Schneider LC1F500P7 TeSys F Contactor 500A

The Schneider LC1F500P7 is a heavy-duty AC contactor from the TeSys F series. Rated at 500A, this three-pole contactor is designed for switching large motors, resistive loads, and power circuits in industrial applications. The coil operates at 230V AC, 50/60 Hz, providing reliable closing and holding characteristics. It is suitable for use in motor control centers, power distribution, and HVAC systems.

Electrical Ratings

Rated operational voltage Ue: 1000V AC (max). Conventional thermal current Ith: 500A (open or enclosed). AC-3 motor rating: 250 kW at 400V, 355 kW at 690V. AC-1 resistive load: 500A. Breaking capacity: 10 x In (5000A) at 690V. Mechanical durability: 5 million operations; electrical durability: 1 million operations under AC-3.

Coil Specifications

Coil voltage: 230V AC, 50/60 Hz. Inrush power: 550 VA (peak); holding power: 25 VA. Coil consumption is optimized for low heat dissipation. The contactor has an integrated suppression module socket (optional RC or varistor). Pick-up voltage: 0.85x Un; drop-out voltage: 0.3x Un. Response time: coil closing 30 ms, opening 25 ms.

Main Contacts and Auxiliaries

Three main contacts silver-tin oxide alloy, double-break design. They are rated for breaking capacity up to 690V. The LC1F500P7 comes with one NO and one NC auxiliary contact built-in (factory installed). Additional auxiliary contact blocks can be snapped on the front or side (up to 8 auxiliary contacts). Terminals are for busbar or cable connection, accepting up to 2 x 240 mm² copper or 185 mm² aluminum.

Mechanical and Environmental

Dimensions: 220 mm (H) x 162 mm (W) x 181 mm (D). Weight 6.5 kg. Mounting via screws or rail (with adapter). Operating temperature: -5°C to +55°C (no derating). Storage: -40°C to +80°C. The contactor is IP20 rated on terminals (finger-safe covers available).

Standards and Certifications

IEC 60947-4-1, UL 508, CSA C22.2. CE marked, CCC certified. The TeSys F series also complies with marine certifications (DNV, LR, ABS) for shipboard applications.

Applications

Used for motor starting of large compressors, pumps, crushers, mixers, and fans. Also as a main line contactor in industrial ovens, welding equipment, and capacitor banks. The 500A rating supports motors up to 250 kW at 400V.

Installation Notes

Ensure proper tightening torque: main terminals 35 Nm, auxiliary terminals 1.5 Nm. Use appropriate copper or aluminum lugs. For high-altitude installations above 2000m, derating applies per IEC standards.

Conclusion

The Schneider LC1F500P7 TeSys F contactor provides robust 500A switching with a 230V AC coil. Its high electrical durability and comprehensive certification make it a dependable choice for heavy-duty industrial applications.
