302-NSTB (-DS)

Plug-In Terminal Strip

Screw connection & socket, low profile version

https://wecoconnectors.com/wp-content/uploads/Images/302-NSTB-R.JPG

DESCRIPTION

The plug-in terminal strip 302-NSTB, lower version, is available in 8 mm pitch with 2 to 12 poles. It has one screw connection per pole and one plug connection for a terminal strip with pins. The slotted pins and slotted sockets of 302-NSTS plug-in terminal strip create appropriate contact pressure. Due to the small 8 mm pitch, this version is well suited for applications where space is limited. The “N”-variant only differs from the standard 302-STB version by the 12 mm overall height (i.e. the moulding height is 3 mm lower). Note the shortened clearance and creepage distances. The wire protector of the “DS”-version reliably prevents damage to multi-wire flexible conductors by the turning screw. These terminals strips can be screw-mounted on a substrate.
