Schneider LAD6K10F Contactor Front Mechanical Latching Module

LAD6K10F = TeSys Deca front-mounted mechanical latching module (mechanical latch accessory) for contactors. Release coil voltage: 110…127 V AC/DC (110VAC specification as required)

Part Number Rule: LAD6K10 + voltage suffix

LAD6K10B: 24الخامس التيار المتناوب/تيار مستمر

LAD6K10F: 110~127V AC/DC (matches your 110VAC requirement)

LAD6K10M: 220~240V AC/DC

وظيفة: Clipped onto the front face of LC1D contactors to achieve pulse closing + mechanical holding.

1. Send a short pulse to the contactor main coil for closing.
2. The mechanical latch locks the contactor, and the main coil can be de-energized while the main circuit remains closed.
3. To open the circuit, send a short pulse to the E1/E2 release coil on LAD6K10; manual unlock is also available via the pushbutton.

غاية: For long-term closed circuits, continuous power supply to the contactor coil is eliminated, reducing power consumption and coil overheating.

فئة الحماية: IP2X

Operating ambient temperature: -25درجه مئوية ~ +55 درجه مئوية

الوزن الصافي: 0.07كجم

تصاعد: Tool-free snap-on front fit; terminals E1, E2 (release coil of latch module)

Operating Logic (شديد الأهمية)

1. إغلاق: Apply a short pulse to contactor main coil A1/A2 → contactor closes, LAD6K10 mechanical latch engages → main coil power can be cut off, main circuit stays ON.
2. افتتاح: Send a short pulse to E1/E2 (110VAC release coil) → mechanical latch trips → contactor opens. A manual reset button is provided for local unlocking.

⚠️ Do not energize the contactor main coil and the latch release coil simultaneously.

اختيار & معلومات الاستبدال

1. Larger-size counterpart: LA6DK20, compatible with LC1D80~D150 high-current contactors. LAD6K10 only covers up to LC1D80A.
2. البدائل المحلية: Mechanical latch attachments from Chint/Delixi with identical mounting dimensions and control logic; verify terminal definitions and coil power consumption before replacement.
3. Spare part note: LAD6K10F is sold separately as an accessory; contactor body is not included.

دليل استكشاف الأخطاء وإصلاحها

1. Contactor closes but cannot stay latched: Mechanical latch jamming, insufficient pulse duration, excessive wear on contactor stroke.
2. Electric release fails: Loose E1/E2 wiring, burnt coil, supply voltage outside 110~127V range; check that the pulse width is long enough.
3. احتراق الملف: Release coil kept energized longer than 10s (the most common root cause).

التطبيقات النموذجية

Fire-fighting pumps, المشجعين, bus tie breakers, and other power circuits requiring prolonged closed status, to cut continuous coil power and reduce heating.

Physical Dimensions of LAD6K10F (Mechanical Latching Module)

ارتفاع: 44 مم

عرض: 44 مم

6. Critical Usage Restrictions
7. LAD6K10F only supports up to LC1D80; LA6DK20 must be used for LC1D95 and larger models.
8. The E1/E2 release coil must only receive pulse signals (≥100ms). Continuous energization will burn out the coil.
9. Domestic models end with suffix C; imported models have no suffix C. They share identical dimensions and are fully interchangeable with LAD6K10F.
