Stainless steel junction box A-SXL

ceramic4 knockouts

Hermetically sealed Junction Boxes are robust stainless steel enclosures designed for use inside reactor buildings, where it is necessary to connect or extend cables from sensors, safety equipment, and other instrumentation devices to reach the containment penetration or control room. These boxes are engineered for demanding environments and feature up to four cable inlets, allowing two cables to be connected. Inside, temperature- and radiation-resistant ceramic terminal blocks ensure reliable operation. The construction is entirely inorganic, providing excellent resistance to radiation and high temperatures, with continuous operation possible at temperatures up to 180 °C. The junction boxes can be qualified up to K1 classification. Cable entry is achieved using eddylab’s patented hermetically sealed connectors, with the option for customer-specific solutions or cable glands upon request.
