250A 4 Pole Power Distribution Block with Cover Brass Neutral Bar
Designed as a centralized wiring solution for distribution boxes, cabinets and control panels, these terminal blocks enable neat and organized connection of multiple neutral and earth wires. High-grade brass conductors ensure stable current transmission, while flame-retardant housings eliminate short-circuit risks. DIN rail mounting greatly improves installation efficiency, making them ideal wiring accessories for building distribution, industrial control and automation applications.
