Vossloh-Schwabe 109285 plastic screw ring E27 black H=15 mm D=55 mm content_copy

The Vossloh-Schwabe E 27 thermoplastic lamp holder, type 109285, is a plastic screw-ring holder for incandescent lamps and other luminaires with an E 27 base. It serves as a mounting component in luminaire and lamp constructions where a secure and insulating fixation of the lamp base is required. The holder is made of thermoplastic, ensuring high electrical insulation and heat resistance. The black lacquered surface ensures unobtrusive integration into various luminaire constructions.

Lamp Holder Type
This holder is specifically designed for E 27 bases, which have a diameter of 55.0 mm and a height of 15 mm. These dimensions correspond to the standard for medium-sized incandescent lamps and energy-saving lamps. The sleeve terminals allow for a secure electrical connection to the luminaire cable, with the terminals rated for a nominal voltage of 250 V and a nominal current of 4 A. These values are typical for use in household and commercial luminaires.

Material and Construction
The holder is made of thermoplastic, a plastic suitable for its electrical insulation properties and resistance to mechanical stress and temperature variations. The black-coloured surface is not only aesthetic but also functional, as it is UV-resistant and resistant to everyday dirt. The shape of the screw ring ensures a stable fixation of the lamp base within the lamp holder.

Applications
The holder is used in various luminaire designs, particularly in luminaires intended for indoor use. It is suitable for applications in residential and commercial spaces where a reliable and secure fixation of the lamp base is required. The holder is not intended for use in damp or wet environments, as no specific protection rating (e.g. IP) is specified.

Compatibility and Accessories
The holder is compatible with all luminaires that feature an E 27 base. It can be used in combination with various luminaire constructions, particularly in facade luminaires, ceiling luminaires, or wall luminaires requiring an E 27 holder. The holder is supplied as a single unit and is not connected to additional components such as cables, switches, or lamps.

Installation and Mounting
Mounting is performed by inserting the screw ring into the designated opening of the luminaire and securing the lamp base using the integrated sleeve terminals. The terminals allow for an easy and secure connection to the luminaire’s electrical supply. No additional tools or mounting aids are required, as the holder is mechanically installed into the luminaire.

The holder is designed for use in electrical installations with an operating voltage up to 250 V and a current up to 4 A. Use in installations with higher values is not intended and could lead to overload. The holder is not suitable for use in explosive environments or areas with aggressive chemicals, as no specific protective measures or material compositions are specified for such conditions.

Operational Advantages
The holder provides a reliable and secure fixation of the lamp base, preventing accidental dislodging or loosening of the lamp. The thermoplastic insulation protects against electrical contact and increases safety during use. The black-coloured surface blends into most luminaire constructions and avoids visual distractions. The holder is maintenance-free and does not require regular inspection, provided it is not mechanically damaged.
