Applications

Where Our Products Are Used

Two Phase Connection Block is a modular power distribution terminal designed for two-phase circuit connection and branch distribution within low-voltage switchgear and control assemblies. The design is based on IEC 60947-7-1 terminal technology, utilizing brass conductors and a flame-retardant PA66 housing to ensure stable current transmission and insulation performance under 500V systems. The block integrates defined input and output levels, allowing separate wiring zones for incoming and outgoing circuits while maintaining clear conductor routing inside cabinets.The structural configuration supports DIN-rail panel layouts and screw-mounted installations, making the Two Phase Connection Block suitable for standardized industrial enclosures. It is typically applied in distribution boards, automation control panels, motor control centers, and equipment terminals where reliable phase distribution, vibration resistance, and repeatable tightening torque are required.

What is a Two Phase Connection Block?

A Two Phase Connection Block is a fixed terminal component used to connect, distribute, and branch two-phase conductors within low-voltage electrical systems while maintaining standardized insulation and mechanical fixation.

How does a Two Phase Connection Block work?

It provides dedicated input and output interfaces where conductors are clamped by torque-controlled screws onto brass conductive bars, creating a stable electrical path while keeping circuits physically separated inside the housing.

Which conductor sizes are compatible with the Two Phase Connection Block?

The input side accepts rigid wires of 10–35 mm² and flexible wires of 10–25 mm², while the output side supports multiple ranges including 10–35 mm², 10–25 mm², and 2.5–10 mm² depending on the interface group.

How is the Two Phase Connection Block installed in a cabinet?

It can be mounted directly onto a 35 mm guide rail or fixed to a mounting plate using screws, allowing integration into different panel layouts and space constraints.

Why is IEC 60947-7-1 compliance important for a Two Phase Connection Block?

IEC 60947-7-1 defines mechanical strength, electrical clearance, creepage distance, and thermal performance requirements, ensuring that the Two Phase Connection Block can operate safely and reliably in industrial low-voltage systems.
