Teknomega PTB6030 single-pole 400A power terminal block with 1 input and 1 output for copper and aluminium conductors up to 185mm².
£24.44
The Teknomega PTB6030 is a heavy-duty single-pole power terminal block engineered for terminating and distributing high-current conductors in industrial switchboards, electrical distribution panels and automation cabinets. Also referenced as PTB 400, it features a 1 input / 1 output configuration with a 400A current rating, making it ideal for demanding industrial power distribution and feeder cable applications.
Manufactured using a durable PA6 UL94-V0 self-extinguishing insulating body with a tinned copper conductor block, the PTB6030 delivers excellent electrical conductivity, corrosion resistance and dependable long-term performance. Galvanised steel screws with aluminium clamps provide secure conductor retention, while the transparent protective cover helps prevent accidental contact and allows quick visual inspection of cable terminations.
Suitable for conductor sizes from 25 mm² to 185 mm² (stripped conductors) or 25 mm² to 150 mm² (conductors with ferrules), the PTB6030 offers a 1000V rated insulation voltage, 29.6kA short-time withstand current and 52.3kA peak withstand current, making it ideal for high-capacity industrial electrical installations.
The Teknomega PTB6030 is designed for terminating and distributing large conductors in high-current industrial electrical systems. Its robust construction provides secure, low-resistance electrical connections while simplifying installation and maintenance within modern switchboards and distribution equipment.
Ideal for OEM panel builders, electrical contractors and industrial engineers, the PTB6030 offers dependable performance in machine control systems, industrial automation, renewable energy installations and commercial power distribution applications.
