3-pole circuit breaker 100A BG2 selective NZMN2-VE100 259122

Three-pole circuit breaker with a rated current of 100A is a reliable protection for electrical installations, designed for both construction and industrial applications. Model NZMN2-VE100 is characterized by selectivity, which means that in the event of a short circuit, it will only disconnect the faulty circuit, leaving the rest of the installation in operation. This is crucial for minimizing downtime and quickly locating faults.

Features and application

This circuit breaker is designed to protect against overload and short circuit in circuits with a rated voltage of up to 690V. Its construction allows for mounting on a DIN TH rail (optional) or as a fixed device. Thanks to its high short-circuit breaking capacity (50kA at 400V), it provides effective protection even in demanding conditions. The characteristic of the thermal-magnetic release allows for precise adjustment to the specifics of the protected circuit – the setting range is 50-100A, and the short-circuit release reacts from 1200A. This is important because it avoids unnecessary tripping caused by short-term current surges, e.g. when starting motors.

Advantages for installers and users

• Wide compatibility: The circuit breaker belongs to the NZM/N series, which ensures the availability of a wide range of accessories – remote drives, releases, auxiliary contacts. This makes it easier to adapt the solution to individual project needs.
• High reliability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation of the device.
• Installation flexibility: The possibility of mounting on a DIN TH rail or as a fixed device gives freedom in choosing the installation method.
• Selectivity: Provides effective protection of the installation without unnecessarily disconnecting the entire system in the event of a failure in one of the circuits.
• Setting range: Allows precise tuning of operating parameters to the specifics of the protected circuit and protection against unwanted tripping.
• Compliance with standards: The device meets the appropriate safety standards, which guarantees its correct operation and safety of use (protection degree IP20).

The NZMN2-VE100 circuit breaker is a solid solution for professionals and users who value safety and reliability of electrical installations. Its versatility makes it suitable for a variety of facilities – from residential buildings to industrial plants.
