4. Acessórios compatíveis

Relé de sobrecarga térmica

Matching electronic thermal relay: LR9F7375 (132～220 A)

Observação: Direct mounting between LC1F500 and LR9F7375 requires swapping Phase A and Phase C terminals of the thermal relay for alignment.

Contatos Auxiliares

LA1F, LA8F auxiliary contact modules (Sem contatos auxiliares integrados; need to be ordered separately).

Intertravamento Mecânico

LA7F406 (For forward/reversing circuit).

5. Important Discontinuation Notice

LC1F500 series including LC1F500M7 / LC1F500Q7 are fully discontinued.

Stock spare parts are gradually depleted. Para novos projetos, 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. Aplicações Típicas

3-phase fans, bombas de água, compressores de ar, trituradores, variable frequency drive mains bypass and other LV motor circuits up to 250 kW.

Schneider LC1F500 (TeSys F Series)

✅ Mechanical durability: 10 milhões de ciclos (10×10⁶ ciclos)

Condição de teste: Tensão nominal de controle, operação sem carga.

Supplementary reference parameters:

1. Durabilidade elétrica (AC-3, 400 V, 500 UM): Aprox.. 150,000 ciclos;
2. Frequência máxima de operação: 2400 ciclos/hora;
3. Lembretes: Este modelo foi descontinuado; replacement model LC1G500.

Official Replacement Models for Schneider LC1F500 (TeSys F)

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

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

Model description:

KUEN: Versão padrão, 100~250 V (Top choice to replace M7)

LSEA: Versão avançada, 200~500 V (To replace Q7)

EHEA: Versão avançada, 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

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

New accessories for LC1G:

Contatos auxiliares: LA9G series

Intertravamento mecânico: LA9G970 (Horizontal forward/reversing)

3. Matching thermal overload relay updated

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

4. Comparação de desempenho

Durabilidade mecânica: LC1F500 = 10 milhões de ciclos; LC1G500 = 8 milhões de ciclos

AC-3 rated current: Idêntico 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 (TeSys Giga)

1. Durabilidade Mecânica (Official Rating)

8 milhões de ciclos (8×10⁶ ciclos)

Tested under no-load condition with rated control voltage.

Compare with old LC1F500: Durabilidade mecânica 10 milhões de ciclos, um pouco mais baixo.

2. Durabilidade Elétrica (AC-3, 400 V, 500 A Motor Load)

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

Important Remarks:

1. Electrical durability is not a fixed value, affected by operating frequency, corrente inicial, temperatura ambiente, surge suppression and start-stop frequency;
2. Under AC-3e (Heavy-duty frequent start-stop), electrical durability will be significantly lower than 150,000 ciclos;
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 ciclos.
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

AC-3: 600 ciclos/hora

AC-3e: 600 ciclos/hora

AC-1: 300 ciclos/hora

AC-4: 150 ciclos/hora
