Inside the box, you'll find things like circuit breakers, busbars, terminal blocks, and wires. These parts control and distribute the electricity to different circuits safely. Clamping blocks and power distribution blocks (PDB) for the DIN rail are suitable for collecting and distributing potentials within sub-distribution boxes and switchgear. They are one-pole modular units with an interlocking dovetail feature that enables ganging of the blocks to create multi-pole configurations according to application requirements. Daier's. A distribution box is a low-voltage electrical enclosure that receives incoming power and distributes it safely to multiple outgoing circuits through protective and switching devices such as MCBs, RCDs, RCBOs, fuses, isolators, busbars, neutral bars, earth bars, and surge protective devices.
