O—————_O| |Short Description|Multi level terminal block - Screw Connection| |Full Description|Terminal Type - KU2D4 , Multi level terminal block, nominal voltage:
500 V, nominal current: 24 A, connection method: Screw connection,
number of connections: 4, cross section: 0.5 mm² - 4 mm², AWG: 20 -
12 , width: 6 mm , length: 50 mm , height : 50.8 mm , mounting
type: NS 35/7.5, NS 35/15 , NS 32/15| |Approvals|~~CE~~OOOOUA| |Standard Colour|Gray| |Colour Variants|Black , Blue , Green , Khakhi , Red , Yellow ,| |Your Advantages|Since there are two function shafts per level, all potential distribution
tasks can be implemented quickly . Two separate potentials can by
routed side by side with the help of bridging between non-adjacent
terminal blocks .| ## **Key Commercial Data** |Standard Weight|1.25 Kg| |---|---| |Weight per Piece (excluding packing)|11.4 g| |Packing Unit|100 pc| |Minimum Order Quantity|100 pc| |GTIN Number|85389000| |Country Of Origin|INDIA| _**1**_ |Number of levels|2| |---|---| |Number of connections|4| |Potentials|2| |Nominal cross section|2.5 mm
