The Schneider Electric 18743, an Acti9 NG125L series circuit breaker, provides essential overcurrent protection for low-voltage electrical distribution systems. This single-pole (1P) device is engineered for reliable performance in demanding industrial environments, safeguarding circuits from faults and overloads. Its robust construction ensures consistent operation, making it a critical component in maintaining system integrity.

Technical Details

• Series: Acti9 NG125L
• Poles: 1P (Single Pole)
• Rated Current: 20A
• Tripping Curve: B Curve (typically characterized by lower magnetic trip thresholds, suitable for circuits with low inrush currents)
• Voltage Rating: Verify against manufacturer datasheet for specific AC/DC voltage compatibility.
• Interrupting Capacity: Verify against manufacturer datasheet for specific breaking capacity (kA).
• Terminal Type: Verify against manufacturer datasheet for specific connection type (e.g., screw, cage clamp).
• Mounting Type: DIN rail mount (standard for this series).

Applications & Compatibility

This Schneider Electric circuit breaker is commonly deployed in commercial and industrial settings, including control panels, power distribution units, and machinery enclosures. It is suitable for protecting lighting circuits, socket outlets, and general power distribution circuits where a single-pole protection device is required. Its B tripping curve makes it appropriate for applications with minimal inductive loads.
