Barrier blocks are used in areas where it is necessary to keep wires or devices in groups or to prevent the mixing of different circuits or voltages. Within the broad category of terminal blocks, barrier blocks are designed to prevent the possibility of short-circuit, contamination, or interference between wires or circuits. In environments where safety is reasonably a major concern, such as those where electrical, chemical, and thermal hazards are present, suitable barrier blocks are a necessity. Depending on the application, the blocks provide the needed protection and also allow for easy removal, inspection, or replacement of wires, while also preventing the establishment of hazardous sparks.

The NDN1A-WH series barrier block is a two-tier, 20 pole block designed in a “S” shape. It is equipped with “snap on” lugs and is made of self-extinguishing thermoplastic material. It provides four electrical isolating barriers and is available in three male/female and four male/male options, each with three lead-free/tin-plated terminals to fit a variety of wire sizes. NDN1A-WH is rated for 600 Volts with a capacity of 12 Amps, and UL components with RoHS/WEEE and CE certification.

The NDN1A-WH barrier block is ideally suited for a wide range of applications, from industrial systems to consumer devices. It is commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems, providing a secure connection between resistors, contactors, and pressure sensors. The NDN1A-WH can also be used in electric vehicle charging stations, providing the necessary voltage and current levels to the vehicle battery.

An important factor to consider when using barrier blocks is their working principle. The NDN1A-WH series is designed with an insulating partition between the two rows of terminals, which provides electrical isolation between them. This partition ensures that the voltage is evenly distributed throughout the block and prevents any possible short circuits. In addition, the lugs on the terminals provide an additional protection to ensure that wires do not accidentally become disconnected or pulled out of the block.

The NDN1A-WH series barrier block is a reliable and economical alternative for dangerous wiring in areas with high safety standards. Its “snap on” lugs provide protection against accidental disconnection and its insulating partition prevents short circuits and contamination due to electrical interference. Its 600V rating, UL components, and RoHS/WEEE and CE certification make it adaptable for a wide range of applications in various industries.
