J42The screw, collecting strip and press frame are sepa-
rately made of high strength alloy copper, electrolytic
copper and copper alloy. The metal surfaces are plated
with nickel for protection. Self-locking function can pre-
vent the screws from loosing.
High elastic copper press strip makes the contacts
more reliable.
The cover is made of imported Nylon 66, which has
good flexibility and its flame class reaches V0.
The leads need n t pretreatment.
Able to resist the rigorous industrial environment.
We can offer many types of function terminals such as
universal, experimental, fuse, and earthing types.Universal Type
Universal terminals can be mounted on both U-type
and G-type rails, making leads convenient pass
through.
Experimental Type
Experimental terminals can make kinds of test con-
nection of the secondary circuit of current trans-
former conveniently.
Disconnecting Type
Disconnecting type terminals are widely used in in-
dustrial automation field, convenient for users' test
and inspection.
Earthing Type
Earthing type terminals have yellowish green insula-
tion cover of international standard. The metal foot
of the ground terminal is connected with in rail elec-
tricity. And the rail can be used as the earthling bus.
Fuse Type
Fuse type terminals, in which the fuses can be
loaded, can open upward and can be fixed at the
end position.
Double-layer Terminal
Double-layer terminal has the characteristic of
saving space.Look from side,there is half thickness
of ordinary terminal between the upper and lower
layer wiring position. The top and bottom layers all
have to be connected.Universal Terminal 1.5 2.5

Terminal block, in the context of electrical engineering, refers to a type of component used for connecting, disconnecting, and organizing electrical conductors or wires. It is essentially a device with multiple insulated sockets or terminals, which provide a mechanical interface for attaching, splicing, or terminating electrical cables and wires. These blocks are commonly found in various applications, such as panelboards, junction boxes, control panels, and distribution systems, allowing for easy assembly, maintenance, and modification of electrical circuits. The design may vary depending on voltage ratings, current carrying capacity, number of connections, and compatibility with different wire sizes. Proper usage and connection of terminal blocks play a crucial role in ensuring the safety and functionality of an electrical installation.
