UKJ series screw frame clamp terminal blocks fulfill allrequirements of IEC60947-7-1、IEC60947-7-2、GB14048.7 GB/T14048.8 and JB/T9659.1 etc. Standards. This series terminal blocks can be used  in the circuit thatAC50Hz(60Hz), rated voltage is 500V-1000V, to connect

round copper conductor which unprocessed or with terminal sand which rated cross section is 0.14mm2~240mm2.UKJ series terminal blocks have CE Approval in 2001,CCS (China Classification Society) Approval on January 2002,and CQC (Quality System Certificate), leading modelsproducts have VDE and UL Approval in 2005..

Characters

1、 Reasonable structure, mounting on G or TH rails expediently with its  reasonable structure and flexible Nylon material, universal, install with bracket when cross section larger than 50mm2;

2、Compact, more model for your need, can connect with large cross section wire;

3、Good conductivity, copper clamp frame and copper screw are used when  cross section less than 50mm2, and steel clamp frame and steel screw are used when larger than 50mm2 to ensure large torque.
