5. Important Discontinuation Notice

LC1F500 series including LC1F500M7 / LC1F500Q7 are fully discontinued.

Stock spare parts are gradually depleted. For new projects, 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. 代表的な用途

3-phase fans, ウォーターポンプ, エアコンプレッサー, 破砕機, variable frequency drive mains bypass and other LV motor circuits up to 250 kW.

Official Replacement Models for Schneider LC1F500 (テシスF)

LC1F500 full series discontinued. Official upgrade series: TeSys Giga LC1G500 (3-ポール). 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: 標準バージョン, 100~250 V (Top choice to replace M7)

LSEA: 上級版, 200~500 V (To replace Q7)

EHEA: 上級版, 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

オリジナル: LA1F auxiliary contacts, LA7F mechanical interlock cannot be mounted on LC1G

New accessories for LC1G:

補助接点: LA9G series

機械的インターロック: LA9G970 (Horizontal forward/reversing)

3. Matching thermal overload relay updated

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

4. 性能比較

機械的耐久性: LC1F500 = 10 百万サイクル; LC1G500 = 8 百万サイクル

AC-3 rated current: 同一 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: LC1G500クエン + LA9GRFB2 adaptation base (If original mounting holes need reservation)

Service Life Parameters of Schneider LC1G500 (テシスギガ)

1. Mechanical Durability (Official Rating)

8 百万サイクル (8×10⁶ cycles)

Tested under no-load condition with rated control voltage.

Compare with old LC1F500: 機械的耐久性 10 百万サイクル, slightly lower.

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

✅ Official standard reference value: 150,000 サイクル (Same as LC1F500 datasheet value)

Important Remarks:

1. Electrical durability is not a fixed value, affected by operating frequency, 始動電流, 周囲温度, surge suppression and start-stop frequency;
2. Under AC-3e (Heavy-duty frequent start-stop), electrical durability will be significantly lower than 150,000 サイクル;
3. Under AC-4 (Inching, reverse braking), electrical durability is only 20,000～30,000 cycles;
4. Under AC-1 resistive load (ヒーター), electrical durability can reach more than 500,000 サイクル.
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 サイクル/時間

AC-3e: 600 サイクル/時間

AC-1: 300 サイクル/時間

AC-4: 150 サイクル/時間
