£25.18
The Teknomega PTB3613 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-Y, this yellow-green terminal block supports both aluminium and copper conductors up to 300 mm², making it ideal for high-current feeder connections, protective earth installations and demanding industrial power distribution applications.
Manufactured with a durable PA66 UL94-V0 self-extinguishing insulating body and a tinned aluminium conductor block, the PTB3613 provides excellent electrical conductivity while allowing direct connection of aluminium and copper conductors. The pre-greased terminal chamber helps reduce oxidation, ensuring dependable long-term electrical performance in harsh industrial environments.
Supporting conductor sizes from 35 mm² to 300 mm², the PTB3613 is rated for 1000 V AC / 1500 V DC with an 8 kV impulse withstand voltage. Its robust construction and compact design allow installation on DIN rail or directly onto mounting panels within electrical enclosures, making it suitable for modern industrial and commercial electrical systems.
The Teknomega PTB3613 provides a secure connection point for large power conductors used in industrial electrical systems. Its robust construction and high current capacity make it suitable for terminating feeder cables while maintaining low-resistance electrical connections in demanding industrial applications.
Designed for switchboards, OEM equipment and automation panels, the PTB3613 combines durable construction with dependable electrical performance. Compatibility with both aluminium and copper conductors makes it an excellent solution for protective earth connections, industrial distribution boards and modern electrical installations.
