Wall-mounted cross switch Scame Protecta 137.3111 IP66 10A hermetic gray (without box)

Scame Protecta 137.3111 is a hermetic wall-mounted cross (intermediate) switch designed for protected installations where dust and water ingress must be prevented. The unit provides a sealed switching solution with an IP66 degree of protection and a rated switching current of 10 A. Supplied without a mounting box, the gray finish allows integration into industrial, outdoor or damp environment applications while preserving a compact, wall-mounted footprint.

Advantages

The hermetic enclosure ensures reliable performance in environments exposed to dust, jets of water and humidity. The rated IP66 protection class reduces the risk of internal contamination and mechanical deterioration, extending service life in harsh conditions. The cross-switch configuration enables control of a single lighting or load circuit from three or more locations when used in combination with other switches. A 10 A current rating covers typical lighting and small motor control tasks in commercial and industrial settings. The absence of an integrated mounting box provides flexibility for installation using customer-specified enclosures or mounting methods.

Suitable for

• Sealed electrical installations in production halls and workshops
• Outdoor enclosures and shelters exposed to rain or water jets
• Damp rooms, garages and utility spaces requiring dust-tight components
• Lighting circuits controlled from multiple locations via intermediate switching

Key specifications

• Protection rating: IP66 for dust-tight and water-jet protection
• Rated current: 10 A suitable for lighting and small loads
• Mounting type: wall-mounted cross (intermediate) switch
• Finish: gray hermetic enclosure
• Supply: unit supplied without mounting box to allow custom installation

How to use

Install the switch into a suitable sealed mounting box or enclosure that matches the required environmental protection and mounting surface. Ensure correct wiring according to local electrical codes and the cross-switch connection diagram: the intermediate switch is placed between two three-way switches to enable multi-location control. Secure cable entries with appropriate glands or sealed conduits to maintain the IP66 integrity. After wiring, verify correct operation by actuating all associated switches and confirming the load responds from each control point.

Usage recommendations

Use corrosion-resistant glands and suitably rated conduit when routing cables to preserve the hermetic seal. Verify that the chosen mounting box and fasteners maintain IP66 protection after installation. For installations involving higher currents or specific national regulations, consult a qualified electrician to confirm compatibility with the intended load and wiring system.
