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.

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.

0.5–420–12 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.

0.5–2.520–14 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.

Inside a junction boxLoose in a junction box, light fitting or electrical box; no fixing holes or DIN clip [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.

9 mm [4]
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.

CopperRed 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.

Polycarbonate (PC) [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.

Module: 9.1 × 39.3 × 14.5 mm (width × length × height); kit case: 165 × 87 × 17 mm9.1 mm width from the case label (“Size: 9.1x39.3x14.5mm”) [3]
Weight — what it means

The device’s weight without packaging, per the maker.

182 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).

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 wiresEach module joins 2 wires (in–out, two levers). Modules clip together into groups of 2, 3, 4 or more lines; each line stays separate [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.

LeverRaise the lever to 90°, insert the wire and close it; the wire can be removed and replaced [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.

3434 identical modules in a case [3]
Package contents — what it means

What comes in the box, per the maker.

34 lever splicing connectors (1-in/1-out modules that clip together), plastic storage case [3]
