## Summary description

Tarel distribution board model 321 is an 8-module electrical enclosure designed to provide protected power distribution. It features a 32A/400V five-pole main input, a 16A/400V five-pole secondary input and three 16A/250V output circuits. Suitable for industrial or residential installations where segmented supply and multiple protected outputs are required.

## Long description

Tarel distribution board model 321 is an 8-module electrical enclosure engineered for protected power distribution in small industrial, commercial, and residential installations. The unit provides a five-pole main input rated 32 A at 400 V, a five-pole backup/secondary input rated 16 A at 400 V, and three protected output circuits each rated 16 A at 250 V. The compact modular format allows mounting of circuit-breakers and protective devices within a single DIN-rail housing, enabling segmented supply and simplified wiring for circuits that require separate mains or backup feeds.
Advantages
The distribution board combines a higher-capacity main feed with a lower-capacity secondary feed to allow prioritized and backup power arrangements. Its 8-module footprint makes it suitable for installations where limited panel space is available while still providing three separate protected outputs. The enclosure supports standard DIN-rail components and provides organized wiring paths, which helps reduce installation time and improves safety by keeping live parts enclosed and insulated.
Suitable for
Small workshops or service rooms requiring a separate backup supply.
Residential sub-distribution where one stronger input and one secondary input are needed.
Light commercial installations with multiple protected 16 A circuits.
Situations demanding a compact modular panel with three distinct outputs.
When it may not be suitable
This distribution board is not intended for systems that require a large number of circuits beyond the provided three outputs or for installations needing higher continuous current on all outputs. It also may not be appropriate where integrated advanced protection (such as built-in RCDs for every circuit or surge protection) is required unless additional devices are installed inside the modular space.
Key specifications
Module size: 8 DIN modules.
Main input rating: 32 A, 400 V, five-pole configuration.
Secondary/backup input rating: 16 A, 400 V, five-pole configuration.
Output circuits: three outputs, each 16 A, 250 V.
Suitable for DIN-rail mounting of protective devices and circuit breakers.
Enclosure type: compact modular unit for indoor electrical panels.
How to use
Mount the distribution board on a flat surface or inside a larger electrical cabinet following local electrical codes. Install compatible DIN-rail protective devices (MCBs, RCDs or combination units) inside the available 8-module space according to the desired circuit protection scheme. Connect the 32 A five-pole main supply to the designated main input terminals and the 16 A five-pole secondary supply to the backup input terminals. Route each of the three 16 A outputs to their respective loads, ensuring proper torque on terminals and correct phase, neutral and protective earth connections. Verify all connections and protective device settings before energizing the unit.
What to consider before purchase
Confirm that the provided three 16 A outputs and the 8-module capacity meet the number of circuits and protective devices you plan to install.
Ensure the 32 A and 16 A five-pole input ratings match the supply characteristics and earthing/neutral arrangements of your installation.
Check local regulations for required protective devices (RCD, surge protection) and whether additional modules are needed to accommodate them.
Verify available mounting space and clearance inside the enclosure or cabinet where the distribution board will be installed.
Usage recommendations
Use certified DIN-rail circuit breakers and protective devices that match the current ratings and intended functions. Perform wiring and commissioning by a qualified electrician and label circuits clearly to maintain safe operation and facilitate future maintenance.
