Where Our Products Are Used

Four Phase Distribution Block is a fixed terminal distribution component used to split and organize four-phase power lines within low-voltage switchboards and control cabinets. The design integrates a copper conductive core with an insulated PA66/94V-2 housing, positioning the component as a compliant, heat-resistant, and mechanically stable solution for busbar-to-circuit distribution.Four Phase Distribution Block is primarily applied in industrial power distribution panels, motor control centers, and equipment control cabinets where multiple branch circuits must be fed from a single four-phase source while maintaining clear phase separation and standardized wiring layout.

OEM Electrical Equipment

Terminal blocks for OEM equipment offering compact design, stable conductivity, and customized solutions for diverse electrical applications.

What is a Four Phase Distribution Block?

A Four Phase Distribution Block is an electrical terminal device used to distribute four-phase power from a main feed to multiple outgoing circuits inside industrial distribution panels.

How is the current rating selected?

Selection should be based on whether the required load falls within the 125A–400A range, ensuring that operating current does not exceed the rated capacity of the Four Phase Distribution Block.

Why is PA66/94V-2 housing used?

PA66 material with a 94V-2 rating provides defined flame resistance and thermal stability, reducing the risk of insulation degradation under normal operating temperatures.

Which standard does the Four Phase Distribution Block comply with?

Four Phase Distribution Block conforms to IEC 60947-7-1, which specifies requirements for terminal blocks in low-voltage switchgear and controlgear assemblies.

Where are Four Phase Distribution Blocks typically installed?

Four Phase Distribution Blocks are installed inside industrial switchboards, distribution cabinets, and control panels where structured four-phase power distribution is required.
