PTB3621 Teknomega 1 Pole 2 Way Connectors Power Terminals

Why Choose the Teknomega PTB3621 Power Terminal Block?

The Teknomega PTB3621 is a heavy-duty single-pole power terminal block with dual connections designed for high-current electrical distribution in industrial switchboards, electrical panels and automation cabinets. It provides a 2 input / 2 output configuration, allowing efficient connection and distribution of large feeder cables while maintaining a compact installation footprint.

Engineered to support aluminium or copper conductors from approximately 35 mm² up to 300 mm², the PTB3621 is suitable for high-capacity industrial power systems. The terminal features a PA66 UL94-V0 self-extinguishing insulating body, a tinned aluminium conductive block, and galvanised steel screws to provide reliable conductivity and corrosion resistance when connecting mixed conductor materials.

With a rated insulation voltage of 1000 V AC / 1500 V DC, impulse withstand voltage of 8 kV, and a typical current rating of around 440 A, the PTB3621 delivers dependable performance in demanding industrial power distribution environments.
