NZMN1-A20 Power switch 3-pole 20A 281231

Power switch – reliable installation protection

This three-pole power switch from Eaton, model NZMN1-A20, is a key element of every safe and efficient electrical installation. Designed to protect circuits with a rated current of up to 20A, it provides effective protection against overloads and short circuits. Its robust construction and high short-circuit breaking capacity (50kA at 400V) guarantee reliable operation even in demanding conditions.

Functionality and application

The NZMN1-A20 switch finds application in a wide range of electrical installations – both in commercial and industrial buildings. It is ideal for protecting circuits powering lighting, sockets, electrical appliances, as well as machines and equipment. Thanks to the possibility of mounting on a DIN rail (optional) and front connection of the main circuits, installation is quick and convenient. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates well the starting of devices with a motor.

Key features and benefits

• High short-circuit breaking capacity: 50 kA at 400 V – ensures effective protection of the installation in the event of a short circuit.
• Overload release setting range: 15-20 A – allows precise adjustment to the needs of a specific circuit.
• Durable construction: Permanently mounted device, made of high-quality materials, guarantees long life and reliability.
• Versatile mounting: Possibility of mounting on a DIN rail or directly on the surface – provides flexibility during installation.
• Front connection of main circuits: Facilitates access and simplifies maintenance work.
• Protection degree IP20: Provides basic protection against contact and ingress of solid objects.
• Rated continuous current (Iu): 100 A - allows safe operation with loads higher than the rated current of the switch.
• Type of actuator: Lever - intuitive operation and quick switching of the switch status.

The NZMN1-A20 switch is a solid solution for professionals and users looking for reliable protection of their electrical installations. Its technical parameters meet stringent safety standards, and its universal application makes it an ideal choice for various electrical projects.
