The OSTTR221551 is one of the most popular and versatile products in the terminal block category of wire to board. This terminal block is made of high grade steel, with a plated zinc-nickel finish for increased corrosion resistance and improved mechanical durability. Its outer plastic housing offers excellent insulation protection while avoiding oxidation.

The OSTTR221551 terminal block is designed for use in industrial and control installations. It is a current-carrying device that provides a secure, stable and control connection for 1 to 4 conductors. It is designed for mounting on terminal strips, railings, equipment, switchboards or DIN rail.

The application field of OSTTR221551 is for applications that require higher short-circuit currents, astronger operation, good resistance to vibration and temperature changes, and compatibility withvarious sizes and shapes of cables.

The working principle of OSTTR221551 is that it works with two clamps, the lower and the upper clamp. The upper clamp is connected to the fixed bridge, which is kept in place by the screw. The lower clamp is activated by insertion of the conductor into the terminal block cavity, and is fastened into place when the screw is screwed down.

This terminal block is capable of carrying and controlling much higher current thanstandard terminal blocks. It offers various advantages, including simple and quick installation,strong contact pressure, secure clamping and protection against vibration, and is suitable forcontinuous high-temperature applications. It also has excellent low-resistance connection, and isable to increase power transmission.

The OSTTR221551 terminal block is available in various sizes and shapes, and is suitable for systems with different conductor diameters. With its higher capacity for current transmission, low contacting resistance and mechanical properties, it is the preferred option for applications with constant power transmission and reliable current control. It is the ideal choice for both domestic and industrial usage, where resilience and reliability are key.
