4-pole circuit breaker 100A NZMB1-4-A100 265807

4-pole circuit breaker 100A is a reliable protection for electrical installations, designed for both industrial and public building applications. The device is characterized by a high short-circuit breaking capacity, providing effective protection against the effects of overloads and short circuits. Its compact design simplifies installation, and a wide range of trip unit settings allows for precise adaptation to the specifics of the protected installation.

Characteristics and application

NZMB1-4-A100 circuit breaker with a thermal-magnetic trip unit is designed to protect electrical circuits against overloads and short circuits. Its construction based on solid materials guarantees long-lasting and trouble-free operation. The use of a lever as an actuating element in the circuit breaker ensures intuitive operation and quick identification of the device status. Designed for mounting on TH rail (optional), which facilitates integration with existing switchboards. This makes it suitable for various applications – from protecting lighting, through sockets, to more demanding circuits powering machines and equipment.

Advantages and design features

• High short-circuit breaking capacity: 25 kA at 400 V, 50 Hz – guarantees the safety of the installation in the event of a short circuit.
• Overload trip unit setting range: 80…100 A – allows precise adjustment to the load characteristics.
• Solid construction: Fixed device made of high-quality materials ensures durability and reliability.
• Universal mounting: Possibility of mounting on TH rail (optional) and connection using frame clamps increases installation flexibility.
• Protection against overload and short circuit: Thermal-magnetic trip unit effectively protects the installation against damage caused by excessive load or short circuit.
• Protection degree IP20: Provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
• Rated continuous current 100A: Allows safe loading of the circuit with a continuous current of 100A.

This circuit breaker is compatible with the xEnergy system from Eaton Moeller, ensuring easy integration with other electrical infrastructure elements. The setting value in the neutral conductor is set synchronously with the residual current setting value (Ir), which simplifies configuration and ensures optimal protection. This makes the device a comprehensive solution for demanding electrical applications.
