DESCRIPTION

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]“

GENERAL INFORMATION

Pitch: 16.00 mm

No. of poles: 3

Additional information: These components cannot be mounted side-by-side. Multiple connectors can only be mounted side-by-side in 16 mm pitch to ensure clearance and creepage distances are observed.
