Procurement snapshot

Only hard product-level facts retained from the cited source route are shown below. A missing buying field is handled separately, rather than estimated from the listed series.

Current and topology
N43 supports direct current measurement to 63 A or indirect CT measurement in three-phase three- or four-wire systems. [S4]
Quantities and protocol
It reports voltage, current, active, reactive and apparent power and energy, power factor, frequency and THD with RS-485 Modbus. [S5]

Evidence scope

The retained official product route documents: LUMEL documents N43 as a rail-mounted three-phase power-network meter. This dossier uses that cited route as the editorial scope. [S6]

The retained research coverage separates company identity from the named product evidence. It does not turn one model or series into a claim about unlisted company-wide operations. [S8]

Procurement fit

The N43 is a finished meter, not a standalone display, and should be specified as an assembled unit for installation on a DIN rail within switchboard or distribution panel layouts. Direct measurement is supported to 63 A; installations above that threshold require current transformers. Alarm, pulse and communication options are noted as N43-family scoped, so variant selection is necessary when ordering. Availability, lead time and authorized distribution channels are not publicly documented in the source record.

Technical capabilities

The N43 performs direct current measurement to 63 A or indirect measurement via current transformers in three-phase three- or four-wire systems. Reported quantities include voltage, current, active, reactive and apparent power and energy, power factor, frequency and THD. Communication is handled via RS-485 using the Modbus protocol. Accuracy class, update rate, input voltage range, auxiliary supply and display specifications are not publicly documented within the supplied entry and must be obtained from the manufacturer's data sheet.

Markets and applications

The documented topology covers three-phase three-wire and three-phase four-wire networks, with direct connection rated to 63 A and indirect connection via CTs for higher currents. The measurement set includes voltage, current, active, reactive and apparent power and energy, power factor, frequency and THD, which align with energy monitoring and sub-metering use cases on industrial distribution feeders. Single-phase operation and application environments outside the listed topologies are not publicly documented in the source record.

Evidence limitations

The source record confines the entry to multifunction power meters, specifically the LUMEL N43. Company history, founding year, employee count, revenue, export markets, customer references and quality certifications are not publicly documented. Detailed mechanical dimensions, display specifications, auxiliary supply range, accuracy class, harmonic order limits and type-test certificates are not publicly documented. Pricing, lead time, warranty terms and the authorized distributor list are not publicly documented.

Editorial summary

LUMEL S.A. is a manufacturer based in Zielona Gora, Poland, listed in this directory under the multifunction power meter category. The documented product entry covers the LUMEL N43, a rail-mounted three-phase power-network meter. The series is presented as a finished instrument rather than a display module, and the entry does not enumerate alarm, pulse or communication variants beyond family scope. All facts below are taken from the manufacturer record as supplied and not supplemented with external sources.

Evidence states describe the public material reviewed for this profile; they do not rate the company or assert an undisclosed fact.

  • Identity and location are retained from the cited official source. Product facts and visual are limited to LUMEL N43 rail-mounted three-phase power-network meter; no unlisted company-wide performance, availability, production or revenue claim is asserted. [S8]Company-stated

Frequently asked questions

What Multifunction Power Meter product is documented for LUMEL S.A.?

The retained product material names LUMEL N43 rail-mounted three-phase power-network meter. The dossier keeps this as a product-level statement rather than using it as a claim about the company's entire catalogue. [S6]

Which published current and topology should a buyer compare?

The cited product material records: N43 supports direct current measurement to 63 A or indirect CT measurement in three-phase three- or four-wire systems. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S4]

Which published quantities and protocol should a buyer compare?

The cited product material records: It reports voltage, current, active, reactive and apparent power and energy, power factor, frequency and THD with RS-485 Modbus. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S5]

Which common buying fields are not published in the retained sources?

The retained source packet does not publish Annual sales, Availability or stock. Those fields are intentionally left out of the procurement snapshot rather than inferred from a related series, a product image or the company identity. [S8]

Research notes

The retained first-party packet supports a richer product-level reading surface, but it does not yet contain 600 words of distinct cited content. This noindex dossier remains in reviewing status until additional source-backed facts are retained.
