ComPacT NSXm160B Circuit Breaker 25kA AC 4P4R 160A TMD ELINK

The Schneider Electric ComPacT NSXm160B 25kA AC 4P4R 160A TMD ELINK circuit breaker is a compact, efficient, and highly reliable solution designed to protect low-voltage electrical systems in industrial and commercial applications. With a breaking capacity of 25kA at 415V AC, this 4-pole (4P4R) circuit breaker is optimised to offer robust protection in critical conditions, ensuring continuity of power supply and the safety of connected equipment.

The ComPacT NSXm160B is one of the smallest moulded case circuit breakers on the market, with dimensions of only 108 mm wide, 137 mm high, and 80 mm deep. This compact design allows for easy integration into electrical cabinets and power distribution systems, occupying minimal space without sacrificing protection capacity. Its reduced size is ideal for applications where space is limited and high-performance protection is required.

This model incorporates Schneider Electric's innovative Everlink technology, ensuring a stable and secure connection, even in environments with vibrations or thermal fluctuations. Everlink reduces the risk of loose or faulty connections, enhancing system safety and long-term operational reliability. Additionally, the breaker offers the possibility of both DIN rail and plate mounting, providing additional flexibility in installation, adapting to different electrical panel configurations.

The thermal-magnetic (TMD) control unit incorporated in the ComPacT NSXm160B provides adjustable protection against thermal overloads and short circuits, ensuring that the electrical system is protected from current variations that could damage equipment or compromise installation safety. This control unit combines thermal protection with a long delay (L) for overloads, magnetic protection with a short delay (I) for short circuits, and instantaneous protection (G), guaranteeing a fast and precise response to any electrical fault.

Key Technical Specifications:

• Breaking Capacity (Icu): 25kA at 415V AC, with additional capacities of 50kA at 220/240V AC and 20kA at 440V AC, allowing effective protection at different voltage levels.
