The Schneider Electric A9R25440 is a Type A residual current circuit breaker (RCCB) from the Acti9 iID series, engineered for robust protection in electrical systems. This 4-pole device is designed to safeguard personnel and equipment against earth leakage faults, preventing electric shock and fire hazards. Its selective tripping capability ensures that only the affected circuit is interrupted, maintaining the operational continuity of other circuits.

Technical Details

• Series: Acti9 iID
• Poles: 4
• Rated Current: 40A
• Sensitivity: 300mA
• Protection Type: Type A (detects AC and pulsating DC residual currents)
• Tripping Characteristic: Selective (ensures discrimination between upstream and downstream devices)
• Voltage Rating: Verify against manufacturer datasheet for specific voltage class (e.g., 230/400V AC).
• Breaking Capacity: Verify against manufacturer datasheet for specific fault current rating (kA).

Applications & Compatibility

This RCCB is suitable for use in a wide range of industrial and commercial installations, including control panels, motor control centers, and power distribution systems. It is commonly found in applications requiring enhanced safety and reliable fault detection, such as manufacturing facilities, data centers, and building management systems. Ensure compatibility with your specific electrical system design by consulting the manufacturer's documentation.
