Regular inspection: Check the connection torque and protection status every 3-6 months, and promptly address any oxidation or looseness found.


Question 3: What are the structural differences, termination capabilities, and applicable scenarios of WAGO 884 and 885 series screw terminal blocks?

Answer:

(1) Structural differences

Comparison item 884 series (double screw) 885 series (single/triple screw)

Number of bolts 2 (fixed spacing, same specifications) 1 or 3 (single bolt independent, three bolts side by side)

The width of the terminal block increases with the increase of cross-sectional area (27-55mm). The single screw column is 17.8-33.8mm, and the three screw columns are the same as the single screw column

Installation method: snap on+bottom long circular hole (flat installation) snap on (DIN rail only)

Protective accessory special cover (can be cut, single/double-sided installation) 1m long transparent cover (with fixing clip, overall protection)

(2) End connection capability

884 series: Each stud can connect up to 2 cable connectors (back-to-back installation), supporting 2.5-300mm ² conductors and compatible with DIN 46234/46235 connectors;

885 series: A single stud can connect up to 3 cable connectors, and each stud of the three studs can be independently terminated (with different cross-sectional area conductors), supporting 2.5-120mm ² conductors.

(3) Applicable scenarios

884 series: suitable for high current, multi conductor parallel scenarios (such as main circuit of distribution cabinet, industrial motor power input), requiring 2 conductors to be connected simultaneously and with high current (such as 300mm ² conductor, 520A current);

885 series: Single screw is suitable for single circuit independent connection (such as instrument signal input, small equipment power supply); Three screws are suitable for centralized layout of multiple circuits (such as power distribution of multiple branches in a control cabinet), which requires saving installation space and a small number of circuits (within 3 circuits).
