The Phoenix Contact UISLKG 16 is an installation protective earth terminal block designed specifically for the safe and reliable connection of protective earth conductors in electrical installations. The device serves as a terminal block for connecting protective earth conductors with a rated cross-section of up to 16 mm² and enables mounting on standard rail systems such as NS 35/7,5, NS 35/15 or NS 32. The terminal is equipped with a PE foot, which is secured to the rail using an M4 mounting screw, ensuring a stable and durable connection. The green-yellow color corresponds to the international marking for protective earth conductors and supports clear identification in system construction.

Applications

The UISLKG 16 is used in industrial and commercial electrical installations where safe earthing of devices and machines is required. It is particularly suitable for applications in automation technology, machine building, and electrical installation, where protective earth conductors are arranged in rows and connected via a common rail. The terminal is suitable for use in enclosures and distributions, where structured and clear cabling is necessary.

Functions and Equipment in Detail

The terminal features two connections implemented via a screw connection. This allows for a mechanically secure connection with cables in the cross-section range of 2.5 mm² to 25 mm². Mounting is achieved via a PE foot with an integrated M4 mounting screw, which is screwed into the mounting rail. The mounting method is designed for common standards NS 35/7,5, NS 35/15, and NS 32, enabling universal use in various enclosure environments. The green-yellow coloration is standard-compliant and serves to clearly identify the terminal as a protective earth terminal block.

Technology Explained Simply

The protective earth terminal block is designed to ensure a stable electrical connection between the protective earth conductor and the earthing bar. The screw connection provides a secure contact that remains intact even under mechanical stress and vibrations during operation. The M4 mounting screw allows for precise and durable installation on the rail. The terminal is rated for a cross-section of 16 mm², meaning it is designed for cables with a maximum cross-section of 16 mm², while also accommodating smaller cross-sections from 2.5 mm² to 25 mm². The green-yellow color is specified by international standards for protective earth conductors and supports compliance with safety standards.

Compatibility and Accessories

The terminal is compatible with common mounting rails NS 35/7,5, NS 35/15, and NS 32, which are widely used in industrial electrical installations. It can be arranged in rows to realize multiple protective earth connections on a single rail. The terminal is used in conjunction with protective earth conductors in the cross-section range of 2.5 mm² to 25 mm².

Mounting and Installation

Mounting is performed by screwing the M4 mounting screw into the designated mounting rail. The terminal is inserted into the rail and secured with the screw. The connections are made via the screw connection to the protective earth conductors. Installation is simple and requires no special tools other than a screwdriver or an appropriate key for the M4 screw. The terminal is designed for use in enclosures and distributions, where structured and clear cabling is necessary.

Advantages in Operation

The UISLKG 16 provides a reliable and secure connection for protective earth conductors, which is crucial for electrical safety in installations. The use of a screw connection and PE foot ensures a mechanically stable and electrically conductive connection. Compatibility with common mounting rails enables flexible integration into existing systems. The green-yellow coloration supports compliance with safety standards and facilitates maintenance and inspection of the installation.
