Applications

Where Our Products Are Used

Brass terminal blocks are designed as fixed connection components for low-voltage power distribution and control wiring. The conductive path is based on brass with selectable copper grades, paired with a PA66 insulating housing that provides flame retardancy and mechanical stability, making the product suitable for industrial electrical cabinets and automation assemblies.The integrated anti-loosening design reduces contact resistance drift under thermal cycling and vibration, while DIN rail compatibility supports rapid panel integration for OEM procurement, system integration projects, and wholesaler inventory standardization.

What is a Brass Terminal Block?

A brass terminal block is an electrical interconnection component that uses brass (with selectable copper options) as the conductive element and a molded PA66 insulating body to safely distribute power or control signals between wires inside electrical panels.

Why is PA66 used as the housing material?

PA66 is used because it delivers mechanical strength, dimensional stability, and flame-retardant performance that meets UL94 V-0 or equivalent requirements, which is critical for safety in industrial control and distribution equipment.

How is the product installed?

The terminal blocks are designed for standard DIN rail mounting, allowing direct snap-on installation in control cabinets, distribution boards, and automation enclosures without additional brackets.

What is the service life and reliability of industrial terminal blocks?

With high-quality materials and proper installation, industrial terminal blocks can operate reliably for many years, even under high temperature, vibration, and humidity conditions. Regular inspection further extends their lifespan.

What industries commonly use terminal blocks, and what support is available?

erminal blocks are widely used in automation, power distribution, renewable energy, transportation, and telecommunications. We provide technical consultation, product customization, and after-sales support to ensure seamless integration into your systems.
