990351

Weidmüller's 990351 establishes new benchmarks in Terminal Blocks - Adapters performance, specifically designed for renewable energy systems and smart grid applications. Its innovative design ensures decades of maintenance-free operation in outdoor installations.Accommodating Terminal Blocks, Screw Connection, 40 Pos, 2 Rows requirements, the adapter features UV-resistant housing and hermetically sealed contacts. This design prevents degradation from solar exposure and atmospheric contaminants.When converting to Rectangular Connector, Male Pins, 40 Pos, 2 Rows formats, the solution demonstrates superior performance in partial discharge tests. Its ceramic-filled polymer construction withstands 15kV dielectric strength.The DIN Rail options include specialized variants for photovoltaic installations. The DIN rail/channel version incorporates integrated surge protection for enhanced system reliability.Engineered for 14-26 AWG conductors, the adapter features dual-compression terminals that accommodate both solid and stranded wires without special tools. This design significantly reduces installation time in field deployments.
