Why Choose the Cembre 2843703 DB125-7/1N Single Pole Distribution Block?
The Cembre 2843703 DB125-7/1N is a premium single-pole power distribution block designed to provide safe, organised and reliable electrical power distribution within industrial control panels, switchboards and automation systems. As part of the proven Cembre DBLOCK series, it enables a single incoming supply to be distributed efficiently to multiple outgoing circuits while maintaining secure electrical connections.
Rated at 125 A, the DB125-7/1N features one incoming connection and seven outgoing terminals, making it ideal for simplifying panel wiring and reducing installation time. The conductor body is manufactured from electrolytically tin-plated brass to provide excellent conductivity and corrosion resistance, while the robust halogen-free Polyamide 6.6 housing delivers long-term mechanical strength and electrical insulation.
Designed for installation on a standard 35 mm DIN rail, the distribution block also includes captive screws and chamfered conductor entry holes to simplify wiring. Its transparent cover allows quick visual inspection while maintaining IP20 protection, making it suitable for demanding industrial environments.
