433-LA (-DS)
Tab/Screw Terminal Block
Tab 6.3 mm, with marking "R S N"
DESCRIPTION
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: „R S N“
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.
