1. Introduction

This manual provides essential information for the safe installation, operation, and maintenance of the JFUDJKLI EADZ47L-63SVP Residual Current Circuit Breaker with Overload and Overvoltage Protection (SPD). This device is designed to protect electrical circuits from overcurrents (overload or short circuit), earth leakage faults, and transient overvoltages, ensuring enhanced electrical safety in residential and commercial applications. Please read this manual thoroughly before installation and keep it for future reference.

2. Safety Information

WARNING: Electrical installation and maintenance should only be performed by qualified and licensed electricians in accordance with all local and national electrical codes and regulations. Failure to comply with these instructions may result in electric shock, fire, serious injury, or death.

• Always disconnect power at the main service panel before working on electrical circuits.
• Ensure the device rating matches the circuit requirements.
• Do not operate the device if it appears damaged.
• Never bypass or tamper with the safety features of this device.
• Proper grounding is essential for effective protection.

3. Product Overview

The EADZ47L-63SVP is a compact device integrating multiple protection functions. It combines a Residual Current Circuit Breaker (RCCB) for earth leakage protection, a Miniature Circuit Breaker (MCB) for overload and short-circuit protection, and a Surge Protective Device (SPD) for overvoltage protection. The device features a test button for verifying the earth leakage protection function.

Figure 1: JFUDJKLI EADZ47L-63SVP Circuit Breaker with key features and dimensions. The image displays the front view of the circuit breaker, showing the ON/OFF switch, test button, and indicators for voltage, lightning, and leakage protection. Dimensions are indicated as 71mm width, 94mm depth, and 62mm height, with a 45mm width for the SPD module. Key specifications like rated voltage, current, poles, segmentation capacity, residual operating current, action time, and tripping characteristics are also listed.

Key Components:

• Main Switch (ON/OFF): Controls the power flow through the circuit.
• Test Button (Yellow): Used to manually test the Residual Current Device (RCD) function.
• Voltage Protection Indicator: Shows the status of overvoltage protection (AC275V±5V, AC175V±5V).
• Lightning Protection Indicator: Shows the status of surge protection.
• Leakage Protection Indicator: Shows the status of earth leakage protection.
• Reset Button (R): Used to reset the leakage protection after a trip.

5. Setup and Installation

Installation must be carried out by a qualified electrician. Ensure all power is disconnected before beginning installation.

1. Power Disconnection: Turn off the main power supply at the consumer unit/distribution board. Verify with a voltage tester that no power is present.
2. Mounting: Mount the EADZ47L-63SVP onto a DIN rail within an appropriate enclosure. Ensure it is securely fastened.
3. Wiring:
   • Connect the incoming live (L) and neutral (N) wires to the top terminals of the device.
   • Connect the outgoing live (L) and neutral (N) wires to the bottom terminals, leading to the protected circuit.
   • Ensure the protective earth (PE) conductor is properly connected to the earth bar in the distribution board. The device itself is 2P+PE, indicating it provides protection for two poles (Live and Neutral) and has an integrated earth connection for the SPD.
   • Tighten all terminal screws to the manufacturer's specified torque to prevent loose connections and overheating.
4. Verification: Double-check all connections for correctness and security.
5. Power Restoration: Restore power to the main service panel.

6. Operating Instructions

Switching ON/OFF:

• To turn the circuit ON, push the main switch lever upwards to the "ON" position.
• To turn the circuit OFF, push the main switch lever downwards to the "OFF" position.

Testing the RCD Function:

It is recommended to test the RCD function regularly (e.g., monthly) to ensure proper operation.

1. Ensure the circuit breaker is in the "ON" position and power is flowing through the circuit.
2. Press the yellow "Test" button. The device should immediately trip to the "OFF" position, indicating the RCD function is working.
3. To restore power, push the main switch lever fully downwards to reset, then push it upwards to the "ON" position.
4. If the device does not trip when the test button is pressed, or if it fails to reset, consult a qualified electrician immediately. Do not use the protected circuit until the issue is resolved.

Overload/Short Circuit Protection:

In case of an overload or short circuit, the device will automatically trip to the "OFF" position. Identify and rectify the cause of the fault (e.g., unplug faulty appliances, reduce load) before attempting to reset the breaker. To reset, push the main switch lever fully downwards, then upwards to "ON".

Leakage Protection:

If an earth leakage fault occurs, the device will trip. The "Leakage Protection" indicator may provide visual feedback. To reset, press the "R" (Reset) button, then push the main switch lever fully downwards, then upwards to "ON". If the device trips repeatedly, there is a persistent leakage fault that needs to be investigated by a qualified electrician.

Overvoltage Protection (SPD):

The integrated Surge Protective Device (SPD) protects against transient overvoltages. The "Lightning Protection" and "Voltage Protection" indicators provide status. If these indicators show a fault (e.g., turn red or disappear, depending on the specific indicator design), the SPD module may need replacement. Consult a qualified electrician.

7. Maintenance

• Regular Testing: Perform the RCD test monthly as described in the "Operating Instructions" section.
• Visual Inspection: Periodically inspect the device for any signs of physical damage, discoloration, or loose connections. Ensure the indicators are functioning correctly.
• Cleaning: Keep the device and its enclosure clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
• Professional Check: It is advisable to have a qualified electrician inspect your electrical system, including circuit breakers, periodically (e.g., every 3-5 years).
