Ospel ŁNH-3N/00 Hermetic Single Staircase Switch, 16A 250V, IP44, White

The Ospel ŁNH-3N/00 is a high-quality single staircase switch engineered for reliable performance in challenging environments. This hermetic switch is designed to provide secure control of lighting circuits, particularly in areas where moisture and dust protection are essential. With its clean white finish and robust build, it integrates seamlessly into various residential and commercial electrical systems, ensuring long-term operational safety and durability.

Advantages

The primary advantage of this switch is its IP44 ingress protection rating, which effectively shields internal components from splashing water and solid objects. This makes it an ideal choice for installation in damp locations such as garages, basements, workshops, or covered outdoor areas. The device supports a high nominal current of 16A, allowing it to handle significant electrical loads safely. Furthermore, the use of reliable screw terminals ensures a secure and stable connection for electrical wiring, reducing the risk of loose contacts over time.

Suitable for

• Controlling lighting in staircases and hallways
• Installation in damp indoor environments like basements or laundry rooms
• Outdoor use in sheltered areas such as porches or garages
• Residential and commercial electrical infrastructure

When it may not be suitable

This switch is not intended for direct exposure to heavy rain or water jets, as it is rated IP44 rather than fully waterproof. It should not be installed in environments where it may be submerged in water or exposed to extreme chemical vapors that could degrade the housing material.

• Voltage: 250V
• Maximum load: 3520W
• Ingress protection: IP44
• Connection type: Screw terminals
• Dimensions: 65 mm x 46 mm x 70 mm

How to use

The Ospel ŁNH-3N/00 should be installed by a qualified electrician in accordance with local electrical regulations. Before installation, ensure the power supply is disconnected at the main circuit breaker. The switch is designed for surface mounting. Use the screw terminals to connect the phase and load wires according to the staircase switching diagram. Once the wiring is secure, mount the housing firmly to the wall surface, ensuring the gasket is properly seated to maintain the IP44 seal.

What to consider before purchase

• Verify that the IP44 rating meets the specific environmental requirements of your installation site.
• Ensure the total load of the connected lighting circuit does not exceed the 3520W limit.
• Check that the surface mounting style is compatible with your wall structure.
• Confirm that the wiring configuration supports a staircase switching setup.

Usage recommendations

Always inspect the housing and seals for any damage before installation to ensure the hermetic properties remain intact. Periodically check the screw terminals for tightness if the switch is located in an area subject to vibration.
