Terminal Blocks are complete units for switching, distributing, measuring and controlling electrical energy, signals and data. As the backbone of an electrical panel, they significantly simplify the wiring design, reduce labor costs, save time and effort, and create greater flexibility for easy panel remodeling. The Din Rail, Channel type of terminal blocks have been designed for front panel mounting, to provide the highest degree of flexibility to the electrical wiring designer. They are manufactured with threaded, tapped metal mounting brackets that allow for quick installation onto "Din Rail" which is often included in most electrical control systems. Despite their compact size, these terminals are very user friendly and are designed to provide the highest level of performance in a variety of circuits.

The Din Rail, Channel terminal blocks have been designed to accommodate the 3244628 application field. These terminals are constructed of molded plastic insulator blocks containing integral clamping screws with the threads molded in place. This integral thread design eliminates the thread stripping that commonly happens with plastic threaded models. The conducting portions of the terminal block are made of galvanized pre-treated metal, designed to provide the best possible conductivity and contact resistance. The screw heads are color coded to allow easy identification of the 1.5mm² to 2.5mm² conductor size range.

The 3244628 terminal block’s working principle is to clamp the conductor and provide a mechanical and electrical connection between the conductor and the connection point. When a conductor enters the terminal block, the conductor is clamped and held in place by the clamping screw via the pressure spring. The clamping force is a predetermined value and is held constant. This ensures that optimal contact pressure is maintained on the conductor being used. The contact surface pressure remains constant regardless of the temperature. This prevents cold-weld oxidation and allows for superior current carrying capabilities over extended periods of time.

The terminal blocks also have the capability to be insulated from one another and from the mounting surface. This can be accomplished using either a variety of mounting accessories, such as mounting plates, nuts and screws, or using stacked head separators. The terminals themselves can also be easily isolated by sliding movement to reduce the maximum current load. This feature allows the user to safely add to an existing circuit or reroute currents on the fly.

The 3244628 application field and working principle of the Din Rail, Channel type of terminal block makes it an ideal choice for many different electrical wiring needs. The terminals are suitable for both high and low voltage, allowing for both power and control wiring scenarios. The compact design and color coded screw heads also make these terminal blocks easy to use and cost effective. The pressure spring ensures an optimal contact pressure for maximum current carrying capabilities, while the isolated design allows for both reroute current and adding an additional circuit to an existing one. All of these features make the Din Rail, Channel terminal block a perfect choice for any project that requires a secure, reliable and cost efficient connection solution.
