Teknomega PTB3622 heavy-duty single-pole 2 input / 2 output blue power terminal block for aluminium and copper conductors up to 300 mm², designed for industrial electrical distribution.
£44.98
The Teknomega PTB3622 is a heavy-duty single-pole power terminal block designed for high-current electrical distribution within industrial switchboards, automation cabinets and power distribution panels. Also referenced as PTB-2-300-B, this blue terminal block features a 2 input / 2 output configuration, making it ideal for branching and distributing large aluminium and copper conductors from a single connection point.
Manufactured using a durable PA66 UL94-V0 self-extinguishing insulating body and a tinned aluminium conductor block, the PTB3622 provides excellent conductivity and corrosion resistance. Pre-greased connection chambers help reduce oxidation when terminating aluminium conductors, ensuring reliable long-term performance in demanding industrial environments.
Supporting conductor sizes from 35 mm² to 300 mm², the PTB3622 is rated for 1000 V AC / 1500 V DC with an 8 kV impulse withstand voltage. Its robust construction allows installation on standard DIN rail or directly onto mounting panels, making it ideal for industrial power distribution systems.
The Teknomega PTB3622 provides a safe and organised method of distributing high-current conductors inside industrial electrical panels. Its dual connection design enables feeder cables to be split efficiently while maintaining secure, low-resistance electrical connections.
Designed for switchboards, machine control panels and OEM electrical equipment, the PTB3622 combines durable construction with high electrical performance. Compatibility with both aluminium and copper conductors makes it an ideal solution for modern industrial power distribution and neutral conductor installations.
