The Bals plug QUICK-CONNECT type 2130 is an industrial connector for use in electrical installations with a rated voltage of 400 V (50/60 Hz) and a rated current of 16 A. It features a 4-pole configuration (3P+PE) and is marked red according to EN 60309-2, corresponding to RAL number 3000. The clock position is 6, defining the positioning of the plug contacts within the connector. The plug is designed for use in environments with a protection rating of IP44, meaning it is protected against solid foreign objects (minimum 1.0 mm) and splashing water from any direction. This makes it suitable for use in indoor areas as well as in lightly moist outdoor areas where occasional splashing may occur.

Applications

The plug is designed for industrial applications, particularly for machines, tooling systems, mobile equipment, and temporary power supplies. It is suitable for installations requiring a secure and quick electrical connection without the need to manually tighten screw connections. The red identification color indicates a specific voltage category according to CEE form standardization, ensuring clear assignment and preventing incorrect connections.

Functions and Equipment in Detail

The plug features a screwless spring clamp technology with socket spring clamps, enabling fast and secure cable connection. The maximum allowable conductor cross-section is 2.5 mm². Cable entry is via a MULTI-GRIP cable gland, which provides integrated strain relief. This design protects the cable from mechanical stress and prevents disconnection due to pulling forces. The gland is designed for cables with a minimum diameter of 8 mm up to a maximum diameter of 18 mm.

Technology Explained Simply

The contacts are made of bare brass, ensuring high electrical conductivity and good corrosion resistance. The contact carrier is made of polyamide, a thermoplastic material with high mechanical strength and heat resistance. The housing is also made of polyamide, providing high insulation capability and mechanical stability. The housing parts are connected without screws and are secured by a latching mechanism. Opening the housing is only possible with a screwdriver, preventing accidental opening and enhancing safety.

Compatibility and Accessories

The plug is compatible with the matching coupling QC 3130, which is also equipped with MULTI-GRIP glands. This combination enables a secure and quick connection between two devices or between a device and a power supply. The coupling meets the same technical specifications as the plug (16 A, 4-pole, 400 V, IP44) and is therefore directly combinable.

Mounting and Installation

Installation is performed by inserting the cable into the cable gland and then tightening it. The spring clamps ensure automatic securing of the conductor. The plug orientation is straight, allowing for direct connection. The dimensions of the plug are 146 mm (height), 60 mm (width), and 65 mm (depth), which should be considered when planning the mounting space.

Advantages in Operation

The screwless connection technology reduces installation time and labor effort. The integrated strain relief protects the cable and extends the connection's service life. The IP44 protection rating provides sufficient protection against dust and splashing water, enabling use in various industrial environments. The clear red identification color supports safe assignment within the electrical system and prevents incorrect connections.
