The Phoenix Contact MPT 1,5/S is a mini passage terminal block designed for use in industrial electrical installations. It enables secure and quick connection of cables with a rated cross-section of 1.5 mm² and is intended for mounting in NS 15 plug-in rails. The terminal block features a push-in connection, allowing simple and tool-free cable connection, thereby reducing installation time. The grey colouring is typical for the series and supports visual identification in the enclosure.

Applications

The MPT 1,5/S is suitable for applications in industrial electrotechnics, particularly in enclosures and control systems, where compact and reliable connection technology is required. Due to its rated voltage of 500 V and rated current of 17.5 A, it is suitable for medium to high electrical loads. The terminal block is designed for use in the first tier, meaning it can be mounted in a row with other terminals to realise multiple connections in a compact area.

Functions and Equipment in Detail

The terminal block features two connections, each designed for a conductor cross-section of 0.14 mm² to 1.5 mm². The push-in connection allows cable insertion without tools, with the connection secured by an integrated spring mechanism. This reduces the risk of loosening and improves connection reliability. The terminal block is intended for mounting in NS 15 plug-in rails, ensuring standardisation in enclosure technology.

Technology Explained Simply

The push-in connection is a modern connection technology where the cable is simply inserted into an opening and automatically secured by spring pressure. This eliminates the need for screwdrivers or other tools, speeding up installation and reducing error susceptibility. The rated voltage of 500 V and rated current of 17.5 A define the maximum electrical loads the terminal block can safely transmit. The rating for a cross-section of 1.5 mm² corresponds to typical use in control and drive technology.

Compatibility and Accessories

The MPT 1,5/S can be combined with various accessories to extend functionality. These include plug bridges in different pole counts (e.g. 2-, 3-, 4-, 5-, 10- and 20-pole), enabling parallel connection of multiple terminals. Test plugs such as PS-3,5/E or PS-3,5 are used for diagnosis and testing of connections. Insulating sleeves in various colours (red, black) can be used to mark conductors. Additionally, screwdrivers and marking bands are available to assist with installation or marking. Terminal block markers (UCT-TMF 3,5) allow individual labelling.

Installation and Mounting

Mounting is done in NS 15 plug-in rails, commonly found in standard enclosures. The terminal block is simply inserted into the rail and securely held by a spring locking mechanism. Cable connections are made tool-free by inserting into the push-in connection. During installation, ensure the conductor cross-section is within the permissible range of 0.14 mm² to 1.5 mm² to guarantee a secure connection.

Operational Advantages

The MPT 1,5/S offers fast and reliable connection technology, reducing installation time in the enclosure. The tool-free connection via the push-in connection reduces the risk of installation errors. The high rated voltage and current make the terminal block suitable for a wide range of industrial applications. Compatibility with various accessories expands usage possibilities and supports maintenance and diagnostics.
