Bals 2155 plug TE m.MULTI-GRIP cable gland 63 A 5p 400 V 6h IP44 content_copy

The Bals plug type 2155 is an industrial connector of CEE form, designed for use in industrial and commercial installations. It features a rated current of 63 A and a pole count of 5 (3P+N+PE), with voltage according to EN 60309-2 at 400 V (50/60 Hz). The identification colour red (RAL 3000) indicates the voltage class and enables clear identification during operation. The time position is 6, defining the plug's position within the connector system. The protection rating IP44 ensures protection against solid objects larger than 1 mm and against splashing water from any direction, enabling use in indoor environments and slightly damp conditions.

Applications
This plug is designed for use in industrial installations, workshops, construction sites, and other environments where a safe and reliable power supply with high performance is required. The construction complies with IEC and EN 60309-2 standards applicable to CEE connectors. The red-marked voltage class 400 V (200/346 – 240/415 V~) makes it particularly suitable for three-phase installations operating at a nominal voltage of 400 V. The IP44 protection rating makes it suitable for indoor use and areas with occasional moisture, but not for permanent wet conditions or direct water exposure.

Functions and Equipment in Detail
The plug features a screw clamp technology as frame terminals, enabling a secure and durable connection with cables. The maximum conductor cross-section is 16.0 mm², allowing connection with medium to large conductors. Cable entry is achieved via an integrated cable gland equipped with MULTI-GRIP technology. This gland ensures secure cable fixation and prevents strain on the connection. The integrated strain relief protects the electrical contacts from mechanical stress. The cable gland is designed for cables with a minimum diameter of 16 mm up to a maximum diameter of 36 mm.

Technology Explained Simply
The contact carrier is made of a high-temperature-resistant material capable of withstanding thermal stress. The contacts themselves are made of brass and nickel-plated, ensuring high electrical conductivity and corrosion resistance. The housing is made of polyamide, a robust plastic that withstands mechanical stress and temperature fluctuations. The housing parts are connected without screws via a latch slider, ensuring a secure connection. Opening the housing is only possible with a screwdriver, preventing accidental disconnection. The device colours are clearly defined: the collar is red (RAL 3000), the operating slider is black (RAL 9005), and the housing cap and cable gland are dark grey (RAL 7012).

Compatibility and Accessories
The plug is compatible with matching couplers, particularly the TE m.MULTI-GRIP cable gland 63 A 5p 400 V 6h IP44, also available in the range. This coupler enables a secure and quick connection with other CEE connectors of the same standard. The combination of plug and coupler forms a complete connector system designed for industrial use. Using accessories from the same system ensures uniform protection rating, current rating, and mechanical fit.

Mounting and Installation
Mounting is done via the integrated cable gland, which securely fixes the cable in the housing. The screw clamps allow for easy and secure conductor connection. The screwless connection of housing parts is secured by a latch slider, which can only be opened with a screwdriver. This prevents accidental opening and increases safety during operation. The device dimensions are 234 mm (height), 97 mm (width), and 98 mm (depth), which should be considered when planning mounting surfaces.

Advantages in Operation
The plug offers high mechanical and electrical reliability. The use of nickel-plated brass contacts ensures low contact resistance and high conductivity. The MULTI-GRIP cable gland with integrated strain relief extends the connection's lifespan and protects against mechanical damage. The IP44 protection rating allows use in damp environments without compromising electrical safety. The clear identification colour red (RAL 3000) simplifies identification during operation and contributes to safety. The screwless assembly of housing parts reduces installation effort and increases operational safety.
