Tab/screw connector block 433-ZA is available in 3-pole design. It is equipped with

a one-piece metal part on mains and equipment side avoiding contact resistance

inside the connector.

Thanks to mounting holes between the poles and a protecting peg, this connector

can be mounted twist-proof with a only one screw on an appropriately prepared

substrate.

The wire protector of the “DS”-version reliably prevents damage to multi-wire

flexible conductors by the turning screw.

This type features the additional permanent marking:

„R S N“
