Why Choose the Teknomega PTB3612 Power Terminal Block?
The Teknomega PTB3612 is a heavy-duty 1-pole power terminal block designed for terminating large power conductors within industrial switchboards, distribution panels and control cabinets. Also referenced as PTB-1-300-B, it provides a 1 input / 1 output arrangement for direct high-current feeder connections.
Designed to accommodate both copper and aluminium conductors from 35–300 mm², the PTB3612 combines a tinned aluminium conductive block with galvanised steel clamping screws. Its insulating body and cover are manufactured from PA66 UL 94-V0 material, providing a robust self-extinguishing enclosure around the conductive components.
The PTB3612 has a rated insulation voltage of 1000 V AC / 1500 V DC, an impulse withstand voltage of 8 kV and an IP20 degree of protection. Its blue housing provides clear identification within electrical panels, while DIN rail and base-plate mounting options support flexible installation in demanding industrial power distribution systems.
