The Schneider Electric Acti9 NG125L miniature circuit breaker (MCB), part number 18757, is engineered for robust protection in low-voltage electrical distribution systems. This 2-pole device is a key component within the Acti9 series, designed for reliable circuit interruption and overload protection in demanding industrial environments. Its construction ensures consistent performance and safety for connected equipment.

Technical details

• Series: Acti9 NG125L
• Number of Poles: 2
• Rated Current: 63 Amps
• Tripping Curve: B Curve (suitable for general purpose applications with low inrush current requirements)
• Voltage Rating: Verify against manufacturer datasheet for specific AC/DC voltage compatibility.
• Interrupting Capacity: Verify against manufacturer datasheet for specific fault current interruption ratings.
• Terminal Type: Verify against manufacturer datasheet for specific connection type and wire gauge compatibility.
• Mounting Type: DIN rail mount (standard for MCBs of this type)

Applications & compatibility

This Schneider Electric MCB is commonly deployed in commercial and industrial facilities to safeguard electrical circuits in panelboards, control cabinets, and distribution boards. It is well-suited for protecting lighting circuits, socket outlets, and general-purpose loads where the characteristic B tripping curve provides appropriate overcurrent protection without nuisance tripping from typical inrush currents.
