# FP_ZR_20 enclosure extension frame CAD drawings for FP_ZR_20 help place the selected enclosure extension frame and coordinate its mounting, connection access and service space. An extension frame forms part of a selected enclosure assembly. Its mating surfaces and the extra interfaces it introduces need to be shown alongside the adjoining enclosure components. ## Equipment and file summary Equipment / resource: FP_ZR_20 enclosure extension frame Manufacturer: Hensel Resource type: Named drawing reference Listed file formats: STP Listed files: 2 Available previews: Manufacturer source / drawing request Recorded revisions: Confirm the revision with the manufacturer Source checked: 2026-10-14 Download access: Use the official manufacturer source or request the exact drawing ## Related GA references - [Hensel ENYSTAR distribution enclosures](https://eloragrid.ai/objects/europe-hensel-enystar) - [Hensel FP_ZR_20 enclosure extension frame](https://eloragrid.ai/objects/ga-fp-zr-20-8d5e8adca4d3) - [Switchgear panel](https://eloragrid.ai/objects/switchgear-panel) - [Switchboard](https://eloragrid.ai/objects/switchboard) - [Ring main unit](https://eloragrid.ai/objects/ring-main-unit) Canonical page: https://eloragrid.ai/tools/cad-library/equipment/drawing-fp-zr-20-8d5e8adca4d3 Manufacturer: Hensel Entry type: Named drawing reference Part number: Not specified — select exact configuration Category: Switchboards & switchgear Formats: STP Market discovery: UK / Europe / Global Access: Direct download Official source: https://www.hensel-electric.de/de-de/service/downloads/digitale-produktdaten/3d-step.php Manufacturer evidence: https://www.hensel-electric.de/de-de/service/downloads/digitale-produktdaten/3d-step.php Source checked: 2026-10-14T00:00:00.000Z Original CAD is retained privately; explicit publisher restrictions keep public downloads on the official route.

These paths retain their own archive and native checksums in the file evidence. ## In plain English ### What the equipment does An enclosure houses equipment and its connections. Its construction provides the environmental and access protection specified for that enclosure. ### A simple example In a substation marshalling cabinet, the enclosure houses terminals and interfaces between switchyard cables and control-building wiring. ### What the drawings help you do The acquired source archive contains ENYSTAR_Zwischenrahmen/FP_ZR_20.stp, a 218,866-byte STP native file.

It identifies the named enclosure extension frame drawing in the official ENYSTAR enclosure and distribution-system STEP archive. Its native member path and checksum are recorded below; this is stronger evidence than a search result or an inferred catalogue number. ### Does this drawing include the complete installation? An enclosure component does not establish a finished assembly rating, environmental protection or accessory compatibility. Coordinate adjacent components, wiring and required working space separately. ### Which file should I use? Download the official original archive and select the recorded native member. Follow publisher access terms; this page does not replace the current manufacturer drawing or grant redistribution rights. ### Terms - CAD: Computer-aided design files used to prepare drawings and models. - Revision: The recorded version of a drawing or model.
