5. Important Discontinuation Notice

LC1F500 series including LC1F500M7 / LC1F500Q7 are fully discontinued.

Stock spare parts are gradually depleted. 새로운 프로젝트의 경우, 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. 일반적인 응용 분야

3-phase fans, 물 펌프, 공기 압축기, 파쇄기, variable frequency drive mains bypass and other LV motor circuits up to 250 kW.

2. 최대 작동 주파수: 2400 주기/시간;
3. Reminder: 이 모델은 단종되었습니다; replacement model LC1G500.

Official Replacement Models for Schneider LC1F500 (테시스 F)

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

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

Model description:

KUEN: 표준 버전, 100~250 V (Top choice to replace M7)

LSEA: 고급 버전, 200~500 V (To replace Q7)

EHEA: 고급 버전, 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

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

New accessories for LC1G:

보조 접점: LA9G series

기계적 인터록: LA9G970 (Horizontal forward/reversing)

3. Matching thermal overload relay updated

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

4. 성능 비교

기계적 내구성: LC1F500 = 10 백만 사이클; LC1G500 = 8 백만 사이클

AC-3 rated current: 동일한 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 (테시스 기가)

1. 기계적 내구성 (Official Rating)

8 백만 사이클 (8×10⁶ 사이클)

Tested under no-load condition with rated control voltage.

Compare with old LC1F500: 기계적 내구성 10 백만 사이클, 약간 더 낮음.

2. Electrical Durability (AC-3, 400 다섯, 500 A Motor Load)

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

Important Remarks:

1. Electrical durability is not a fixed value, affected by operating frequency, 시동 전류, 주변 온도, surge suppression and start-stop frequency;
2. Under AC-3e (Heavy-duty frequent start-stop), electrical durability will be significantly lower than 150,000 사이클;
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 사이클.
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 주기/시간

AC-3e: 600 주기/시간

AC-1: 300 주기/시간

AC-4: 150 주기/시간
