Schneider Electric TeSys Giga LC1G High-Power Contactor

Overview

The Schneider Electric TeSys Giga LC1G High-Power Contactor is engineered for switching large AC motors and heavy electrical loads where standard TeSys Deca contactors reach their rated current limit. For panel builders and OEMs across Oman and the GCC, the TeSys Giga LC1G delivers the switching reliability of the wider TeSys family scaled up to the high-power motor control centers found in oil and gas, cement, and desalination plants.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the Schneider Electric TeSys Giga LC1G High-Power Contactor high-power AC contactor for heavy motor switching to industrial, commercial, and utility customers across the Sultanate of Oman and the wider GCC. Units are supplied on request with full technical documentation and application support for panel builders and facility engineers in Oman specifying a high-power AC contactor for heavy motor switching.

Operating Principle

The TeSys Giga LC1G contactor uses an electromagnetic coil to pull its main contacts closed against spring pressure whenever the coil is energized, establishing a low-resistance connection between the supply and the motor across all three phases simultaneously. When the coil is de-energized, the spring mechanism opens the contacts rapidly and consistently, interrupting motor current cleanly even under the high inrush currents typical of large motor starting.

Because motor starting current can reach several times full-load current for a brief period, the Schneider Electric TeSys Giga contactor’s contact and arc-extinguishing design is engineered to withstand repeated high-current making and breaking without excessive contact erosion, extending mechanical and electrical life in duty cycles with frequent starts common on pumps, compressors, and conveyor drives across Oman’s industrial sector.

Engineering Design of the Schneider Electric TeSys Giga LC1G

The TeSys Giga LC1G is built with a robust molded housing sized for its high current rating, with front or rear power terminal options to suit different motor control center bus layouts, and coil terminals arranged for straightforward control wiring. Auxiliary contact blocks and mechanical latching accessories can be added to the base contactor for interlocking and status feedback in reversing or star-delta starter configurations.

Coil control on the Schneider Electric TeSys Giga LC1G is available across a range of AC and DC voltages to match the control philosophy of the motor control center, and electronic coil control options reduce inrush current draw on the control circuit itself when multiple large contactors are switched simultaneously. The contactor’s mounting footprint is designed to integrate directly with TeSys Giga overload relays and circuit breakers for a complete motor starter assembly.

Key Features

The Schneider Electric TeSys Giga LC1G High-Power Contactor is built around design priorities that matter most to high-power motor switching specifiers in Oman and the GCC:

• The TeSys Giga LC1G is rated for high-power AC motor switching beyond standard TeSys Deca contactor limits.
• Robust contact and arc-extinguishing design withstands frequent high-current motor starting duty cycles.
• Front and rear power terminal options adapt to different motor control center bus layouts.
• A range of AC and DC coil voltages matches varied motor control center control philosophies.
• Electronic coil control options reduce control circuit inrush when switching multiple large contactors.
• Auxiliary contact and mechanical latching accessories support interlocking and reversing configurations.
• Direct mounting compatibility with TeSys Giga overload relays simplifies complete starter assembly.
• Molded housing construction is sized appropriately for high current ratings without oversized panel space.

Industrial Applications

The Schneider Electric TeSys Giga LC1G High-Power Contactor is specified in motor control centers for large pumps, compressors, and conveyor drives across Oman’s oil and gas, cement, and desalination sectors, wherever motor ratings exceed what standard TeSys Deca contactors can safely switch. Panel builders in Sohar’s industrial zone rely on the TeSys Giga range for heavy-duty starter assemblies feeding critical process motors.
