The socket 106457 from Vossloh-Schwabe is a ceramic socket for low-voltage halogen lamps with the GU 5.3 plug system. It serves as an electrical connection point for halogen lamps in the low-voltage range, typically used in applications with 12 V operating voltage. The socket is designed for use in luminaires and lighting systems where secure and thermally stable lamp fixation is required. The ceramic construction ensures high heat resistance and electrical insulation, which is particularly important when using halogen lamps with high operating temperatures.

Socket type and design

The socket is designed as a partially enclosed version, where the lamp holder spring remains visible and the electrical connection is made via the contacts of the GU 5.3 plug system. The socket features clearance holes for screws with the ST2,5 profile, used for mounting in luminaires or enclosures. The usable cable length is 140 mm, providing sufficient space for wiring within the luminaire. The cable has a cross-section of 0.75 mm², which is sufficient for most low-voltage applications and ensures safe current transmission.

Technology explained simply

The GU 5.3 socket is a standard plug system for small halogen lamps, where the designation GU" stands for "Gesamte Umschließung (complete enclosure) and the number 5.3 indicates the distance between the two contacts in millimeters. The ceramic socket offers better heat dissipation and electrical insulation compared to metallic variants, increasing safety. The partially enclosed construction allows for easy installation and maintenance, as the lamp can be inserted and removed easily without having to dismantle the entire luminaire.

Compatibility and accessories

The socket is specifically designed for low-voltage halogen lamps operated at 12 V. It is compatible with lamps using the GU 5.3 plug system. The socket can be used in various luminaires and lighting systems, particularly in applications requiring a stable and heat-resistant socket.

Mounting and installation

Mounting is done by securing the socket in the luminaire using ST2,5 screws, inserted into the designated clearance holes. The cable with a 0.75 mm² cross-section can be directly connected to the electrical supply. The usable cable length of 140 mm allows for flexible wiring within the luminaire. The socket is intended for use in permanently installed luminaires, and mounting should be performed by qualified electricians to ensure safety.

Advantages in operation

The ceramic socket offers high thermal stability, increasing lamp life and safety. The partially enclosed design facilitates maintenance, as the lamp can be replaced without tools. The use of 0.75 mm² cable ensures reliable power supply without overloading the cable. The socket is designed for use in low-voltage installations, making it suitable for many lighting systems, particularly in residential and commercial areas.
