Why Choose the Cembre 2843709 DB400-11/1N Single Pole Distribution Block?
The Cembre 2843709 DB400-11/1N is a heavy-duty single-pole power distribution block engineered for high-current industrial power distribution. As part of the professional Cembre DBLOCK series, it provides a secure and organised method of distributing a single incoming supply to multiple outgoing circuits within control panels, switchboards and power distribution systems.
With a 400 A operating current, the DB400-11/1N features one high-capacity incoming connection and 11 outgoing terminals. Direct-clamping terminals, captive screws and chamfered conductor entry holes simplify installation while maintaining secure, low-resistance electrical connections for demanding industrial applications.
The conductor body is manufactured from electrolytically tin-plated brass for outstanding conductivity and corrosion resistance. A robust halogen-free Polyamide PA6.6 body with a transparent polycarbonate cover provides excellent insulation, quick visual inspection and IP20 protection. The block can be mounted directly onto a standard 35 mm DIN rail or fixed to a panel where required.
