Distribution block EBR 4-11/125 R33RA-02020200201

EBR 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.

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 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.
