Phoenix Contact TB-EE-DB 175/2+10 DIN Rail Distribution Block 175 A 12-Way Screw Terminals

The Phoenix Contact TB-EE-DB 175/2+10 (Part No. 1725168) is a heavy-duty DIN rail-mount distribution block engineered for high-current power distribution and control panel wiring in industrial automation and machine-building applications. It features 12 screw-type terminals — a main line connection plus ten load pick-offs — enabling organized power splitting to multiple circuits from a single feed.

With a thermal continuous current rating of 175 A and a nominal voltage up to 1000 V AC (suitable for DC applications up to approximately 1500 V), this distribution block is ideal for main power feeds, busbar distribution, and high-current panels. Conductors are secured using robust screw connections, with ferrules recommended for flexible cable terminations.
