Thomas and Betts offer power distribution blocks with insulated housing and factory-controlled dielectric strength

Thomas & Betts' Blackburn® Power Distribution Blocks, which include terminal and tapping blocks, offer insulated housing and factory-controlled dielectric strength for quick, clean and safe termination of aluminum and copper conductors.  Power Distribution Blocks also feature position-locked DIN rail mounting or screw mounting to the back plate, offering flexibility in installation.  Additional features include halogen-free polyamide body construction for IEC 529-compliant, IP-20 grade finger-safe protection.

Terminal blocks are available in both single and three-pole applications, and include both traditional and tapping terminal blocks in a modular system that enables the addition and combination of poles to meet a variety of requirements.  Traditional three-pole terminal blocks also are available for three-phase systems.  Tapping blocks offer one pole with four identical terminals. 

Blackburn® Power Distribution Blocks' aluminum contact surfaces are tin plated for corrosion resistance, and are grooved for better penetration of conductor oxides.  Terminals are pre-lubricated with an anti-oxidation compound that offers the best corrosion resistance.    

“Blackburn® Power Distribution Blocks are versatile in their applications,” said Senior Product Manager Jerry Woodward of Thomas & Betts' Industrial Products Group, “which range from low-voltage switchgear and control gears for industry and construction to building automation.  They're ideal for distribution panels, control boxes, automation devices and ESS centers in OEM and retrofit operations.”

Blackburn® Power Distribution Blocks have a maximum voltage of 600V, maximum temperature of 80 C (276 F) and a flammability rating of V-2 (UL94).  They also are compliant with UL 1059, Category XCFR2, File Number E66436.
