3. Продукт бүтүп калдыview

The Schneider Electric MJL36800 is an 800-Amp, 600-Volt molded case circuit breaker. It features a robust design for reliable circuit protection. The main operating handle indicates the breaker's status (ON/OFF/TRIPPED).

4. Орнотуу жана орнотуу

Installation of the MJL36800 circuit breaker requires adherence to all national and local electrical codes. Ensure the mounting surface is stable and capable of supporting the breaker's weight (approximately 111 pounds).

4.1 Монтаждоо

Securely mount the circuit breaker in its intended enclosure or panel using appropriate hardware. Refer to the specific enclosure instructions for proper mounting orientation and clearances.

4.2 Зымдарды туташтыруу

Connect the electrical conductors to the breaker terminals. The MJL36800 is designed for use with Copper (Cu) or Aluminum (Al) conductors. Refer to the specifications for appropriate wire sizes and torque values.

• Дирижер диапазону: #3/0 AWG to 500 kcmil (95-240 mm²)
• Терминалдык момент: 450 lb-in (50 N-m)

Ensure all connections are clean, tight, and free from insulation interference. Double-check all wiring against the system's electrical schematics.

5. Иштөө нускамалары

The circuit breaker's handle indicates its operational status.

• ON позициясы: The handle is fully up, indicating the circuit is closed and power is flowing.
• ӨЧҮРҮҮ абалы: The handle is fully down, indicating the circuit is open and power is interrupted.
• БУРУЛУП КАЛГАН абал: The handle is in an intermediate position (between ON and OFF), indicating an overcurrent condition has occurred and the breaker has automatically opened the circuit.

5.1 КҮЙГҮЗҮҮ/ӨЧҮРҮҮ

1. To turn the breaker OFF, push the handle firmly down to the 'OFF' position.
2. To turn the breaker ON, push the handle firmly up to the 'ON' position.

5.2 Ачууланган өчүргүчтү баштапкы абалга келтирүү

If the breaker trips, it indicates an electrical fault. Before resetting, investigate and resolve the cause of the trip.

1. Move the handle fully to the 'OFF' position. This resets the internal tripping mechanism.
2. Push the handle firmly up to the 'ON' position.
3. If the breaker immediately trips again, do not attempt to reset it further. Contact qualified electrical personnel to diagnose and repair the fault.

6. Техникалык тейлөө

Regular maintenance helps ensure the longevity and reliable operation of the circuit breaker. All maintenance should be performed by qualified personnel.

• Визуалдык текшерүү: Periodically inspect the breaker for any signs of physical damage, discoloration, loose connections, or excessive dust accumulation.
• Тазалоо: Keep the breaker and its surroundings clean and free of dust and debris. Use a dry, lint-free cloth for cleaning. Do not use solvents or abrasive cleaners.
• Туташуу текшерүүлөрү: Periodically verify that all electrical connections are tight and torqued to the specified values.

7. Кыйынчылыктарды

This section addresses common issues that may arise with the circuit breaker.

• Көп кездешүүчү кырсыктар: This indicates a persistent overcurrent or short-circuit condition in the protected circuit. Do not repeatedly reset the breaker without investigating the cause. Possible causes include overloaded circuits, faulty equipment, or wiring issues.
• Сыноочу баштапкы абалга келтирилбейт: If the breaker handle does not stay in the 'ON' position after being moved to 'OFF' and then 'ON', there may still be a fault present, or the breaker itself could be damaged. Do not force the handle.
• Ашыкча ысып кетүү: Signs of overheating (discoloration, melting, burning smell) around the breaker or its terminals indicate a serious problem, possibly loose connections or an overloaded circuit. Immediately de-energize the circuit and have it inspected by qualified personnel.
