Power switch 3-pole 1000A selective NZMN4-VE1000 265770

Power switch – reliable installation protection

This three-pole power switch with a rated current of 1000A is a solid solution for electrical protection in demanding applications. Designed for selectivity, it provides effective protection against overloads and short circuits, minimizing the risk of failures and downtime. Its construction, based on the proven NZM..-VE series from Eaton, guarantees reliability and long-term operation.

Functionality and application

The NZMN4-VE1000 switch is designed for installation in systems with a rated voltage of up to 690V. The C characteristic of the short-circuit release allows for the safe starting of devices with motors that generate high inrush currents. The rated short-circuit breaking capacity of 50kA at 400V ensures effective protection in the event of serious disturbances in the network. Thanks to the possibility of using additional accessories – remote drives, releases or auxiliary contacts – it can be easily adapted to the specific needs of the installation.

Key features and benefits

• High selectivity: enables coordinated operation with other protective elements in the installation, allowing for precise location and isolation of faults.
• Wide range of release settings: adjustment of the overload release range (500-1000A) and short-circuit release (2000-12000A) allows for optimal adaptation to the load characteristics.
• Solid construction: permanently mounted device, made of high-quality materials, ensures durability and resistance to environmental conditions (IP20).
• Installation flexibility: compatibility with LZM/LN and NZM/N series accessories facilitates integration with existing systems.
• Safety: the lack of a built-in short-circuit earth fault protection requires the use of additional protective measures, but allows for flexible adaptation of the protection system to specific needs.
• Ease of use: lever actuator provides intuitive operation and quick identification of the switch status.
• Expandability: optional motor drive enables remote control of the switch.
