Power switch 3-pole 100A BG2 NZMH2-A100 259099

3-pole power switch 100A is a reliable protection for electrical installations, generators and motors. The device is designed to protect against the effects of overloads and short circuits, ensuring safe and stable system operation. The switch construction, based on proven Eaton technology, guarantees high resistance to environmental conditions and long-term operation.

Characteristics and application

NZMH2-A100 switch with characteristic C allows for a slower response to short current surges, which is particularly important when starting devices with motors – this avoids unnecessary tripping of the circuit. The rated continuous current of 100A makes it an ideal solution for circuits with medium loads. The short-circuit capacity of 150kA at 400V provides effective protection in the event of a serious failure. This switch is used in main distribution boards, sub-distribution boards, and in industrial and construction installations.

Construction and mounting

The NZMH2-A100 switch has three poles and is designed for mounting on a TH rail (optional) or as a fixed device. Connection of the main contacts is made using screw connections, which ensures a secure and durable electrical connection. The device is characterized by a compact design, making it easy to install even in tight spaces. The availability of remote drives and additional accessories (auxiliary contacts, release devices) allows the switch to be adapted to individual installation needs. A wide range of accessories from the LZM/LN and NZM/N series ensures compatibility with other Eaton devices.

Key features and benefits

• High short-circuit capacity (150kA): provides effective protection against the effects of short circuits, minimizing the risk of damage to the installation and equipment.

• Overload release setting range (80-100A): allows precise adjustment to the circuit load, preventing unnecessary tripping.

• Characteristic C: ideal for circuits with devices with high inrush current (e.g. motors).

• Expandability: a wide selection of accessories allows the switch to be adapted to specific application requirements.

• Solid construction: guarantees long-lasting and reliable operation in harsh industrial conditions.

• Compliance with standards: ensures safety and compliance with applicable regulations.

• Flexible mounting: the possibility of mounting both on a TH rail and as a stationary device facilitates integration with various types of switchboards.
