5. Important Discontinuation Notice

LC1F500 series including LC1F500M7 / LC1F500Q7 are fully discontinued.

Stock spare parts are gradually depleted. Для новых проектов, select the replacement directly:

✅ LC1G500KUEN (Wide voltage coil 100–250 V AC/DC)

✅ LC1G500LSEA (200–500 V AC/DC)

LC1G500 shares the same current rating, but dimension differs; cabinet layout needs hole dimension verification.

6. Типичные применения

3-phase fans, водяные насосы, воздушные компрессоры, дробилки, variable frequency drive mains bypass and other LV motor circuits up to 250 кВт.

1) Complete dimension drawing of LC1F500;

2) Comparison checklist for LC1F500 ↔ LC1G500 replacement;

3) Full coil voltage model list.

Шнайдер LC1F500 (TeSys F Series)

✅ Mechanical durability: 10 миллион циклов (10×10⁶ циклов)

Условия испытания: Rated control voltage, работа без нагрузки.

Supplementary reference parameters:

1. Электрическая долговечность (АС-3, 400 В, 500 А): Приблизительно. 150,000 циклы;

3. Reminder: Данная модель снята с производства; replacement model LC1G500.

Official Replacement Models for Schneider LC1F500 (ТеСис Ф)

LC1F500 full series discontinued. Official upgrade series: TeSys Giga LC1G500 (3-столб). It offers identical electrical rating: 500 A under AC-3 at 440 В.

1. Primary Direct Replacement Models (Sorted by Coil Voltage)

Model description:

KUEN: Стандартная версия, 100~250 V (Top choice to replace M7)

LSEA: Расширенная версия, 200~500 V (To replace Q7)

EHEA: Расширенная версия, 48~130 V (To replace F7)

2. Critical Notes During Replacement
3. Mounting dimensions are not interchangeable

LC1G width is roughly 35% narrower than LC1F;

✅ To reuse existing mounting holes: Install adaptation base LA9GRFB2 (Suitable for LC1G265～500), no new drilling required.

2. Accessories are incompatible; old LC1F accessories cannot be reused

Оригинал: LA1F auxiliary contacts, LA7F mechanical interlock cannot be mounted on LC1G

New accessories for LC1G:

Вспомогательные контакты: LA9G series

Механическая блокировка: LA9G970 (Horizontal forward/reversing)

3. Matching thermal overload relay updated

Original matched LR9F7375; LC1G500 matches LR9G series electronic thermal relays.

4. Сравнение производительности

Механическая прочность: LC1F500 = 10 миллион циклов; LC1G500 = 8 миллион циклов

AC-3 rated current: Идентичный 500 A @440 V

LC1G Advantages: Electronic wide-voltage coil, stronger voltage fluctuation resistance, contact wear diagnosis available.

3. Alternative Solutions for Two Scenarios
4. Emergency spare parts solution

For urgent on-site maintenance: Purchase original stocked LC1F500 from market (Price increased, supply tight, watch out for refurbished units). Not allowed for new projects.

2. Cross-brand alternative (Non-Schneider OEM)

Siemens 3RT1075, ABB AF580; Only applicable for retrofit projects, not recommended for new cabinet design.

Simplified Selection Advice

For most domestic working conditions (Original coil AC220V LC1F500M7)

👉 Preferred option: LC1G500KUEN + LA9GRFB2 adaptation base (If original mounting holes need reservation)

Service Life Parameters of Schneider LC1G500 (ТеСис Гига)

1. Механическая долговечность (Official Rating)

8 миллион циклов (8×10⁶ циклов)

Tested under no-load condition with rated control voltage.

Compare with old LC1F500: Механическая прочность 10 миллион циклов, slightly lower.

2. Electrical Durability (АС-3, 400 В, 500 A Motor Load)

✅ Official standard reference value: 150,000 циклы (Same as LC1F500 datasheet value)

Important Remarks:

1. Electrical durability is not a fixed value, affected by operating frequency, starting current, температура окружающей среды, surge suppression and start-stop frequency;
2. Under AC-3e (Heavy-duty frequent start-stop), electrical durability will be significantly lower than 150,000 циклы;
3. Under AC-4 (Inching, reverse braking), electrical durability is only 20,000～30,000 cycles;
4. Under AC-1 resistive load (Heaters), electrical durability can reach more than 500,000 циклы.
5. Extra Key Advantages (LC1G VS LC1F)

LC1G500 supports independent replacement of main contact assembly!

When contacts are burned out, only the contact module needs replacement instead of the whole contactor, greatly reducing long-term maintenance cost; LC1F500 does not support separate contact replacement. Once contacts are damaged, the whole unit must be replaced.

4. Maximum Allowable Operating Frequency

АС-3: 600 циклов/час

AC-3e: 600 циклов/час

АС-1: 300 циклов/час

АС-4: 150 циклов/час
