Tab/screw connector block 433-LA 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 with a only one screw, this

connector can be mounted twist-proof 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:

„L N [Earth]“
