DistributionSystem GPolybloc distribution blockCatalogue numbersDD381399GeneralDownstream circuits are connected from the front, without screws, to springterminals. Contact pressure automatically adapts to the size of the conductor(minimum size = 1 mm 2 ). Contacts are insensitive to vibrations and thermalvariations.Only one cable (flexible or rigid, without a metal ferrule) can be inserted in a springterminal.Degree of protection: IPxxB.Advantages of spring terminalsb a reliable electrical connection, no maintenance requiredb the fast connections make phase balancing very easy.b rewiring is very easy if the switchboard is expanded or modified.PD390549250 A Polybloc distribution block ApplicationsThe Polybloc distribution block is designed for installation directly downstream ofCompact circuit breakers and Interpact switch-disconnectors devices up to 250 A.It can be rapidly mounted in the horizontal position. Electrical connections are madedirectly to the device terminals.It has the same width as the devices and does not take up any additional space inthe switchboard.The connection terminals are slanted to facilitate cable entry and not exceed thebending radius of the flexible and rigid cables.Cat. no. selectionDesignationCat. no.Polybloc distribution block, 3P, 250 A 04033Polybloc distribution block, 4P, 250 A 04034DD380587Horizontally mounted Polybloc in a wall-mount enclosure.Electrical characteristicsThe electrical characteristics are perfectly compatible with the connected devices.Neither the temperature derating curves nor the performance levels of the circuitbreakers and switch-disconnectors are altered.b rated insulation level Ui = 750 Vb short-circuit withstand current: the reinforced breaking capacity due to cascadingin circuit-breaker combinations is maintained. The worst-case situations have beentested.impulse withstand voltage Uimp = 8 kV.SupplyDirectly to the terminals of the Compact NS and Interpact INS devices up to 250 A.DistributionVia cables, up to six 10 mm² cables and three 16 mm² cables per phase.InstallationDirectly on the mounting plates of horizontally mounted Compact NS100/250 andInterpact INS250 devices in the enclosures.It can also be mounted downstream of vertically mounted Compact NS100/250 andInterpact INS250 devices in the enclosures. In this case, the Polybloc is mounted ona depth-adjustable modular rail (03002 System G) or (03402 System P).DimensionsH (mm) L (mm) P (mm)Polybloc, 3P 105 138 63Polybloc, 4P 140 138 63DD381406110
