The Schneider Electric Acti9 NG125L Miniature Circuit Breaker (MCB) is engineered for reliable overcurrent protection in demanding electrical distribution systems. This single-pole breaker, identified by part number 18747, is a component within the Acti9 NG125L series, designed to safeguard circuits from faults and ensure operational continuity.

Technical details

• Series: Acti9 NG125L
• Type: Miniature Circuit Breaker (MCB)
• Poles: 1
• Rated Current: 50A
• Tripping Curve: B Curve (typically for resistive loads and protection against direct contact)
• Breaking Capacity: Information not explicitly stated in provided text; refer to manufacturer datasheet for specific IEC/UL ratings.
• Voltage Rating: Information not explicitly stated in provided text; refer to manufacturer datasheet for specific AC/DC voltage ratings.
• Terminal Type: Information not explicitly stated in provided text; refer to manufacturer datasheet for specific terminal connection details.

Applications & compatibility

This MCB is suitable for use in residential, commercial, and light industrial electrical panels, providing essential protection for lighting circuits, socket outlets, and small motor loads. Its B-curve characteristic makes it appropriate for applications where the inrush current is relatively low, such as protecting sensitive electronic equipment or standard building wiring.
