## Long description

ELKO‑BIS terminal control connector 4‑hole 57×57×57 mm galvanized 4.1 OC is a compact metal junction element designed for control and signaling wiring in electrical installations. With external dimensions of 57×57×57 mm and a galvanized finish, this connector provides a corrosion‑resistant enclosure for terminating cables and creating reliable connection points in both indoor and protected outdoor environments. The product is intended for applications where a small, robust, and long‑lasting junction box is required to organize control conductors and signal lines.
Advantages
The galvanized steel construction ensures enhanced corrosion resistance and mechanical strength compared with non‑protected metal boxes. A compact cubic form factor optimizes space in crowded mounting locations and simplifies integration with existing conduit and fixture layouts. The four terminal entry points provide organized routing for multiple control or signal conductors, reducing cable stress and facilitating safe terminations. The product's design supports quick installation and service access while maintaining a secure enclosure for connections.
Suitable for
 Termination of low‑voltage control and signaling circuits
 Compact junctions behind control panels or equipment
 Protected outdoor or indoor environments where corrosion resistance is needed
 Installation points requiring a small, metal enclosure for conductor routing
Key specifications
 Material: galvanized metal
 External dimensions: 57 × 57 × 57 mm
 Configuration: 4 hole / 4 entry points for conductors
 Intended use: control and signalling wiring junction
 Suitable locations: indoor and protected outdoor installations
How to use
Mount the terminal control connector at the chosen location using appropriate fasteners for the supporting surface, ensuring it is fixed securely and level. Route control and signal conductors through the designated entry points, strip insulation to the required length and make terminations with suitable terminal blocks or connectors compatible with the enclosure. Re‑check conductor routing to avoid sharp bends and ensure strain relief where cables enter. Close and fasten the cover to maintain the protective properties of the galvanized enclosure and to prevent accidental contact with live parts.
Usage recommendations
Use the connector within its intended ambient conditions: protected outdoor areas or indoor environments without direct exposure to heavy water ingress. Select compatible terminal blocks and sealing methods if the installation may face humidity or condensation. Follow local electrical codes and practices for conductor sizing, grounding, and protective measures when integrating the connector into control and signaling systems.
