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.
Evidence scope
The retained official product route documents: thuba documents a named completed Ex terminal and junction-box family. 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
Procurement evaluation should treat the offering as a configurable family rather than a stock SKU. The documented scope covers customer-specific terminal arrangements and large terminal compartments intended for application-driven layouts, and the source material explicitly states that the facts do not imply one universal terminal layout. Buyers specifying Zone 1, 2, 21 or 22 coverage will need to confirm terminal count, conductor cross-section, and gland configuration on a per-order basis.
Technical capabilities
The Ex e family is designed for Zones 1, 2, 21 and 22 and is constructed in stainless steel. Documented construction features include customer terminal arrangements, large terminal compartments, and the ability to retrofit certified cable glands. Metal variants of the housing are stated to support EMC-oriented construction. The referenced design standard is EN 60079-7. No further electrical ratings, IP code, ambient range, or temperature class are stated within the documented facts.
Markets and applications
The series is intended for hazardous area installations where increased safety terminal and junction box enclosures are required, covering both gas atmospheres (Zones 1 and 2) and dust atmospheres (Zones 21 and 22). Plausible deployment contexts include industrial process plants and skidded equipment packages where EN 60079-7 compliant enclosures are specified. Specific end-use sectors, geographies served, and reference installations are not publicly documented.
Evidence limitations
Several standard procurement fields are not publicly documented, including IP rating, temperature class, ambient temperature range, electrical ratings such as voltage and current, terminal cross-section range, enclosure dimensions, weight, surface finish, individual ATEX or IECEx certificate numbers, lead time, and pricing. Available documented information is limited to family-level scope, stainless steel material, applicable zones, retrofit cable gland provision, EMC-oriented metal variant construction, and the EN 60079-7 reference standard.
Editorial summary
thuba Ltd. is a Switzerland-based manufacturer headquartered in Allschwil that supplies the thuba Ex terminal and junction boxes series within the explosion proof junction box category. The series is documented to EN 60079-7, the European standard for increased safety electrical apparatus, and is offered in stainless steel. Documentation presents the offering at the product family level rather than as a defined unit, and no specific dimensional or electrical ratings are published within the available facts.
Compiled prose, not a quotation. It restates facts drawn from the cited rows above and adds none of its own. It is not itself a sourced record, so read the cited sections for the authoritative wording.
Not published in retained sources
These common buyer fields were explicitly outside the retained source coverage for this dossier. They are shown as omissions, not filled with a proxy, a related model or an assumption.
Research coverage
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 thuba Ex terminal and junction boxes; no unlisted company-wide performance, availability, production or revenue claim is asserted. [S8]Company-stated
Frequently asked questions
What Explosion-Proof Junction Box product is documented for thuba Ltd.?
The retained product material names thuba Ex terminal and junction boxes. 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 zone and terminal scope should a buyer compare?
The cited product material records: The Ex e family is offered for Zones 1, 2, 21 and 22 with customer terminal arrangements and large terminal compartments. Use the value as a product-level comparison point, while keeping the exact model and installation boundaries in the cited route. [S4]
Which published glands and construction should a buyer compare?
The cited product material records: Certified cable glands can be retrofitted and metal variants support EMC-oriented construction. 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.
