The Schneider Electric NG125N, identified by part number 18671, is a 3-pole miniature circuit breaker engineered for robust protection of electrical circuits. This breaker is specifically designed to safeguard against damaging short circuits and overloads, making it a critical component in industrial power distribution systems. Its construction and specifications are optimized for environments requiring reliable circuit interruption and fault containment.

Technical details

• Series: NG125N
• Poles: 3
• Rated Current: 125A
• Tripping Curve: D Curve, suitable for applications with high inrush currents such as motors or transformers.
• Breaking Capacity: While not explicitly stated in the provided information, D-curve breakers typically offer higher breaking capacities suitable for industrial fault conditions. Buyers should verify the specific breaking capacity (e.g., kA rating) against the manufacturer's datasheet for their application's requirements.
• Voltage Rating: The voltage rating is not explicitly provided in the existing information. Buyers are advised to consult the Schneider Electric datasheet for the NG125N series to confirm the applicable AC and DC voltage ratings.
• Terminal Type: Standard screw terminals for secure connection.
• Mounting: Designed for DIN rail mounting, facilitating easy installation in standard electrical enclosures.

Applications & compatibility

This Schneider Electric circuit breaker is commonly deployed in industrial control panels, motor control centers, and power distribution boards. Its D-curve characteristic makes it particularly well-suited for protecting inductive loads such as motors on conveyor systems, pumps, fans, and machine tools where significant starting currents are expected. It ensures reliable operation by preventing nuisance tripping while providing essential overcurrent protection.
