Berker 133111 is a premium self‑extinguishing base plate designed for flush‑mounted electrical installations. It belongs to the renowned Berker series 1930, known worldwide for its robust construction and fire‑resistant properties.
Design & Construction
The 133111 features a single‑gang configuration (1-fach) that fits seamlessly into standard wall cavities. Its compact dimensions—85.5 mm wide, 2.7 mm deep, and 87.5 mm high—ensure a flush finish without protruding edges, providing both aesthetic appeal and safety.
The surface is finished in a matte (frosted) texture that resists fingerprints and enhances the overall visual harmony of any interior design. The material used is a high‑quality thermoset plastic (Duroplast), which offers excellent dimensional stability, chemical resistance, and durability under varying environmental conditions.
All components are free from halogens (Halogen-free), complying with stringent fire safety regulations. This attribute reduces the risk of toxic smoke production during combustion, making it suitable for residential, commercial, and industrial settings where safety is paramount.
Fire‑Resistance Characteristics
The core feature of the Berker 133111 is its self‑extinguishing capability. When exposed to fire, the material automatically ceases combustion once oxygen supply is limited, thereby preventing the spread of flames through the wall cavity. This passive protection mechanism aligns with international fire safety standards and provides an additional layer of security for electrical installations.
Material Quality & Finish
The base plate is manufactured from high‑grade thermoset plastic (Duroplast), ensuring long‑term performance even under thermal stress. The matte finish (frosted surface) not only offers a subtle, modern look but also improves tactile feedback for installers and users alike.
The product’s color is a deep black (RAL 9005), which blends effortlessly with most wall finishes and electrical accessories. Its non‑transparent nature guarantees that the internal components remain concealed, maintaining a clean and professional appearance.
Installation & Compatibility
Designed for flush mounting, the 133111 integrates smoothly into standard wall cavities without requiring additional framing or support structures. Its slim profile (2.7 mm depth) allows it to fit behind most electrical boxes and switches, ensuring a neat installation that meets both functional and aesthetic requirements.
The base plate is compatible with a wide range of Berker and Hager switches, sockets, and other accessories. Whether you are upgrading an existing system or installing new circuitry, the 133111 provides a reliable foundation for safe electrical connections.
