सुरक्षितता माहिती
- स्थापना आणि देखभाल केवळ पात्र इलेक्ट्रिशियनद्वारेच केली पाहिजे.
- Always disconnect power at the main supply before working on electrical circuits.
- Ensure proper grounding (for 2P-PE models) to maximize protection.
- जर उपकरण खराब झालेले दिसत असेल तर ते चालवू नका.
- Adhere to all local electrical codes and regulations.
सेटअप आणि स्थापना
The DZ47LED-63 circuit breaker is designed for DIN rail mounting within an electrical distribution board. Follow these general steps for installation:
- वीज खंडित होणे: Turn off the main power supply to the electrical panel where the circuit breaker will be installed. Verify with a voltage tester that no power is present.
- माउंटिंग: Clip the DZ47LED-63 onto the DIN rail securely.
- Wiring (2P Variant):
- Connect the live (L) input wire to the 'L' terminal and the neutral (N) input wire to the 'N' terminal on the top side of the breaker.
- Connect the live (L) output wire to the corresponding 'L' terminal and the neutral (N) output wire to the 'N' terminal on the bottom side of the breaker.
- This configuration provides Over-Voltage, Short Circuit, Leakage, and Overload Protection.

- Wiring (2P-PE Variant):
- Connect the live (L) input wire to the 'L' terminal, the neutral (N) input wire to the 'N' terminal, and the protective earth (PE) input wire to the 'PE' terminal on the top side of the breaker.
- Connect the live (L) output wire to the corresponding 'L' terminal, the neutral (N) output wire to the 'N' terminal, and the protective earth (PE) output wire to the 'PE' terminal on the bottom side of the breaker.
- This configuration provides Over-Voltage, Short Circuit, Leakage, Overload, and Ground Protection.

- Terminal Tightening: Ensure all terminal screws are tightened to the manufacturer's recommended torque to prevent loose connections and overheating.
- पॉवर रिस्टोरेशन: Once installation is complete and verified, restore power to the main supply.
ऑपरेटिंग सूचना
The DZ47LED-63 features a simple interface for operation and status indication:
- चालू/बंद स्विच: The main red lever controls the power flow. Push it up to the 'ON' position to supply power to the circuit. Push it down to the 'OFF' position to disconnect power.
- चाचणी बटण: The yellow 'TEST' button is used to manually test the leakage protection function. Pressing this button should trip the breaker, moving the main lever to the 'OFF' position. This simulates an earth leakage fault.
- रीसेट बटण: After the breaker trips (due to a fault or test), the 'RESET' button (labeled 'R') may need to be pressed before the main lever can be moved back to the 'ON' position.
- निर्देशक:
- Red 'Power' Indicator: Illuminates when power is supplied through the breaker.
- Green 'Ground' Indicator: Illuminates when the ground connection is properly established (for 2P-PE models).
नियमित चाचणी: It is recommended to press the 'TEST' button monthly to ensure the leakage protection mechanism is functioning correctly. If the breaker does not trip when the test button is pressed, it may be faulty and should be replaced by a qualified electrician.
देखभाल
The DZ47LED-63 is designed for minimal maintenance. However, periodic checks are advisable to ensure continued safe operation:
- व्हिज्युअल तपासणी: Regularly inspect the circuit breaker for any signs of physical damage, discoloration, or loose connections.
- स्वच्छता: Keep the area around the circuit breaker clean and free from dust and debris to ensure proper ventilation and operation.
- टर्मिनल घट्टपणा: Periodically check the tightness of the terminal screws. Loose connections can lead to overheating and potential hazards.
- व्यावसायिक तपासणी: It is recommended to have your electrical system, including circuit breakers, inspected by a qualified electrician every few years.
टीप: Do not attempt to open or repair the circuit breaker yourself. Refer all servicing to qualified personnel.
समस्यानिवारण
If your DZ47LED-63 circuit breaker trips or does not function as expected, consider the following:
- ब्रेकर ट्रिप वारंवार:
- ओव्हरलोड: The connected circuit may be drawing too much current. Disconnect some appliances or reduce the load.
- शॉर्ट सर्किट: A direct connection between live and neutral wires, or live and ground, can cause a trip. Inspect wiring and appliances for faults.
- पृथ्वी गळती: Current is flowing to ground through an unintended path. This could be due to faulty insulation, damaged appliances, or moisture. Disconnect appliances one by one to identify the faulty one.
- ओव्हर-व्हॉलtage: इनपुट व्हॉल्यूमtage may have exceeded the device's threshold (270V ± 5%). Check the incoming power supply.
- Lightning Surge: A lightning strike or surge in the electrical grid may have caused the lightning protection (SPD) to activate.
- ब्रेकर रीसेट होत नाही: If the breaker trips and cannot be reset (lever won't stay in 'ON' position), a persistent fault likely exists in the circuit. Do not force the lever. Investigate the cause of the trip before attempting to reset again.
- 'TEST' Button Does Not Trip Breaker: If pressing the 'TEST' button does not trip the breaker, the leakage protection mechanism may be faulty. The device should be replaced immediately by a qualified electrician.
- पॉवर इंडिकेटर नाही: If the red 'Power' indicator is off when the breaker is 'ON', check the incoming power supply to the breaker.
- No Ground Indicator (2P-PE models): If the green 'Ground' indicator is off, verify the protective earth connection.
If you are unable to identify or resolve the issue, contact a qualified electrician for assistance.
वापरकर्त्याच्या टीपा
- Label Circuits: Clearly label the circuits protected by each DZ47LED-63 breaker in your distribution board for easy identification during troubleshooting.
- Understand Trip Causes: Familiarize yourself with the common reasons for circuit breaker trips (overload, short circuit, earth leakage) to quickly diagnose minor issues.
- नियमित चाचणी ही महत्त्वाची आहे: Make the monthly 'TEST' button press a routine to ensure your leakage protection is always active.
- व्यावसायिक स्थापना विचारात घ्या: For optimal safety and compliance, especially with complex wiring or new installations, always opt for professional installation.
