The three-phase distribution panelboard groups the branch circuits of an industrial installation: three-phase copper bus, main-breaker space and 4 to 42 circuits. It is built to IEC 61439-1/-2 or UL 67, installed per NTC 2050 article 384, and the product requires RETIE certification in Colombia.
The three-phase panel with main breaker is the distribution point for feeding industrial, commercial or service circuits from a three-phase service entrance. At TECTUL it is quoted by industrial line according to number of circuits, breaker type, space for main breaker, copper busbar, door with lock and required installation method. Unlike an industrial metal enclosure, this product is not only an empty enclosure: it is oriented to organize electrical protection and distribution. It also differs from a main breaker box because it allows several downstream circuits to be distributed, while the box usually houses the main or general disconnect breaker. To specify it properly, confirm load, number of outputs, protective device type, indoor or outdoor location, service entrance and project requirements under RETIE and NTC 2050.

| Criterion | Value |
|---|---|
| Branch circuits | 4 to 42, single- or three-phase |
| Bus bars | Copper; neutral and ground on separate bars downstream of the main disconnect |
| Main space | Sized to the main MCCB frame |
| Enclosure | Lockable door; IP rating per environment (IEC 60529) |
| Certification | RETIE-certified product; built to IEC 61439-1/-2 or UL 67 |
The neutral bar must be isolated from the enclosure and the ground bar bonded to it: they are joined only at the installation's main disconnecting means, per NTC 2050 article 250.
The price is quoted via WhatsApp according to number of circuits, protective device type, busbar, enclosure, protection rating and required accessories. TECTUL does not publish fixed prices for this product.
The three-phase panel is intended for electrical distribution with circuits and protective devices; the industrial metal enclosure is an enclosure for mounting control, automation or power components according to design.
The main breaker box mainly houses the general breaker or molded case circuit breaker. The three-phase panel distributes several circuits after the main protection point.
Yes. The lot describes a three-phase panel with space for main breaker, copper busbar and door with lock; the final configuration is validated in the quote.
Send number of circuits, system voltage, load type, installation location, cable entry and exit, required protection and delivery city.
It must be installed by qualified personnel, with firm fastening, grounding/earthing, circuit identification, proper ventilation or environmental protection and connection torque review.
Because NTC 2050 (art. 250) only allows joining them at the main disconnecting means: downstream, the neutral runs isolated from the enclosure and the ground bonded to it, so return current never flows through metal parts.
Number of circuits and their current, main breaker current and frame, system voltage, surface or flush mounting, and the installation environment (indoor, outdoor, dust) to set the IP rating.
