information and the intended duty. The control circuit must also be checked because the coil-voltage suffix changes the complete contactor reference.

• Motor rated current and power
• Utilization category and switching duty
• Main supply voltage
• Control/coil voltage
• Required auxiliary contacts and accessories

Understanding LC1D references

Within the TeSys Deca family, references such as LC1D09, LC1D12, LC1D18, LC1D25 and LC1D32 represent different contactor ratings. The suffix is important because it identifies the coil configuration.

• Do not order from LC1D09 or LC1D25 alone
• Provide the complete suffix, for example M7, B7, U7 or N7
• For replacement work, photograph the existing nameplate

Contactor and overload coordination

A contactor is only one part of a motor-control arrangement. The overload relay, short-circuit protection and coordination requirements should be considered together for the actual application.

Common references to search

Use these references as starting points in the Al Qarar catalogue. Final selection, availability and pricing are confirmed by quotation.

Frequently asked questions

Can I replace one LC1D coil voltage with another?

Only when the control circuit is designed for that coil voltage. Confirm the full reference before replacement.

Is the ampere rating alone enough to select a contactor?

No. Application duty, utilization category, motor/load data and coil voltage also matter.

Can Al Qarar quote from a part number only?

Yes. For straightforward references, send the complete part number and quantity. For replacements or uncertain references, include a nameplate photo.
