1. Introduction
The ETEK EKL13 RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is an advanced electrical safety device designed to protect against various electrical faults. It combines the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD), offering comprehensive protection against short circuits, overloads, and dangerous earth leakage currents. This manual provides essential information for the safe installation, operation, and maintenance of your EKL13 RCBO.
2. Safety Information
WARNING: Electrical work should only be performed by qualified and licensed electricians. Improper installation or handling can result in serious injury or death.
- Always disconnect power at the main supply before installing, servicing, or removing the RCBO.
- Ensure the RCBO's rated current and sensitivity match the requirements of your electrical system.
- Do not operate the device if it appears damaged or faulty.
- Follow all local and national electrical codes and regulations.
- The device housing is made of flame-retardant material for enhanced safety.
3. Setup and Installation
The EKL13 RCBO is designed for easy installation on a standard DIN rail within a distribution box.
3.1. Mounting
- Ensure the main power supply is OFF.
- Locate an available slot on the DIN rail inside your electrical distribution box.
- Align the RCBO with the DIN rail. The video below demonstrates the mounting process.
- Press the RCBO firmly onto the DIN rail until it clicks into place. Ensure it is securely fastened.
3.2. Wiring
Refer to the wiring diagram printed on the device and the image below for correct connections. The EKL13 RCBO features silver alloy contact terminal blocks for large load current and excellent conductivity.
The wiring diagram on the device indicates the following connections:
- 1N (Input Neutral): Connect the incoming neutral wire.
- 1 (Input Line): Connect the incoming live/phase wire.
- 2N (Output Neutral): Connect the outgoing neutral wire to the load.
- 2 (Output Line): Connect the outgoing live/phase wire to the load.
Ensure all connections are tight and secure to prevent loose contacts and potential hazards.
4. Operating Instructions
The EKL13 RCBO is simple to operate with its main handle and test button.
4.1. Switching ON/OFF
- To turn the power ON, push the handle upwards. The indicator window will show RED, indicating the line is connected.
- To turn the power OFF, push the handle downwards. The indicator window will show GREEN, indicating the line is disconnected.
4.2. Test Button
The RCBO is equipped with a 'Test Monthly' button (marked 'T'). This button is crucial for verifying the proper functioning of the residual current protection mechanism.
5. Maintenance
Regular maintenance ensures the continued reliability and safety of your EKL13 RCBO.
5.1. Monthly Test
It is recommended to press the 'Test Monthly' button at least once a month. When pressed, the RCBO should trip (switch to OFF position), indicating that the leakage protection core is functioning correctly. If the device does not trip, it may be faulty and should be inspected and replaced by a qualified electrician.
6. Troubleshooting
The EKL13 RCBO is designed to protect against common electrical hazards. If the device trips, it indicates a fault in the circuit it protects.
- RCBO trips frequently: This indicates a persistent fault such as a short circuit, overload, or earth leakage.
- No power to the circuit: Check if the RCBO is in the OFF position. If it trips immediately after being reset, a fault is present.
- RCBO does not trip when test button is pressed: The leakage protection mechanism may be faulty.
Action: If the RCBO trips, first try to reset it. If it trips again immediately or repeatedly, or if the test button fails to trip the device, do not attempt further resets. Disconnect power to the affected circuit and consult a qualified electrician to identify and rectify the underlying electrical fault.
