3. Особенности продукта
- IP65 Circuit Breaker DIN Rail Box: Constructed from durable PC+ABS material, offering high impact resistance, high heat resistance, and excellent dimensional stability. It is V1 grade flame retardant, resistant to acid, alkali, solvents, and UV radiation. The transparent cover allows for easy visual inspection of the circuit breaker status. This 3-way box provides ample space for convenient wiring and installation.
- Миниатюрный автоматический выключатель: Features a built-in arc squelching magnet for high arc extinction, a flame-retardant enclosure, silver contacts, and pure copper coils to ensure high quality and reliable performance.
- Множественная защита: Provides isolation, short circuit protection (for 48-400V DC or 90-400V AC systems), and overload protection with a C-curve trip characteristic and thermal magnetic trip mechanism. It is suitable for systems ranging from 12V-400V DC or 90-400V AC.
- Non-Polarized Design: The circuit breaker does not require polarity distinction, allowing for connection in either direction. This simplifies installation and reduces wiring errors, making it ideal for applications where polarity may reverse, such as reversible motors, battery charge/discharge switching, bidirectional current protection (EV charging/discharging circuits, solar power systems), and industrial reversible drive systems.
- Wide Cable Range: Includes two types of IP68 cable glands. One-hole glands are suitable for 2-conductor wires ranging from 9-16mm (0.35-0.63 inches). Two-hole glands are suitable for wires ranging from 4-6mm (0.15-0.23 inches).

6. Настройка и установка
Follow these steps for proper installation of your circuit breaker box:
- Подготовьте монтажную поверхность: Choose a suitable location for mounting. For outdoor installations, vertical mounting is crucial to prevent water ingress through panel gaps.
- Просверлите монтажные отверстия: Open the lid of the waterproof box. Use the box as a template to mark the screw hole positions on the wall. Drill holes with an appropriate drill bit and insert expansion tubes if necessary.
- Установите коробку: Fix the box to the wall using the provided screws.
- Install Cable Glands: Insert the waterproof cable glands into the designated holes on the box. Screw the lock nut tightly from the inside.
- Проводные соединения:
- Strip the insulation from your cables to the appropriate length.
- Insert the cable through the gland and connect it to the circuit breaker terminals. Use the provided crimp ferrules to ensure tight and secure connections.
- If the cable is too thin for the gland, use the provided insulating tape to seal the cable with the gland for a waterproof seal.
- Refer to the wiring diagrams below for AC and DC system connections.
- Закрепите крышку: After wiring, cover the circuit breaker box with its lid and fix it with the remaining screws. Insert the rubber plugs into the screw holes on the box cover to prevent rust and enhance waterproofing.

7. Инструкция по эксплуатации
The DIHOOL AC DC Circuit Breaker operates as a standard miniature circuit breaker. The toggle switch on the breaker indicates its status:
- НА: Power is flowing through the circuit.
- OFF: Power to the circuit is interrupted.
- TRIPPED: The breaker has automatically switched to the OFF position due to an overload or short circuit.
To restore power after a trip, first identify and resolve the cause of the trip. Then, firmly push the toggle switch to the OFF position before pushing it back to the ON position.
Due to its non-polarized nature, the input and output connections are reversible. This means the left/right polarity sequence and the cable in/out direction can be reversed without affecting functionality, simplifying installation in various setups.

8. Техническое обслуживание
Regular maintenance helps ensure the longevity and reliable operation of your circuit breaker:
- Визуальный осмотр: Periodically inspect the circuit breaker box for any signs of physical damage, cracks, or discoloration. Check the transparent lid for clarity.
- Проверка связи: Ensure all wire connections remain tight and secure. Loose connections can lead to overheating and potential hazards.
- Чистота: Keep the exterior of the box clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Целостность уплотнения: Verify that the cable glands and rubber plugs for the screw holes are properly seated and sealed to maintain the IP65 waterproof rating.
9. Поиск Неисправностей
If you encounter issues with your circuit breaker, consider the following common troubleshooting steps:
- Частое срабатывание выключателя:
- Перегрузка: The connected load may be drawing too much current. Reduce the load or ensure the circuit capacity matches the demand.
- Короткое замыкание: A direct connection between live and neutral/ground wires. Inspect wiring for damage, loose connections, or faulty appliances.
- Неисправный прибор: Disconnect appliances one by one to identify a malfunctioning device.
- Отсутствует питание в цепи:
- Breaker in OFF position: Check if the breaker is simply switched off.
- Ослабленные соединения: Inspect all wiring connections within the box and at the load for tightness.
- Проблема с электропитанием на вышестоящем узле: Check the main power supply or any upstream breakers/fuses.
- Вода внутри коробки:
- Improper Gland Installation: Ensure cable glands are tightened correctly around the cables.
- Missing Rubber Plugs: Verify all screw holes on the lid have their rubber plugs inserted.
- Horizontal Mounting (Outdoor): If mounted horizontally outdoors, water can ingress. Re-mount vertically.
- Damaged Enclosure: Inspect the box for cracks or damage that could compromise the seal.
Если проблема не исчезнет после проведения этих проверок, обратитесь к квалифицированному электрику.
