Barrier Terminal Block

Barrier Terminal Blocks are electrical connection components designed with isolated terminal sections to provide safe and reliable wire connections. Using a screw clamping structure, these terminal blocks ensure secure wire fixing and stable electrical performance while improving insulation protection between circuits.

Barrier terminal blocks support wire sizes from 0.5mm² to 6.0mm² and are available with multiple pitch options ranging from 6.35mm to 14.0mm. Different designs with covers and without covers are available to meet various installation environments and protection requirements.

As a professional terminal block manufacturer, we provide a wide range of barrier terminal block solutions with customization options for pitch, poles, housing structure, materials, and colors. Our products are designed in accordance with international standards including IEC 60998, UL1059, and CSA C22.2 No.158.

Barrier terminal blocks are widely used in industrial control equipment, power distribution systems, lighting systems, instrumentation, automation equipment, and industrial electronics. We provide OEM and ODM services covering structural design, tooling development, prototype production, and mass manufacturing support.
