- High short-circuit capacity in accordance with North American standards
- Can be integrated with NZM system accessories (actuators, triggers, auxiliary contacts)
- Compact design for easy installation in switchboards with limited space
Application and protective functions
The NZM3-4-AE160-NA circuit breaker is designed to protect conductors, busbars and equipment from the effects of short circuits and overloads in low-voltage networks. It works well in industrial, commercial and infrastructure installations, especially where compliance with North American UL/CSA standards is required. The AE characteristic provides an appropriately selected tripping curve for protection of power lines, distribution circuits and selected power consumers.
The unit can work with a range of accessories dedicated to the NZM3 series, such as front and side drives, rising and undervoltage triggers, auxiliary contacts and modular enclosures. This makes it possible to customize configurations for both simple main switchboards and advanced control and load monitoring systems.
Construction and integration in the NZM3 system
The NZM3-4-AE160-NA power circuit breaker belongs to the NZM3 family of compact apparatuses, suitable for operation in low-voltage switchgear with medium and high rated currents. The 3-pole design allows for use in standard three-phase power systems, with the ability to work with busbars and comb rails.
The unit is designed for simple installation and maintenance. Standardized body dimensions and mounting holes facilitate integration into modular switchgear and enclosure systems from Eaton and other manufacturers. The availability of compatible accessories makes it possible to create systems with manual or motorized operation, as well as to realize remote triggering and signaling of circuit breaker operating states.
