Phoenix Contact TB-EE-DB 250/1+11 DIN Rail Distribution Block 250 A 12-Way Screw Terminals

The Phoenix Contact TB-EE-DB 250/1+11 (Part No. 1725169) is a heavy-duty DIN-rail-mount distribution block designed for high-current power distribution and organized wiring in industrial panels, machine control cabinets, and electrical service boards. It supports a nominal voltage up to 1000 V AC and a thermal continuous current rating of 250 A, making it ideal for robust power-feed applications.

This distribution block features 12 screw-type terminals (one main feed and 11 load connections) with a rated cross section of 95 mm², accommodating a wide range of conductor sizes. The line contact accepts conductors from 35 mm² to 120 mm² and the load contacts from 2.5 mm² to 35 mm², enabling flexible multi-circuit connections with secure screw clamping. The block mounts easily to NS 35/7.5 or NS 35/15 DIN rails or can be directly panel-mounted for compact installations.

Built in a rugged dark gray housing with dependable electrical performance and clear load separation, this distribution block is perfect for power splitting, multi-circuit distribution, and professional-grade panel wiring in demanding industrial environments.
