1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of the Schneider Electric Acti9 IC60N Miniature Circuit Breaker, model A9F74206. This device is designed to protect electrical circuits from overcurrents, which can result from overload or short circuit. Adherence to these instructions is crucial for ensuring the safety of personnel and the proper functioning of the electrical system.
2. Safety Information
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified and authorized personnel. Failure to follow these instructions can result in serious injury or death.
- Always disconnect power at the main supply before working on electrical circuits or equipment.
- Use appropriate personal protective equipment (PPE).
- Verify that the circuit breaker ratings (voltage, current, breaking capacity) are suitable for the application.
- Ensure all connections are tight and secure to prevent overheating and arcing.
- Do not bypass or modify the circuit breaker.
- Comply with all local and national electrical codes and regulations.
3. Product Overview
The Schneider Electric Acti9 IC60N A9F74206 is a 2-pole miniature circuit breaker with a 6A current rating and C-curve tripping characteristic. It is designed for protection against overloads and short circuits in residential, commercial, and industrial installations.
Figure 1: Schneider Electric Acti9 IC60N Circuit Breaker A9F74206. This image shows the front view of the white 2-pole circuit breaker with the Schneider Electric logo, IC60N model designation, and "Made in France" marking. The two toggle switches are visible, currently in the "OFF" position.
Key Features:
- Model: A9F74206
- Poles: 2P (2-Pole)
- Current Rating: 6 Amperes (6A)
- Tripping Curve: C (for general applications, protecting against overloads and short circuits in circuits with moderate inrush currents)
- Frequency: 50/60 Hz
- Mounting Type: Plug-In Mount (typically DIN rail mountable)
- Origin: Made in France
4. Setup and Installation
Installation must be performed by a qualified electrician in accordance with all applicable electrical codes and standards.
Installation Steps:
- Power Disconnection: Ensure that the main power supply to the electrical panel or distribution board is completely disconnected and locked out/tagged out to prevent accidental re-energization.
- Mounting: The IC60N circuit breaker is designed for DIN rail mounting. Snap the circuit breaker onto the DIN rail securely.
- Wiring:
- Connect the incoming phase conductors to the top terminals of the circuit breaker.
- Connect the outgoing load conductors to the bottom terminals of the circuit breaker.
- Ensure correct polarity and phase sequence if applicable.
- Tighten terminal screws to the specified torque (refer to product markings or technical data sheet, typically 3.5 Nm for this model).
- Verification: Double-check all connections for tightness and correct wiring. Ensure no bare wires are exposed.
- Panel Closure: Close the electrical panel cover securely once installation is complete.
- Power Restoration: Restore power to the main supply.
5. Operating Instructions
Switching ON/OFF:
- To Switch ON: Push the toggle switch(es) upwards to the "ON" position. The circuit is now energized.
- To Switch OFF: Push the toggle switch(es) downwards to the "OFF" position. The circuit is now de-energized.
Tripping and Resetting:
If an overload or short circuit occurs, the circuit breaker will automatically trip, moving the toggle switch(es) to an intermediate or "TRIPPED" position (often between ON and OFF, or fully OFF depending on the mechanism). This indicates a fault in the circuit.
- Identify and Rectify Fault: Before resetting, identify and correct the cause of the trip (e.g., remove overloaded appliances, fix short circuits).
- Reset: First, push the toggle switch(es) fully to the "OFF" position, then push it upwards to the "ON" position. If the breaker immediately trips again, a fault still exists. Do not repeatedly reset a tripping breaker without addressing the underlying issue.
6. Maintenance
The Schneider Electric Acti9 IC60N circuit breaker is generally maintenance-free under normal operating conditions. However, periodic inspections by qualified personnel are recommended.
- Visual Inspection: Periodically inspect the circuit breaker for any signs of physical damage, discoloration, or loose connections.
- Cleaning: If necessary, clean the exterior of the circuit breaker with a dry, lint-free cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
- Functional Check: Occasionally, manually switch the circuit breaker OFF and ON to ensure smooth operation of the toggle mechanism.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Circuit breaker trips frequently. | Overload in the circuit, short circuit, or faulty appliance. |
|
| Circuit breaker does not reset. | Persistent fault in the circuit (overload or short circuit) or internal damage to the breaker. |
|
| Circuit breaker feels hot. | Loose connections, excessive load, or internal fault. |
