£44.98
The Teknomega PTB3623 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-Y, this yellow-green terminal block features a 2 input / 2 output configuration, making it ideal for distributing large aluminium and copper conductors from a single connection point. It is particularly suited to protective earth and equipotential bonding applications where reliable high-current termination is essential.
Manufactured using a durable PA66 UL94-V0 self-extinguishing insulating body and a tinned aluminium conductor block, the PTB3623 provides excellent electrical conductivity while allowing direct connection of both aluminium and copper conductors. Pre-greased connection chambers help reduce oxidation and ensure dependable long-term performance in demanding industrial environments.
Supporting conductor sizes from 35 mm² to 300 mm², the PTB3623 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 PTB3623 provides a secure and organised method of distributing high-current conductors within industrial electrical panels. Its dual connection design enables feeder cables to be split efficiently while maintaining safe, low-resistance electrical connections that improve installation reliability.
Designed for switchboards, OEM machinery and automation systems, the PTB3623 combines durable construction with excellent electrical performance. Compatibility with both aluminium and copper conductors makes it an ideal solution for protective earth systems, industrial power distribution and modern electrical installations.
