Power distribution blocks (PDB) for DIN rails
Weidmuller distribution blocks for wire cross-sections from 1.5 mm² to 185 mm² - Compact potential distribution blocks for the connection of aluminum wire and copper wire.
Phase distribution blocks (PDB) and sub-distribution blocks for potential distribution
Clamping blocks and power distribution blocks (PDB) for the DIN rail are suitable for collecting and distributing potentials within sub-distribution boxes and switchgear. The slim design of the power clamping blocks enables a clear and high wiring density. The power blocks are finger-safe on all sides in accordance with EN 50274 and the short-circuit resistance in accordance with the high SCCR standard (200 kA) also ensures a high level of safety.
Thanks to the special coating of the brass body, copper wire conductors, aluminum wires and flat conductors can be connected in the phase distribution block. Approvals according to VDE, UL, CSA and IEC enable use in further industrial applications and international markets.
Connection of copper and aluminum wires
The brass core of the distribution block with its special coating, in combination with the hexagonal screws, enables the connection of copper and aluminum wires. Both round and sector-shaped conductor designs can be connected in the power distribution block (PDB) on the DIN rail. The connection of flat conductors can also be realized in some potential distribution blocks.
Potential distribution blocks with each other bridges
The WPD potential distribution blocks (PDB) with screw connection can be cross-connected flexibly and easily via a flat copper bridge. A doubling or even tripling of the connection points on the outgoing side can thus be realized. For this purpose, the power terminal blocks can be latched together so that additional increased mechanical stability is achieved on the DIN rail.
Compact distribution block
The unique staircase design allows for a small size of the WPD potential distribution blocks (PDB). Compared to conventional setups, space savings are realized without loss of clarity within the cabinet.
For example, one wire with a rated cross-section of 95 mm² plus four wires with a rated cross-section of 95 mm² can be connected in a width of only 3.6 cm, with a minimum overall height of seven centimeters.
Color variations for every potential
Colored terminal blocks are available for clear wiring and installation of the switchgear cabinet. The color blue as N terminal block and green for a PE (ground) terminal block. Depending on the power distribution block and the application, the phase wiring can be selected between red, black, brown and grey.
