5. Instalasi jeung Wiring
Proper installation is crucial for the safe and effective operation of the MARSTEK Smart Circuit Breaker. Refer to the wiring diagram below and follow all safety precautions.

Léngkah-léngkah pamasangan:
- Pegatkeun daya: Before starting any electrical work, ensure all power to the circuit is completely disconnected at the main service panel. Verify with a voltage panguji.
- Pamasangan: Mount the circuit breaker securely in a suitable electrical enclosure or panel. The device is designed for DIN rail mounting or screw mounting.
- Wiring Input: Connect the incoming Neutral (N) wire to the terminal marked 'N IN' and the incoming Live (L) wire to the terminal marked 'L IN'.
- Wiring kaluaran: Connect the outgoing Neutral (N) wire from the terminal marked 'N OUT' and the outgoing Live (L) wire from the terminal marked 'L OUT' to the load you wish to protect.
- Sambungan Aman: Ensure all terminal screws are tightened securely to prevent loose connections, which can cause overheating or intermittent operation.
- Pamulihan kakuatan: Once all connections are verified and secure, restore power to the circuit at the main service panel.
6. Operation and Parameter Settings
Upon power-up, the device will display real-time voltage and current. You can adjust the protection parameters to suit your specific needs.
Adjusting Protection Parameters:
- Lebetkeun Setélan: Pencét panjang SET button until the display changes, indicating entry into the settings menu.
- Navigasi Parameter: Ngagunakeun éta Up (▲) jeung Turun (▼) buttons to cycle through the available parameters (e.g., overvoltage trip value, undervoltage trip value, overcurrent trip value, recovery delay time).
- Pilih Parameter: Pencét éta SET button briefly to select the currently displayed parameter for adjustment.
- Saluyukeun Nilai: Ngagunakeun éta Up (▲) jeung Turun (▼) buttons to change the parameter's value.
- Konfirmasi sareng Kaluar: Pencét SET again to confirm the new value and move to the next parameter. To exit the settings menu at any time, long press the SET kancing.
Default Protection Settings:
- Overvoltage lalampahan: 140V
- Undervoltage lalampahan: 90V
- Overcurrent Trip: 63A
- Automatic Recovery Delay: 30 seconds
Fungsi Reset Otomatis:
Upami aya overvoltatage, undervoltage, or overcurrent condition, the circuit breaker will automatically cut off power to protect the connected load. After a default delay of 30 seconds, the device will attempt to restore power. If the fault condition persists, it will remain disconnected and attempt to reset again after another delay.
