ComPacT NSX100N Circuit Breaker – Reliable Circuit Protection

The ComPacT NSX100N circuit breaker is a single-pole device that combines compact dimensions with high short-circuit breaking capacity. Designed to optimize space in switchboards, it is suitable for both standard and more demanding installations, including those powered by direct current. Its short-circuit breaking capacity of 25kA (at 240VAC 50/60Hz) guarantees the safety and continuity of the installation.

Functionality and Application

Equipped with a thermal-magnetic trip unit (TMD) with a rated current of 40A, the circuit breaker provides comprehensive protection against overloads and short circuits. The TMD trip unit reacts to both long-term loads and sudden current surges, protecting wires and devices from damage. This makes it an ideal solution for protecting circuits powering various types of receivers, including those sensitive to interference. The possibility of mounting on a DIN TH rail (optional) increases installation flexibility.

Key Features and Benefits

• High breaking capacity: 25kA at 240VAC provides effective protection even in the event of large short-circuit currents.
• Thermal-magnetic trip unit (TMD): Provides reliable protection against overloads and short circuits, extending the life of the installation.
• Compact dimensions: Allow for mounting in limited space, which is particularly important in modernized facilities.
• Versatility: Suitable for AC and DC applications, increasing its range of use.
• Trip indication: Built-in indicator allows for quick identification of the circuit breaker status and location of faults.
• Solid construction: Fixed device ensures stability and reliable operation for a long time.
• Compliance with standards: Meets the requirements of international standards (EN/IEC 60947), CCC and EAC, guaranteeing safety of use.
• Screw connection: Provides secure and durable connection of wires.

Additional information: the rated continuous current is 40A, and the overload trip unit adjustment range is 80-100A. The IP40 degree of protection prevents the ingress of solid objects larger than 1mm. Power losses are 5.47W at an operating voltage of 277VAC 50/60Hz.
