Weidmüller AITB 4 BB N-L-PE Installation Terminal Block 2669090000

The Weidmüller AITB 4 BB N-L-PE is a high-quality installation terminal block designed for reliable and safe electrical connections in industrial and building installations. This terminal block integrates three potentials (N, L, PE) with a total of 12 connection points, making it ideal for distributing power and signals in control cabinets and junction boxes.

Advantages

Robust screw connection technology ensures secure and durable wiring. The Wemid (PA 66) insulating material provides excellent thermal and mechanical resistance, while the compact design saves space on DIN rails. Rated for voltages up to 400 V and currents up to 32 A, it meets the demands of modern electrical systems.
