The Schneider Electric Acti9 NG125H Miniature Circuit Breaker (MCB) is a robust 2-pole protection device engineered for low-voltage electrical distribution systems. This specific unit, identified by the part number 18716, is rated for 20A and features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents commonly encountered in lighting and small motor applications.

Technical Details

• Series: Acti9 NG125H
• Number of Poles: 2
• Current Rating: 20A
• Tripping Curve: C-curve
• Voltage Rating: Designed for low-voltage applications; specific voltage rating (e.g., 230/400V AC) should be verified against the manufacturer's datasheet for your application.
• Interrupting Capacity: Specific interrupting capacity (kA) should be verified against the manufacturer's datasheet.
• Terminal Type: Screw terminals (verify specific type and size against datasheet).
• Mounting: DIN rail mount (standard for MCBs).

Applications & Compatibility

This Schneider Electric Acti9 NG125H MCB is commonly deployed in residential, commercial, and light industrial settings for the protection of circuits against overloads and short circuits. It is an ideal component for distribution boards, panelboards, and control panels in applications such as lighting circuits, socket outlets, and small appliance circuits where a C-curve is specified for handling typical inrush currents.
