Terminal Blocks - Interface Modules are a versatile and efficient form of modern electric connection systems, providing a safe and reliable link between two points, and a guarantee of secure electrical connection for a variety of applications.

A terminal block is a type of connection solution, typically consisting of two electrical terminals which are connected by an insulated barrier. It is common practice to use a variety of terminal blocks for various types of electric devices, ranging from lighting and home appliances to industrial equipment. Terminal blocks are available in a variety of sizes, shapes, and types for a multitude of applications.

The 2905300 series is a product range from Phoenix Contact, a leading supplier of electrical components and systems. The series includes both signal and power terminal blocks, each designed to withstand high currents and voltage systems.

The signal and power series available within the 2905300 series are used for a variety of electrical connections including connection and conversion of conductors, grounding, and overvoltage protection. This is often combined with additional devices such as plug-in bridge, interlocking systems, and protective circuit breakers. The signal and power terminal blocks are equipped with various terminals, and a variety of contact elements to ensure maximum environmental compatibility even in harsh or aggressive conditions.

The following explains the different types of 2905300 series terminal blocks and their application field and working principle.

Power Terminal Blocks:

The power terminal blocks in the 2905300 series include the MMC2, MCS, and MCL series. These terminal blocks offer a flexible connection for high current and voltage applications. They are available with rated currents of up to 63 A and 400 V and are made from robust thermoplastic material.

The power terminal blocks have a double row of technology slots, allowing two bridge systems to be interconnected, which helps connect conductors in situations for which a single block may not be suitable. They also feature a recessed screw head that ensures a safe and secure connection by avoiding loose strands, additionally the stable and robust housing of the blocks ensures reliable and secure connection.

Signal Terminal Blocks:

The signal terminal blocks in the 2905300 series include the Quicksys series which is the standard modular system from Phoenix Contact. It is made from impact-resistant and self-extinguishing insulation material and is available with rated currents of 8 A and 24 V.

The signal terminal blocks are designed to allow a variety of signal inputs, including high-voltage or low-voltage inputs, including differential signals. These blocks are also suitable for use in intrinsically safe environments, as they are designed with a grounding loop that allows for overvoltage protection.

Additionally, an optional integrated fuse holder can be used as a safety feature to protect against over current.

Work Principle:

The work principle of the 2905300 series terminal blocks is fairly simple, with the bridging of two terminals. When an electrical circuit is created, electrons flow from one terminal to the other, thus providing the electric connection. This is a safe and reliable form of connection, as the insulated barrier between the terminals prevents any short circuits or arcing which may occur during the flow of electricity.

The signal and power terminal blocks in the 2905300 series are designed with a variety of features in order to ensure maximum safety and reliability in any environment. Features such as insulated barriers, stable and robust housings, integrated fuse holders and recessed screw heads ensure that the electric connections are made safely and securely.

The 2905300 series terminal blocks are a versatile and efficient form of electric connection systems, providing a safe and reliable link between two points, and a guarantee of secure electrical connection for a variety of applications.
