Electrical switch Kontakt-Simon 7700251-039 — metal housing, 250 V AC, 10 A, IP20/IP44, 75×40 mm

Kontakt-Simon 7700251-039 is a compact electrical switch in a metal housing intended for AC installations. Rated for 250 V AC and a nominal current of 10 A, the unit is suitable for switching lighting circuits and small loads in residential and light-commercial environments. The switch measures 75×40 mm and weighs approximately 59 g; it is designed to be installed where a robust metal enclosure and basic splash protection are required.

Advantages

The metal housing provides increased mechanical protection and improved durability compared with standard plastic-bodied switches. Two protection grades are available depending on installation: IP20 for typical indoor mounting and IP44 where splash protection is needed. Compact dimensions allow installation in confined spaces and standard wall boxes, while the 10 A nominal current rating covers most lighting and small-appliance switching needs. The product’s straightforward electrical ratings (250 V AC, 10 A) make integration into existing AC installations simple for electricians and installers.

Suitable for

• Switching lighting circuits in homes and apartments
• Control of small loads such as fans or low-power appliances
• Use in kitchens, bathrooms or other areas requiring splash protection when mounted accordingly
• Applications where a metal housing is preferred for mechanical robustness

Key specifications

• Rated voltage: 250 V AC
• Nominal current: 10 A
• Protection ratings: IP20 (standard), IP44 (splash protection for appropriate mounting)
• Housing material: metal
• Dimensions (W×D): 75 × 40 mm
• Weight: approximately 59 g

How to use

Install the switch following local electrical codes and safety practices. Ensure the supply is turned off before connecting conductors. Mount the unit in a compatible box or panel, providing the appropriate sealing or gaskets if IP44 protection is required. Connect line and load conductors to the switch terminals according to the circuit design, confirm secure mechanical fixation of the metal housing, and restore power to test switching function. Regularly inspect connections and the housing for signs of wear or corrosion in service environments.

Usage recommendations

Use the switch within its rated voltage and current limits, and select the mounting arrangement that provides the required IP protection for the installation location. For installations in damp areas where splash protection is needed, ensure correct sealing to achieve the IP44 rating. Consult a qualified electrician for installation in complex or regulated environments.
