Heyco Products, Inc., an industry leader in the design and manufacture of precision-molded wire-protection products and stamped metal electrical components, introduces ERTB Terminal Blocks for all high current draw and aluminum wire applications.

Product Applications
Small footprint, three-pole ERTB Terminal Blocks provide secure, reliable points of connection and transmission for incoming power line service to electrical equipment of many kinds. ERTB is especially suited for high-capacity standard copper listed or new UL-aluminum wire connections in consumer or commercial appliances, such as electric ranges, washers and dryers, electric water heaters, heat pumps, power generators, HVAC equipment, machinery, and other applications that require copper or aluminum wire hookups.


Product Description
ERTB Terminal Blocks are compact, sturdy, post-to-clamp style unitized blocks that mount to any cabinet or housing attachment point. Each of these electrical poles has a protective strip under each tightening screw that does not pierce either copper-wire strands or softer aluminum wire, holding both equally tight. Where aluminum wire is used, it needs minimal torque at installation, to remain secure without working loose from current-induced expansion and contraction.
Each low-profile terminal block has a single-row, three-wire pole design that accommodates line voltage on one or two poles, handling neutral and ground wires on the one or two remaining poles. Poles accept 6-4 AWG aluminum wire, or 10-6 AWG copper stranded wire rated to 300 V, 60 A. Low installation torqueing for “hot” leads allows reliable connections to be made quickly, easily and resist loosening during operation. A solid-copper grounding strap on the center pole assures safety.

Construction and Finishes

ERTB Terminal Blocks are molded in Heyco’s own state-of-the-art U.S. plant of impact-resistant polycarbonate with a flammability classification of 94V-0 and a temperature rating of 125 C. ERTB Terminal Blocks are UL recognized and certified by the Canadian Standards Association. Free samples are available upon request.
