• ความไว: 30 mA (milliAmperes) for earth leakage protection.
• ความสามารถในการทำลาย: 10 kA (kiloAmperes), indicating its ability to safely interrupt high fault currents.
• เล่มที่tagอี คะแนน: 240/415V AC.
• ประเภทไฟฟ้ากระแสสลับ: Detects sinusoidal alternating residual currents.

4. การตั้งค่าและการติดตั้ง

Installation should only be carried out by a qualified electrician in accordance with national wiring regulations and standards.

4.1 การติดตั้ง

The Legrand DX3 RCBO is designed for DIN rail mounting. Ensure the DIN rail is securely fixed within an appropriate electrical enclosure.

1. Hook the top edge of the RCBO onto the DIN rail.
2. Press the bottom edge of the RCBO firmly until it clicks into place on the DIN rail.
3. Verify that the RCBO is securely mounted and does not wobble.

4.2 การเชื่อมต่อสายไฟ

Refer to the wiring diagram provided on the device and ensure all connections are tight and secure. Use appropriate cable sizes for the 25A current rating.

• Input Terminals (Top): Connect the incoming live and neutral conductors from the main supply.
• Output Terminals (Bottom): Connect the outgoing live and neutral conductors to the circuit being protected.
• Ensure correct polarity for live and neutral connections.
• Tighten terminal screws to the recommended torque to prevent loose connections and overheating.

Note: The schematic diagram on the device (visible in Figure 1) illustrates the internal wiring and connection points.

5. คู่มือการใช้งาน

5.1 การเปิด/ปิด

• To switch the RCBO ON, push the operating lever upwards to the 'I. On' position.
• To switch the RCBO ปิด, push the operating lever downwards to the 'O. Off' position.
• In case of a fault (overcurrent or earth leakage), the RCBO will automatically trip to the 'O. Off' position.

5.2 ปุ่มทดสอบ

The RCBO is equipped with a test button to verify its residual current protection function. This test button is labeled "Test frequently" on the device.

• With the RCBO in the 'I. On' position, press the 'T' (Test) button.
• The RCBO should immediately trip to the 'O. Off' position.
• If the RCBO does not trip, it indicates a malfunction, and the device must be replaced.
• To restore power after a test, reset the RCBO by pushing the lever fully down to 'O. Off' and then back up to 'I. On'.

6. การบำรุงรักษา

The Legrand DX3 RCBO requires minimal maintenance. Regular testing is the primary maintenance activity.

6.1 การทดสอบเป็นประจำ

It is recommended to test the RCBO using the test button at least once every three months to ensure its proper functioning. Follow the procedure described in Section 5.2.

6.2 การทำความสะอาด

If necessary, clean the exterior of the RCBO with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
