Ospel ŁP-4U/m/33 smart switch module, black, IP20, 250V AC, 10A, 71×71×40 mm

Ospel ŁP-4U/m/33 smart switch module is a compact in-wall device for controlling AC mains loads. Housed in a black enclosure with IP20 protection, the unit accepts 250 V AC supply and provides switching capability for currents up to 10 A. Its small footprint of 71×71×40 mm and screwless clamp connectors make it suitable for installations in tight spaces, distribution panels, or behind wall switches where remote or local switching of lighting and small appliances is required within the specified electrical limits.

Advantages

The device combines a compact size with a nominal 10 A switching capacity, enabling control of a wide range of lighting circuits and low-power appliances. Screwless clamp terminals speed up installation and provide secure conductors connection without additional screws. The IP20 enclosure and standard form factor are designed for safe indoor mounting in typical residential and commercial installations where protection against solid objects is required. The unit supports standard AC mains voltage, ensuring compatibility with common electrical systems.

Suitable for

• Switching indoor lighting circuits such as LED, fluorescent or incandescent lamps within the rated current
• Controlling small household appliances and fans within the 10 A limit
• Installation in shallow mounting boxes, behind wall switches, or inside distribution panels
• Retrofit projects where compact modules are needed for remote or local switching

Key specifications

• Operating voltage: 250 V AC
• Nominal switching current: 10 A
• Protection rating: IP20 (indoor use, protection against solid objects)
• Connection type: screwless clamp terminals
• Typical application: in-wall or panel-mounted switch module for lighting and small loads
• Dimensions (W×H×D): 71 × 71 × 40 mm
• Rated for AC mains switching

How to use

Mount the module in an appropriate indoor enclosure or behind a switch plate, ensuring the IP20 rating is suitable for the installation environment. Turn off mains power before connecting conductors. Insert supply and load conductors into the screwless clamp terminals according to the wiring diagram or local wiring standards, verify secure connections, and restore mains power. Use the associated control interface or wiring to operate the module for local switching; if remote control is required, integrate the module with compatible control systems following the system instructions.

Usage recommendations

Observe the 10 A current limit and use the module only for loads within its rated capacity. Ensure installations comply with local electrical regulations and perform wiring and commissioning by a qualified electrician. Avoid exposure to moisture or outdoor environments beyond the IP20 protection level. For long-term reliability, choose loads with inrush currents within acceptable limits and allow adequate ventilation around the module.
