1. Úvod
This manual provides instructions for the Renogy Suntree 32 Amp Single-Pole DC Circuit Breaker. This device is designed to protect DC electrical installations against overloads and short circuits. It incorporates both thermal and magnetic tripping mechanisms to ensure reliability and safety. The circuit breaker automatically disconnects the electrical circuit upon fault detection, preventing wire damage and fire hazards. It can also be manually operated for system maintenance. Its reversible connection design allows for wiring in either direction, supporting bidirectional current flow. A built-in indicator window provides immediate visual confirmation of the circuit breaker's contact position. The buckle design facilitates easy installation on standard DIN rails.

5. Instalace
5.1 Montáž na DIN lištu
- Ensure the DIN rail is securely mounted within the breaker box or enclosure.
- Align the circuit breaker's top slot with the top edge of the DIN rail.
- Press the circuit breaker firmly against the DIN rail until the buckle mechanism clicks into place, securing it.
- Verify the circuit breaker is firmly attached and does not wobble.

5.2 Zapojení kabeláže
The Renogy Suntree DC Circuit Breaker is designed for reversible connection, meaning it can be wired in either direction. However, it is crucial to maintain correct polarity for DC systems.
- Identify the positive (+) and negative (-) terminals on the circuit breaker and your DC system components.
- Connect the positive wire from the power source (e.g., solar panel, battery) to one terminal of the circuit breaker.
- Connect the positive wire to the load (e.g., inverter, charge controller) from the other terminal of the circuit breaker.
- Ensure all wire connections are tight and secure to prevent loose contacts and potential arcing.
- Double-check all wiring for correct polarity before applying power.

6. Provoz
6.1 Zapnutí/vypnutí
- To switch the circuit breaker ON, push the toggle switch upwards until it locks into the "ON" position. The indicator window will show green.
- To switch the circuit breaker VYPNUTO, pull the toggle switch downwards until it locks into the "OFF" position. The indicator window will show red.
6.2 Automatic Tripping
In the event of an overload or short circuit, the circuit breaker will automatically trip to the "OFF" position, interrupting the circuit and protecting connected equipment. The indicator window will show red.
6.3 Resetting the Circuit Breaker
After an automatic trip, identify and resolve the cause of the fault (e.g., remove overload, fix short circuit) before attempting to reset the breaker. Once the fault is cleared, push the toggle switch downwards to fully reset it, then push it upwards to the "ON" position.

7. Údržba
The Renogy Suntree DC Circuit Breaker requires minimal maintenance. Regular inspections are recommended to ensure optimal performance and safety.
- Pravidelná vizuální kontrola: Regularly check the circuit breaker for any signs of physical damage, discoloration, or loose connections.
- Čištění: If necessary, gently clean the exterior of the circuit breaker with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Test funkčnosti: Periodically test the manual switching mechanism by turning the breaker OFF and ON.
- Kontrola připojení: Ensure all terminal connections remain tight. Loose connections can lead to overheating and potential hazards.
Note: Do not attempt to open or repair the circuit breaker. Refer to qualified personnel for any issues beyond basic inspection and cleaning.
8. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| Jistič se často vypíná. | Přetížení obvodu, zkrat nebo vadný spotřebič. | Reduce the load on the circuit. Inspect wiring and connected devices for short circuits. Disconnect faulty appliances. |
| Jistič se neresetuje. | Trvalá závada (přetížení/zkrat) nebo vnitřní poškození jističe. | Ensure the fault is completely cleared. If the fault is cleared and it still doesn't reset, the breaker may be damaged and require replacement. |
| Circuit breaker feels hot. | Overload, loose connections, or undersized wiring. | Check for overloads. Tighten all terminal connections. Verify wire gauge is appropriate for the current. |
| No power to the circuit, but breaker is ON. | Faulty wiring upstream/downstream, or internal breaker failure. | Check continuity of wiring. If wiring is intact, the breaker may be faulty and require replacement. |
