LC1F115M7 — Schneider Electric TeSys F Heavy Duty Contactor
The Schneider Electric TeSys F is a heavy-duty contactor covering 115 A to 800 A for large motor and load switching applications on three-phase supply up to 690 V AC, designed for demanding duty cycles in industrial motor control centres, large DOL and Y/D starters, and capacitor bank switching where the smaller TeSys D family reaches its ratings limit. The LC1F series delivers AC-3 motor switching with electrical endurance matching the TeSys D family on a per-duty-cycle basis, using silver alloy main contacts engineered for the higher current densities of large motor switching and incorporating arc chutes designed to extinguish the large arcs produced when interrupting high-current inductive loads at full voltage.
The TeSys F contactor coil is available in the same wide voltage range as TeSys D — 24 V to 480 V AC and 24 V to 250 V DC — ensuring compatibility with existing motor control panel control circuit voltage standards. The front-mounted auxiliary contact blocks and side-mounted auxiliary contact banks from the TeSys F accessory catalogue are field-fitted without tools, and mechanical interlock bridges are available for reversing contactor pairs covering the full current range. The LC1F contactor can be combined with LUF soft-start modules for AC-3 switching of motors up to 400 kW in line-start applications where a softstarter is not justified but direct switching would cause unacceptable supply disturbance.
In Saudi Arabia, the TeSys F KSA serves the large motor switching market at industrial motor control centres operating motors from approximately 55 kW to 400 kW. SABIC's Jubail petrochemical complexes and ARAMCO's large motor MCC assemblies routinely specify TeSys F for main contactors on large pump, fan, and compressor motor starters. Port authorities at King Fahd Industrial Port Jubail and King Abdulaziz Port Dammam use TeSys F in crane motor control panels. Power factor correction panel manufacturers use TeSys F for large capacitor bank switching with suppression modules.
Razz Middle East stocks TeSys F contactors from 115 A to 400 A in common coil voltages for same-week delivery to MCC panel builders and industrial maintenance teams across Saudi Arabia.

Key Features & Benefits
- Silver alloy main contacts with dedicated arc chutes handle the high current densities of large motor switching, delivering reliable contact performance at full rated current across the 115–800 A range.
- Wide coil voltage range matching TeSys D family (24 V to 480 V AC, 24 V to 250 V DC) ensures compatibility with existing motor control centre control circuit wiring without coil voltage modification.
- Field-fit auxiliary contact blocks and mechanical interlock bridges for reversing pairs are installed without tools, matching the TeSys D accessory system and simplifying MCC panel assembly and modification.
- AC-4 utilisation category rating for plug reversal and jogging at full current covers demanding hoist, crane traversal, and reversing conveyor applications without contact derating.
- Compatible with LUF soft-start modules for reduced-voltage switching of large motors in line-start applications, eliminating supply voltage disturbance without a dedicated softstarter panel.
- Capacitor switching variant (LC1F-C) with resistors and suppression circuitry handles the high inrush and transient voltages of capacitor bank energisation in power factor correction systems.
- Robust mechanical construction rated for continuous duty at 50°C ambient covers Saudi Arabia's industrial plant room conditions without thermal derating of the contactor's rated current.
Industrial Applications in Saudi Arabia
- Large pump motor DOL and Y/D starter main contactors in SABIC petrochemical plant motor control centres at Jubail, where 115–400 A ratings cover the 55–200 kW motor range typical of process pump MCCs.
- Large fan motor starting panels at cement and steel plants in Riyadh, Dammam, and Jubail, where TeSys F provides reliable switching of induced draft and forced draft fan motors up to 800 kW.
- Crane motor control panels at King Fahd Industrial Port Jubail and King Abdulaziz Port Dammam, where AC-4 duty cycle rating handles the frequent reversing and plugging of portal crane travel motors.
- Large HVAC chiller motor starter panels in district cooling plants across Riyadh, Jeddah, and Makkah, where direct-on-line starting of 160–400 kW chiller compressor motors requires TeSys F current ratings.
- Power factor correction capacitor bank switching panels at industrial facilities in Jubail and Yanbu industrial cities, where LC1F-C capacitor switching contactors handle the high inrush current of large capacitor banks.
- Water treatment pump station MCC panels for large submersible and vertical turbine pump motors at NWC infrastructure projects, where Y/D reduced-voltage starting requires TeSys F for both main and star contactors.
- Oil and gas production facility motor control centres for large injection pump and process compressor motor starters, where ARAMCO material specification requires IEC 60947-4-1 certified contactors with proven endurance data.
