The compact and innovative connectors ensure high current carrying capacity, a pull-resistant connection and a very stable fixing to the DIN rail.
PRKD and PSLD connectors are 2-layer connectors for a nominal wire size of 2.5mm². The PRKD connectors are either at different potentials or at one potential, the black colour at the top of the connector visually distinguishes the connector at one potential. Visual attention is also available for N and PE terminals, where the area surrounding the terminal is coloured blue or yellow-green respectively.
PSLD connectors are always at the same potential and coloured yellow-green, these can be grounded to the DIN rail. Also the PRKD connector, where the lower level is a protective earth, is grounded to the rail according to the standards.
