The Schneider A9N18423 is a 3-pole miniature circuit breaker (MCB) from the Acti9 C120H series, engineered for robust protection and control in electrical distribution systems. This device is designed to safeguard circuits against overcurrents and short circuits, ensuring operational continuity and safety in demanding industrial environments. Its specific configuration makes it suitable for applications requiring precise tripping characteristics.

Technical Details

• Series: Acti9 C120H
• Number of Poles: 3P
• Rated Current: 63A
• Tripping Curve: B Curve (designed for lower inrush currents and higher sensitivity to overloads)
• Rated Short Circuit Breaking Capacity (Icn): Up to 10kA (This specification is derived from the typical capabilities of the C120H series and should be verified against the manufacturer's datasheet for the exact rating of the A9N18423 model.)
• Voltage Rating: Typically 400/415VAC (This is a common voltage rating for this series and should be confirmed with the manufacturer's datasheet.)
• Connection Type: Screw terminals for secure electrical connections.
• Mounting: DIN rail mounting for easy integration into standard electrical panels.

Applications & Compatibility

This miniature circuit breaker is commonly employed in commercial and industrial settings for the protection of lighting circuits, socket outlets, and control circuits where a B tripping curve is specified. It is compatible with standard Acti9 distribution boards and enclosures, facilitating straightforward installation and system expansion. Applications include building electrical installations, control panels for machinery, and power distribution within manufacturing facilities.
