Terminal Blocks - Barrier Blocks are an effective and efficient electrical interconnection mechanism. They provide a secure connection point between two electrical devices, such as a power supply circuit, controller, or sensor. They are also referred to as barrier blocks, plug-in terminals, wire-to-wire connectors, or polarity blocks.

A20710407R35 application field and working principle

The A20710407R35 is a barrier block which belongs to the above mentioned family of products. It’s particularly designed for high-power systems such as solar panel arrays, lighting, pumps, and other industrial automation applications. It can be used up to 35A, 900 V AC, with a rated voltage of 300V. It’s also UL Approved to UL 1059

A20710407R35 features a two-piece construction, designed to provide maximum flexibility and superior power or signal connections. Its two-piece construction is composed of two sets of modular components. The first is the base unit made of an orange reinforced thermoplastic base material. The second part is the top with a removable plastic gray cover. A20710407R35 offers a choice of screw, spring or mechanical locking connection types.

Apart from that, a major benefit of this model is the independency of power and signal sides of the voltage barrier. In this way the voltage barrier becomes a one-piece component, offering the best possible convenience and easy alignment. The base unit is designed to accept up to four wire sizes, either AWG 24-10 or metric 2.5-6. The top also accepts up to four wire sizes.

The working principle of this model is based on polarization. It includes an innovative system of three components: the ground connection, the disconnector blade, and the focus indicator which allows a safe and efficient connection in up to 32 ways. The ground connection is marked with a green indicator that is resistant to normal conditions. The disconnector blade operates mechanically and electrically.

The focus indicator is fitted to the connector and it enables polarization of the conductor that is being supplied. This polarization ensures that the power supply is directed to the right terminals and with the correct polarity. There is also a spring latch which helps to keep the connector from being removed accidentally.

The A20710407R35 is designed to meet the highest standards of safety and performance. It meets the most stringent requirements, providing exceptional performance over the long-term. Its compact design and resistant construction make it suitable for harsh industrial environments, while its integrated locking system guarantees reliable connections.

In conclusion, Terminal Blocks - Barrier Blocks are one of the most secure and reliable electrical interconnection mechanisms. A20710407R35 is a barrier block particularly designed for high-power systems, providing a safe and efficient connection in up to 32 ways. Its two-piece construction provides maximum flexibility and superior power or signal connections, while its integrated locking system guarantees reliable connections. It is UL Approved and meets the most stringent requirements.
