DEHN placa de contacto M8 com furo quadrado 540251

Busbar connections often require a reliable, low-resistance tap-off point that can accommodate square-head bolts without slipping. The DEHN 540251 contact plate solves this by providing a tinned electrolytic copper plate with an M8 threaded connection and a 9 x 9 mm square mounting hole, ensuring a secure fit for square-head bolts such as DIN 603.

Who is it for

Electricians and panel builders who need to create robust electrical connections on busbars or equipotential bonding bars. This plate is suitable for use with M8 bolts and square-head bolts, offering a dependable tap-off point in low-voltage installations.
