The Schneider Electric 18646 is a Miniature Circuit Breaker (MCB) from the Acti9 NG125N series, engineered for robust protection in low-voltage electrical distribution systems. This 3P+N configuration breaker is designed to safeguard against overcurrent conditions, including both short-circuit and overload faults, ensuring operational continuity and personnel safety in three-phase applications with a neutral conductor.

Technical Details

• Series: Acti9 NG125N
• Configuration: 3 Pole + Neutral (3P+N)
• Rated Current: 80A
• Interrupting Capacity: The NG125N series typically offers a high interrupting capacity, suitable for demanding industrial environments. Verify specific breaking capacity (kA) against the manufacturer's datasheet for your application's fault current requirements.
• Trip Curve: Standard trip curves are available within the NG125N series; confirm the specific curve (e.g., C, D) for the 18646 model to match your load characteristics.
• Voltage Rating: Designed for standard low-voltage AC distribution systems. Confirm the precise AC voltage rating (e.g., 230/400V) from the manufacturer's documentation.
• Terminal Type: Screw terminals are standard for secure connections.
• Mounting: DIN rail mountable for easy integration into standard electrical enclosures.

Applications & Compatibility

This Schneider Electric MCB is commonly deployed in industrial control panels, power distribution boards, and machinery for applications such as manufacturing lines, HVAC systems, and building services. Its 3P+N configuration makes it ideal for protecting three-phase loads that also require a neutral connection, including motors, pumps, and lighting circuits.
