Schneider A9D11825 Residual Current Circuit Breaker with Overcurrent Protection (RCBO)

Key Features:

1. Protection:
   • Combines the functions of a miniature circuit breaker (MCB) and a residual current device (RCD) in one unit.
   • Provides protection against both overcurrents (overload and short-circuit) and earth leakage currents.
   • Enhances safety by protecting people against electric shocks and preventing electrical fires.
2. Current Rating:
   • Rated at 25A, making it suitable for a range of applications where this current rating is required.
3. Sensitivity:
   • Earth leakage sensitivity of 30mA, which is the standard sensitivity for providing protection against indirect contact and fire hazards.
4. Design:
   • Compact and modular design, which allows for efficient use of space in electrical distribution boards.
   • DIN rail mountable, facilitating easy installation and integration with other modular devices.
5. Breaking Capacity:
   • Designed to handle a specific breaking capacity, ensuring reliable operation in various types of electrical installations.
6. Indicators:
   • Equipped with visual indicators to show the operational status and trip status, making it easier to identify faults.

Applications:

• Residential: Protects electrical circuits in homes, including power outlets, lighting circuits, and appliances.
• Commercial: Suitable for use in office buildings, ensuring the safety of electrical installations and equipment.
• Industrial: Can be used in industrial settings to protect machinery and control circuits from overcurrents and earth leakage.

Benefits:

• Enhanced Safety: Provides comprehensive protection by combining overcurrent and earth leakage protection in a single device, thereby reducing the risk of electric shock and fire.
• Space-Saving: The compact modular design allows for efficient space utilization in distribution boards.
• Ease of Maintenance: Visual indicators provide quick identification of the operational status and any faults, facilitating easier maintenance and troubleshooting.
• Reliability: Constructed with high-quality materials to ensure long-lasting performance and reliable protection.

Considerations:
