Smart switch Ospel ŁP-4R/m/27 — 16 A, 250 V AC, IP20, 71×71×42 mm

Ospel ŁP-4R/m/27 is a smart wall switch suitable for residential and light commercial electrical installations. The unit provides switching for lighting and small electrical loads at mains voltage, rated for 250 V AC with a nominal current of 16 A. With compact dimensions of 71×71×42 mm and an IP20 protection rating, the device is intended for standard indoor environments and fits common mounting boxes. Screwless clamps simplify wiring while ensuring secure conductor connection.

Advantages

The switch combines a compact form factor with a 16 A switching capacity that handles typical lighting circuits. IP20 protection makes it appropriate for indoor use where solid object protection is required. Screwless clamps enable quicker installation and reduce the need for additional tools. The product is designed to integrate into standard mounting systems, offering reliable mechanical and electrical performance for everyday switching tasks.

Suitable for

• Controlling indoor lighting circuits in homes and apartments
• Switching small resistive or inductive loads such as lamps and small fans
• Use in corridors, living rooms, kitchens and other dry indoor spaces
• Replacement or upgrade of standard wall switches in residential installations

Key specifications

• Rated voltage: 250 V AC
• Nominal output current: 16 A
• Rated switching type: 16AX (suitable for resistive and inductive loads within rating)
• Protection class: IP20 (indoor use, protection against solid objects ≥12 mm)
• Terminal type: screwless clamps for conductor connection
• Dimensions: 71 × 71 × 42 mm (width × height × depth)
• Mounting: fits standard flush mounting boxes

How to use

Install the switch in a standard flush mounting box following local electrical codes and safety regulations. Ensure power is switched off before making connections. Insert conductors into the screwless clamps according to the wiring diagram and confirm secure retention. After wiring, restore power and test switching operation with the intended load. Use the device only in dry indoor environments compatible with IP20 protection.

Usage recommendations

For reliable operation, match the connected load to the 16 A rating and avoid installing the switch in areas exposed to moisture or dust beyond IP20 limits. Verify compatibility of connected lamps or devices with 16AX switching characteristics. If installing in multi-gang plates or near heat sources, allow appropriate spacing and follow mounting instructions to prevent overheating and ensure long-term performance.
