Military model

The Bals coupling TLS with MULTI-GRIP cable gland, type 310364, is an industrial CEE coupling designed for use in demanding environments. It is rated for a nominal current of 32 A and a nominal voltage of 400 V (50/60 Hz), and features a 5-pole contact configuration (3P + N + PE). The pin spacing is 6h, enabling unambiguous alignment in the plug system. The coupling is equipped with IP67 protection rating, meaning it is dust-tight and temporarily waterproof—suitable for outdoor use or in damp industrial environments. The identification color red (RAL 3000) enables visual identification and complies with standard EN 60309-2.

Applications
This coupling is designed for industrial applications, particularly in environments with high mechanical stress, moisture, or dirt. It is suitable for construction sites, production facilities, mobile machinery, or temporary power supplies, where a secure and weather-resistant connection is required. The IP67 protection rating ensures high reliability under harsh conditions.

Features and Equipment in Detail
The coupling features a one-piece housing construction made of polyamide, known for its high mechanical strength and heat resistance. The contacts are made of nickel-plated brass, ensuring good electrical conductivity and corrosion resistance. The contact carrier is also made of polyamide. Connections are made via screw terminals, ensuring a secure and durable contact. The maximum conductor cross-section is 6.0 mm², enabling use with standard industrial cables.

Technology Explained Simply
The MULTI-GRIP cable gland allows for secure and easy cable fixation in the device. It includes integrated strain relief to minimize mechanical stress on the conductors and the connection. The gland is suitable for cables with a minimum diameter of 11 mm up to a maximum diameter of 23 mm. The cable gland and bayonet ring are gray (RAL 7035), while the housing and hinged cover are red (RAL 3000). The plug orientation is straight, enabling direct connection.

Compatibility and Accessories
The coupling is designed for use with compatible CEE plugs and couplings in the 5-pole system (3P + N + PE) with 6h pin spacing. It is compatible with other devices meeting the same standard (EN 60309-2) and protection rating (IP67). The MULTI-GRIP gland is specifically developed for the Bals product line and ensures secure cable fixation. No specific accessories are mentioned in the sources.

Installation and Mounting
Installation is done via screw terminals, designed for connecting conductors. The cable gland is attached to the cable end and screwed into the device, with integrated strain relief reducing mechanical stress. The coupling is designed for direct mounting on a wall or panel, with device dimensions of 190 mm (height) × 101.5 mm (width) × 106 mm (depth).

Operational Advantages
The coupling offers high mechanical and electrical reliability. The IP67 protection rating protects against dust and temporary water contact, enhancing operational safety. Screw terminals enable secure and maintenance-friendly connections. The MULTI-GRIP gland with strain relief reduces the risk of cable breakage or contact loss due to mechanical stress. The clear identification color red (RAL 3000) facilitates easy identification in the system.
