Teknomega PTB3313 heavy-duty single-pole yellow-green power terminal block for aluminium and copper conductors from 16 to 95 mm² with a 245 A copper current rating for industrial electrical distribution.
£6.71
The Teknomega PTB3313 is a heavy-duty single-pole power terminal block designed for the safe termination of large aluminium and copper conductors within industrial switchboards, electrical distribution boards and automation control panels. As part of the robust Teknomega PTB power terminal block range, it provides reliable, high-current electrical connections while maintaining a compact installation footprint.
Manufactured with a durable PA66 UL94-V0 self-extinguishing insulating body, a tinned aluminium conductor block and galvanised steel clamping screws, the PTB3313 delivers excellent conductivity, corrosion resistance and long-term mechanical reliability. The conductor block is supplied pre-greased, improving conductor contact and simplifying installation of both aluminium and copper cables.
Supporting conductor sizes from 16 to 95 mm², the PTB3313 offers a continuous thermal current rating of 245 A (Cu) and 220 A (Al). Its yellow-green housing makes it ideal for protective earth conductor identification, while its versatile design supports installation on a 35 mm DIN rail or directly onto a panel.
The Teknomega PTB3313 is designed for terminating large protective earth conductors used within industrial electrical distribution systems. Its heavy-duty construction delivers dependable electrical continuity while maintaining a compact footprint inside switchboards and electrical panels.
Compatible with both aluminium and copper conductors, the PTB3313 reduces inventory requirements by supporting multiple cable types within a single installation. Its tinned aluminium conductor block and pre-greased connection points help deliver long-term electrical reliability in demanding industrial environments.
