JCST Surge protection devices are designed to absorb and dissipate the excess electrical energy caused by power surges, ensuring that the equipment connected to the system is not damaged. JCST SPDs can help prevent costly equipment downtime, repairs, and replacements.
JCST surge arrestors are designed to absorb and dissipate the excess electrical energy caused by power surges, ensuring that the equipment connected to the system is not damaged. This SPDs can help prevent costly equipment downtime, repairs, and replacements. The devices are also designed to be easy to install and maintain.
JCST Spds is characterized by its capacity to safely discharge current with 8/20 µs wave form. T2 and T2+3 SPDs are available in specific multi-pole versions for all distribution systems.
Our JCST surge protection device is built with the latest technology and a sleek, modern design that will blend seamlessly with any electrical system. It is DIN-rail mountable, making it easy to install and use in a variety of settings.
One of the most critical features of our surge protection device is its nominal discharge current In 30kA (8/20 µs) per path. This means that it can withstand high levels of electrical surges without causing any harm to your equipment. Furthermore, its maximum discharge current Imax 60kA (8/20 µs) makes it a powerful tool in preventing damage caused by surges.
Our JCST Surge protection device is ergonomically designed to ensure maximum protection for all of your electronics. It is crafted from high-quality materials and carefully tested to ensure that it can withstand any power surge.
