“AOSI has been a trusted supplier of terminal blocks in our panel manufacturing business. Their lead time, quality consistency, and support for custom labeling are excellent.”
“Great product and reliable service. The screw terminals stayed secure even under vibration, which is critical for our industrial machines.”
“We’ve integrated AOSI’s barrier blocks into our power control systems. Their wide pitch range and robust insulation make them ideal for high-voltage applications. Great for factories needing safe and efficient terminal solutions.”
“AOSI helped us source cost-effective yet high-quality terminal blocks for our distribution network. Their screw terminals with protective barriers improved safety and simplified technician maintenance.”
Barrier terminal blocks provide safe and reliable connections for high-current wiring. With screw clamps and built-in insulation barriers, they prevent short circuits and ensure clear separation between wires. Suitable for power systems, control panels, machines, and transport equipment.
Barrier terminal blocks offer robust, low-resistance connections for power converters, distribution units, and industrial UPS systems. Their clear separation between terminals enhances electrical safety in high-voltage circuits.
In HVAC systems and building control panels, barrier blocks provide reliable wire isolation and strong retention, helping installers prevent wiring errors and maintain long-term performance in varying climates.
For high-power motors, factory automation, and control systems, barrier terminal blocks withstand mechanical stress and vibration, keeping wires tightly secured and safely routed inside enclosures.
Used in locomotives, signal control, and onboard systems, barrier terminal blocks offer high insulation, flame-retardant materials, and vibration resistance—critical for stable performance in rugged transportation environments.
Barrier terminal blocks are used to connect high-current wires safely, with insulation barriers that prevent short circuits. They are commonly installed in power distribution panels, control systems, and heavy equipment.
Common pitch sizes include 6.35mm, 7.62mm, 8.25mm, and 9.5mm. The pitch determines spacing between terminals and helps match wiring layout needs.
Consider the following:
Yes, protective covers are available and recommended for added safety. They provide:
Yes. Many models are designed for 20A–125A or more, with solid screw-type connections and heat-resistant housing for industrial use.
Barrier terminal blocks typically use flame-retardant plastic (like PA66 UL94V-0) and brass or tinned copper contacts to ensure safety and durability.
