The Schneider Electric A9N18344 is an Acti9 C120N miniature circuit breaker (MCB) designed for reliable overcurrent protection. This low-voltage, multistandard device is engineered for applications requiring precise tripping characteristics, commonly found in residential electrical panels and small commercial distribution systems.

Technical details

• Series: Acti9 C120N
• Type: Miniature Circuit Breaker (MCB)
• Tripping Curve: B curve, providing sensitive protection against overloads and short circuits with a lower magnetic trip threshold compared to C or D curves.
• Voltage Rating: Suitable for low-voltage applications; specific voltage class should be verified against manufacturer datasheet for precise AC/DC ratings.
• Interrupting Capacity: Specific interrupting capacity (kA) should be verified against manufacturer datasheet.
• Number of Poles: Typically 1, 2, 3, or 4 poles; specific configuration for A9N18344 should be verified against manufacturer datasheet.
• Terminal Type: Screw terminals for secure connection; specific wire gauge compatibility should be verified.
• Mounting: Designed for DIN rail mounting.

Applications & compatibility

This Schneider Electric MCB is suitable for protecting circuits in building installations, control panels, and machinery where sensitive overcurrent detection is paramount. It is commonly integrated into power distribution boards, control cabinets for automation equipment, and branch circuit protection in commercial spaces.
