Schneider NU322518 | Switch, New Unica, mechanism, 2-pole 1-way, 20A, 2 modules, screw terminals, untreated, IP4X, white

Technical Specifications

The Schneider NU322518 is a two-pole switch, meaning it can simultaneously control or disconnect two live conductors. This double-pole design provides an added layer of safety, especially when handling high-power appliances or circuits. The switch is configured as a one-way mechanism, which means it controls a single circuit from one location.

It is rated for a maximum current of 20 amperes, making it suitable for high-load devices such as water heaters, air conditioners, or heavy-duty lighting systems. The unit size is defined as two modules, giving it a wider frame and allowing for a more stable and durable installation, especially in modular mounting systems.

Connection is made through screw terminals, a reliable and secure method commonly used in industrial-grade electrical fittings. The surface finish of the switch is untreated, which refers to the absence of additional coating or decorative treatment, keeping the product in its standard functional form.

In terms of protection, the switch offers an IP4X rating. This indicates that it is protected against the ingress of solid foreign objects larger than 1 mm, such as fine tools or wires, ensuring operational safety in indoor, dry environments.

The color of the switch is white, which allows it to seamlessly blend into various interior designs and wall finishes.

Key Features

One of the standout features of the Schneider NU322518 switch is its capacity to handle high electrical loads efficiently. The 20A rating makes it a dependable solution for circuits that supply energy to heavy or sensitive appliances.

Its double-pole structure ensures that both the phase and neutral lines can be disconnected, which is crucial for maintenance and user safety, especially in installations where isolating both lines is mandatory.

The design of the switch reflects modern simplicity. The New Unica series is known for its clean lines and stylish look, and the white finish adds a touch of elegance that suits both contemporary and traditional settings.

Installation is made simple thanks to the screw terminal system. This approach provides a secure connection and allows for quick maintenance or replacement when needed, making it suitable for both professionals and experienced DIY users.

The IP4X protection rating enhances durability, particularly in environments where small particles or tools could otherwise pose a risk to the device. This level of protection is more than adequate for indoor electrical systems that require long-lasting performance.

Lastly, the switch is fully compatible with other devices and modules within the Schneider New Unica range, allowing for flexible customization and integration in various configurations.

Applications

The Schneider NU322518 switch is suitable for a wide range of applications. In residential settings, it can be used to control appliances such as water heaters, HVAC systems, or electric pumps. Its ability to manage high current safely makes it especially useful in kitchens, laundry rooms, and utility areas.

In commercial spaces, such as offices or retail environments, the switch offers reliable control for lighting circuits, air conditioning units, or electrical equipment that must be managed individually.

In light industrial environments, the switch can serve as an essential control mechanism for machines or circuits that demand both performance and protection. The two-pole configuration makes it ideal for installations where safety regulations require the disconnection of both conductors.

Additionally, the NU322518 switch can be used in main distribution boards or sub-panels to isolate specific circuits, providing a practical and safe switching solution in more complex electrical systems.
