www.usa.siemens.com/terminalblocks New product announcement Distribution blocks We are pleased to announce that Distribution Blocks are now released for sale. Distribution blocks are used to realize single-, two-, threeand four-phase systems up to a rated current of 400 A. This enables to split power supply circuits in several load circuits with different cable cross-sections. The following Distribution Blocks are SCCR rated only with Class J Fuses. See detailed technical sheet on the next page. High thermic and mechanical robustness Distribution blocks are made of thermoplastic with electrical and mechanical parts, which allows a usage under high thermic and mechanical load according to IEC 60947-7-1. Highlights n Fast mounting on DIN-Rail with click connection or on mounting plate with 2 x M5 screws n Place saving n Safety because of IP20 degree of protection and no cap to open or remove Catalog number No. of poles Ampere rating 5ST2504 1 80 600V 5ST2505 1 125 600V 5ST2507 1 160 600V 5ST2508 1 250 600V 5ST2511 1 350 600V Voltage Answers for infrastructure and cities.
