Why Choose the Teknomega PTB3323 Power Terminal Block?
The Teknomega PTB3323 is a high-current 1-pole power terminal block with four conductor connections, arranged as 2 inputs / 2 outputs. Also referenced as PTB-2-95-Y, it is designed for secure power distribution and conductor termination within industrial switchboards, control panels and electrical distribution enclosures.
The PTB3323 accepts both copper and aluminium conductors from 16–95 mm², providing flexibility for industrial power distribution applications. Its yellow/green insulating housing is manufactured from PA66 UL 94-V0, while the conductive block is tinned aluminium and the clamping screws are galvanised steel for dependable electrical and mechanical connections.
With a rated insulation voltage of 1000 V AC / 1500 V DC, an impulse withstand voltage of 8 kV and IP20 protection, the PTB3323 is engineered for demanding panel-building applications. It is rated for a conventional free-air thermal current of 245 A with copper conductors and 220 A with aluminium conductors.
