Teknomega PTB3611 single-pole power terminal block for aluminium and copper conductors from 35 mm² to 300 mm², designed for industrial electrical distribution.
£25.18
The Teknomega PTB3611 is a heavy-duty single-pole power terminal block designed for terminating large conductors in industrial switchboards, electrical distribution panels and automation cabinets. Also referenced as PTB-1-300-G, this grey terminal block supports both aluminium and copper conductors up to 300 mm², making it ideal for high-current feeder connections and demanding power distribution systems.
Manufactured with a durable PA66 UL94-V0 self-extinguishing insulating body and a tinned aluminium conductor block, the PTB3611 delivers excellent electrical conductivity and corrosion resistance. The pre-greased terminal chamber improves long-term connection reliability by helping to minimise oxidation when terminating aluminium conductors.
With a conductor capacity of 35 mm² to 300 mm², a rated insulation voltage of 1000 V AC / 1500 V DC and an 8 kV impulse withstand voltage, the PTB3611 is engineered to provide safe, dependable electrical distribution in demanding industrial environments.
The Teknomega PTB3611 provides a safe and dependable connection point for large power conductors used in industrial electrical systems. Its robust construction and high current capacity make it ideal for terminating feeder cables while maintaining low-resistance electrical connections.
Designed for switchboards, OEM equipment and automation panels, the PTB3611 combines durable materials with excellent electrical performance. Its compatibility with both aluminium and copper conductors makes it a versatile solution for modern industrial power distribution.
