5. Setup jeung Instalasi
Follow these steps for proper installation of the circuit breaker:
- Persiapan: Ensure all power to the installation area is disconnected and verified as off. Gather necessary tools (e.g., screwdrivers, wire strippers, multimeter).
- Pamasangan: Install the circuit breaker securely within a suitable distribution box or enclosure. The recommended installation method for 2-pole configurations is vertical mounting.
- Wiring: Connect the DC power lines to the circuit breaker terminals. The recommended wiring configuration is "Top in and Bottom out Wiring". Ensure all connections are tight and secure to prevent loose contacts and overheating.

- Verifikasi: After wiring, double-check all connections for correctness and tightness. Use a multimeter to verify proper voltage and continuity before restoring power.
6. Operasi
The circuit breaker features a simple ON/OFF toggle switch for operation.
- Pikeun ON: Push the toggle switch to the "ON" position (typically indicated by a green or upward position). This connects the circuit.
- Pikeun mareuman: Push the toggle switch to the "OFF" position (typically indicated by a red or downward position). This disconnects the circuit.
- Automatic Trip: In the event of an overload or short circuit, the breaker will automatically trip to the "OFF" position to protect the circuit. Before resetting, identify and resolve the cause of the trip.
- Ngareset: After an automatic trip, ensure the fault is cleared. Then, firmly push the toggle switch to the "OFF" position first, and then to the "ON" position to reset the breaker.

- Inspeksi périodik: Visually inspect the circuit breaker and its connections periodically for any signs of damage, discoloration, loose wires, or overheating.
- beberesih: Keep the circuit breaker free from dust and debris. Use a dry, non-conductive cloth for cleaning. Do not use liquids or abrasive cleaners.
- Uji coba: It is recommended to periodically test the trip mechanism by pressing the "PUSH TO TRIP" button (if present) or by simulating an overload condition under controlled circumstances, if qualified to do so.
- Kencangkeun sambungan: Periodically check and tighten all terminal connections to prevent resistance buildup and potential fire hazards.
