Barrier Style | Barrier Strip Terminal Blocks
Curtis Industries manufactures high quality barrier style terminal blocks, in single-row, double row and high voltage options to fit a variety of applications. Our barrier terminal blocks (sometimes called barrier terminals or barrier strips) are built with sturdy, thermoplastic materials to make them break-resistant and heat-resistant.
Single-Row Barrier Terminal Blocks
We manufacture 3250 series, 37000/38000 series, 43000 series, CB and CFT series, GFT/GB series, SE/SEI series single row terminal blocks. The 3250 series and 37000/38000 series terminal blocks are available with either open or tri-barrier style designs to meet a variety of wiring requirements. The 43000 series single row terminal blocks are manufactured with either base mount or feed thru styles. CB/CFT series have a compact barrier design for control and electric feed-thru applications with limited space available. GFT/GB series can be manufactured with feed-thru, surface connection or printed circuit barrier design for through-panel or sub-chassis applications. Series SE/SEI terminal blocks have internal terminals for miniature feed-thru printed circuit or surface connections.
