Distribution block EBR2 4-11/125 R33RA-02020300301

EBR2 500 V distribution block designed for use in LV switchboards as an electrical power distribution element. It enables the safe separation of current paths at a rated insulation voltage of 500 V AC and high current carrying capacity.

Unlike standard EBR blocks, the EBR2 series features clearly separated wire inlets and outlets, which increases installation clarity, improves wiring organization, and raises the level of mounting safety.

The construction based on brass current paths ensures good conductivity and connection durability, while the polyamide housing and polycarbonate cover provide adequate insulation and user protection.

The transparent cover allows for optical inspection of the connection status without the need for disassembly. Additional polycarbonate partitions between the bars increase operational safety.

The block is adapted for mounting on a TSE 35 rail or directly to a surface (2 holes Ø5).

Screw terminals allow for the direct connection of cables and wires.
