Model and version3

Product type — what it means Splicing connectors join wires in a junction or wall box instead of twisting them. DIN-rail terminals sit in the panel next to the breakers and build up a terminal strip. A DIN adapter lets you fix a module without its own clip onto the rail.	DIN-rail terminalsDIN-rail terminal block kit for 35 mm rail (“DIN Rail Terminal Blocks Kit”) [1]
Barcode (EAN)	6920075740981SKU on the manufacturer’s website [1]
Standard	IEC 60947-7-1:2009 [4]

Housing and installation11

Solid wire size, mm² — what it means Which sizes of single-core (solid) copper wire the connector accepts, in mm². Home wiring typically uses 1.5 mm² for lighting and 2.5 mm² for sockets.	0.2–424–12 AWG [1]
Flexible wire size, mm² — what it means Which sizes of stranded (flexible) wire the connector accepts, in mm². Flexible wire usually comes from lights and appliances; a ferrule is needed only if the manual says so.	0.2–2.524–14 AWG [1]
Mounting — what it means How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.	35 mm DIN rail35 mm steel or aluminium DIN rail [1]
Wire strip length — what it means How many millimetres of insulation are stripped from the wire end before it goes into the connector. Too short a strip worsens the contact; too long leaves bare conductor outside the housing.	10 mmFrom the wiring steps: strip 10 mm (0.39″) and straighten the conductor [3]
Contact material — what it means The metal of the connector’s current-carrying part. Copper conducts well and tin plating protects it from oxidation; brass is stronger but conducts less well than copper.	CopperThe spec table says “Red copper” [1]
Connector housing material — what it means The plastic of the insulating housing. Polycarbonate (PC) is often clear so you can see whether the wire is fully inserted; polyamide (PA, nylon) is a common material for terminal blocks.	Polyamide (PA)Modified nylon PA66, flame-retardant (per the description) [1]
Plastic flammability class — what it means The housing plastic’s flammability class under the UL 94 standard. V-0 is the strictest of the common classes: the sample self-extinguishes within 10 seconds and drops no burning particles. It matters for products with 230 V inside or next to them.	Not stated by the manufacturer
Dimensions — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	Terminal: 8 × 48.2 × 30.8 mm (width × length × height); kit case: 190 × 132 × 23 mm8 mm width from the case label (“Size: 8x48.2x30.8mm”); length and height also on drawing [2] [4]
Weight — what it means The device’s weight without packaging, per the maker.	270 g [1]
Wire types	Copper wire: solid, stranded and flexible, in any combination [1]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CECE mark on the kit case label in the official infographic [4]

Power2

Rated current — what it means The highest continuous current through the connector per its documentation. It must be at least the rating of the breaker protecting the circuit; the wire size also limits the current actually allowed.	32 A [1]
Rated voltage — what it means The highest working voltage the connector insulation is rated for. Household 230 V mains needs a rating of at least 250 V.	250 V [1]

Control and features2

Wires per connector — what it means How many wires one connector joins. To branch one wire to several lights or sockets you need a connector with that many entries; sets can contain several kinds.	2 wiresFeed-through terminal: one lever clamp on each side (in and out); neighbouring terminals are bridged with a jumper bar through the centre slot [2]
Wire clamping — what it means A lever connector opens and closes with a lever: the wire can be removed and reinserted without tools. A push-in connector grips a solid wire as it is inserted. A screw terminal is tightened with a screwdriver and re-tightened over time.	LeverThe wire is inserted with the orange lever raised, then the lever is lowered; no screws to tighten [1]

Package contents2

Pieces per set — what it means How many connectors or items come in one pack. To compare the price per piece, divide the cost by this number; which kinds of connectors make up the set is in the note.	2020 terminals: 10 grey and 10 black (per the manufacturer’s infographic) [1]
Package contents — what it means What comes in the box, per the maker.	20 DIN-rail terminals (10 grey, 10 black), 2 jumper bars, 2 marker strips 1–10, 20 screws, end stops, clear storage case [1]

Differences between manufacturer documents

The table shows the primary document’s value. Below is what other manufacturer documents state; we check the supplied version’s label before sale.

Contact material: The description text on the same page says “brass metal body” — the manufacturer contradicts itself
Package contents: The number of end stops differs: 2 in the text, 4 in the kit infographic, which also shows 2 DIN-rail pieces not mentioned in the text
