PTB3522 Teknomega 1 Pole 2 Way Connectors Power Terminals

Why Choose the Teknomega PTB3522 Power Terminal Block?

The Teknomega PTB3522 is a heavy-duty single-pole power terminal block designed for high-capacity power distribution within industrial switchboards, automation cabinets and electrical distribution panels. It features a 2 input / 2 output configuration supporting aluminium or copper conductors from 35 mm² up to 240 mm², allowing efficient feeder branching from a single supply connection.

The terminal block is manufactured using a robust PA66 UL94-V0 self-extinguishing insulating body combined with a tinned aluminium conductive block and galvanised steel clamping screws. This construction ensures strong electrical conductivity and reliable cable retention when connecting both copper and aluminium conductors. The unit is rated for 1000 V AC / 1500 V DC with an impulse withstand voltage of 8 kV, providing dependable performance in demanding industrial installations.
