DIN rail and board accessories: enclosure, rail, blanking strip and door

Guides 19/10/2026 By INVENTĀRS 17 views 0 reviews

Once the protection scheme is clear, the remaining question is where the devices actually sit. A modular consumer unit, an empty metal box with a mounting plate and a loose DIN rail are not the same product. This guide helps you choose the enclosure, rail, blanking strip and door. Device ratings still belong in the board bill of materials — this page does not retarget “distribution boards price”.

Information, not a design. LBN 261-15 p.55: installation under a certified specialist. P.17: equipment must withstand site conditions. Conformity to LVS EN 61439 sits with whoever assembles the board (LEVA v1.1, 09.02.2026).

What it is	Where it fits	What it is not	Example
Modular consumer unit	DIN devices in rows, indoor or IP65 outdoor distribution	Not an empty “box with a plate”	ABB UK636E3 flush, 36 SU, IP30, 622×384×97 mm; ABB UK612E2 12 SU, IP30; Gewiss Q-DIN 10 10 modules, IP65, IEC 16/32 A flanges
Empty metal box + plate	Terminals and small gear when you fit the rail yourself	Not a 36-module Volta	THORGEON 22043 IP66, 300×250×150 mm, 1.2 mm steel, 2.0 mm galvanised plate
Floor-standing field	Larger indoor gear with a declared IP	Not a 12-module flat board	ABB TL212G 1850×550×275 mm, 2 fields × 12 rows, IP55, class I earthed

IEC/EN 60715 35 mm rail (TH35) is the standard profile. One module is about 17.5–18 mm. ETI DIN rail 1 m — length 1 m; TH35-7.5 vs TH35-15 is not split on this card — use the datasheet if the project needs a height. We do not publish drilling steps.

A 45 mm cut-out stays open if the row is short. Blanking covers unused modules. LBN 12.1 requires space for later work — spare modules stay, but they are covered. Hager VZ415 universal 12M, RAL 7035. Hager JP014 Gamma 13, 13M. Eaton NBP-1000-W 45 mm, 1 m, cut-to-length, RAL 9016. A 12M strip is not an 18M row — Hager VZ416 is 18M.

Hager VA36T — Volta surface 3-row steel door. Hager VF108PD Golf 8M. Doors are system parts. IP holds only with the maker’s cover and glands — IP and glands. Q-DIN IP65 is not Volta IP30. Marking: cable marking. Metering: DIN energy meters.

Check availability on the card. Distribution boards and DIN gear. Boxes: junction boxes. Protection: MCBs and RCDs.
