جهات الاتصال المساعدة

LA1F, LA8F auxiliary contact modules (No built-in auxiliary contacts; need to be ordered separately).

التعشيق الميكانيكي

LA7F406 (For forward/reversing circuit).

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. التطبيقات النموذجية

3-phase fans, مضخات المياه, ضواغط الهواء, الكسارات, variable frequency drive mains bypass and other LV motor circuits up to 250 كيلوواط.

Official Replacement Models for Schneider LC1F500 (TeSys F)

LC1F500 full series discontinued. Official upgrade series: TeSys Giga LC1G500 (3-القطب). 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: الإصدار القياسي, 100~250 V (Top choice to replace M7)

LSEA: Advanced version, 200~500 V (To replace Q7)

EHEA: Advanced version, 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

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

New accessories for LC1G:

اتصالات مساعدة: LA9G series

التعشيق الميكانيكي: LA9G970 (Horizontal forward/reversing)

3. Matching thermal overload relay updated

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

4. Performance Comparison

المتانة الميكانيكية: LC1F500 = 10 مليون دورة; LC1G500 = 8 مليون دورة

AC-3 rated current: تطابق 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 (تيسيس جيجا)

1. Mechanical Durability (Official Rating)

8 مليون دورة (8×10⁶ cycles)

Tested under no-load condition with rated control voltage.

Compare with old LC1F500: المتانة الميكانيكية 10 مليون دورة, slightly lower.

2. المتانة الكهربائية (ايه سي-3, 400 V, 500 A Motor Load)

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

ملاحظات هامة:

1. Electrical durability is not a fixed value, affected by operating frequency, البدء الحالي, درجة الحرارة المحيطة, surge suppression and start-stop frequency;
2. Under AC-3e (Heavy-duty frequent start-stop), electrical durability will be significantly lower than 150,000 دورات;
3. Under AC-4 (Inching, reverse braking), electrical durability is only 20,000～30,000 cycles;
4. Under AC-1 resistive load (سخانات), electrical durability can reach more than 500,000 دورات.
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

ايه سي-3: 600 دورات / ساعة

AC-3e: 600 دورات / ساعة

ايه سي-1: 300 دورات / ساعة

AC-4: 150 دورات / ساعة
