3U Rackmount DIN Rail Power Distribution Unit

The 3U Rackmount DIN Rail Power Distribution Unit is designed for organized electrical power distribution and protection inside standard 19-inch rack cabinets.
It features a robust metal enclosure with a standard 3U rackmount design, providing convenient integration with network, telecom, CCTV, and industrial equipment racks.
The front panel provides 22 laser knockout positions, allowing flexible installation of circuit breakers according to actual project requirements.
A standard DIN rail is installed inside the enclosure for mounting MCBs, RCCBs, RCBOs, SPDs, relays, terminal blocks, and other DIN-rail electrical devices.
The unit supports various breaker configurations, including 1-pole, 2-pole, 3-pole, and 4-pole circuit breakers.
A 10-position copper neutral bar is provided for convenient and organized neutral wire termination.
A 10-position copper grounding bar provides a dedicated connection point for protective grounding conductors.
The removable front cover allows easy installation, wiring, inspection, and maintenance of internal electrical components.
Its standard 19-inch rackmount construction makes it suitable for installation in 600 mm and 800 mm deep rack cabinets.
This unit provides a practical and professional solution for integrating electrical distribution and circuit protection directly into rack-based systems.
