MCT-20

MCT-20 is a type of terminal block important for electrical connections and energy distribution. It is a barrier block solution mainly used for connection and disconnection, grounding, insulation and processing of power source in the electric control cabinet. It is commonly used in energy and control systems, motor control centers, and instrumentation applications.

MCT-20 is primarily composed of an aluminum barrier block, a constant-tension spring mechanism and a self-clinching screw with two flat insulation faces. The aluminum barrier block is made of conductive aluminum alloy and has an integrated contact and conductor protection feature. The constant-tension spring mechanism, which supports the contact during opening and closing of the connection, provides a maintaining a good connection when handling multiple connect/disconnect cycles. The self-clinching screw ensures a secure and reliable connection between contacts.

The working principle behind MCT-20 barrier blocks is based on the thermal conductivity of electrical materials. The aluminum barrier block acts as a heat sink, dissipating the heat generated by electrical current between two points of contact and allowing heat to transfer into the surrounding environment. This helps reduce contact resistance and improve device performance. When the contacts open and close, the contacts press, push and clamp the conductor lines in the aluminum barrier block into place. This ensures reliable electrical connections.

The main advantages of MCT-20 barrier blocks include a high current carrying capacity, low contact resistance, easy and fast installation, quick and secure connection to the contact and the conductor, and a long operational life. Additionally, the self-clinching screw connection system is flexible and secure, allowing the user to quickly disconnect or reconnect without additional tools or special skills. The constant tension spring mechanism also helps protect and maintain the contact, and avoids the tools from vibrating loose.

In general, MCT-20 is a reliable and dependable terminal block suitable for a variety of electrical and energy distribution applications. This simple and easy-to-use system provides a secure, reliable connection with a high current carrying capacity. The fast and easy installation process reduces the time and cost for wiring, while the environmental protection feature guarantees a long-term and secure solution for power supply connections.
