Our 8NA junction boxes are part of the RCC-E K1 nuclear-grade product family 8NA, which is widely used in nuclear power plants around the world. With up to 14 different input and output combinations, these junction boxes can connect a wide range of safety-related devices and are ideal for cable optimization. They also have excellent shielding performance due to their low shell-to-shell resistance (≤ 20 mΩ) and their ability to achieve EMI/RFI protection over a wide frequency range. Our products are designed to withstand high radiation levels and harsh nuclear environments, and comply with LOCA safety requirements and major
