Tab/screw connector block 433-ZB 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:
„L N [Earth]“
