SMICO Push In Din Rail Mounted Terminal Blocks


The Push-in connection terminal blocks reduce the wiring time , and can support simply wiring in places where is only a little space available. You don't need any tool, just insert the cable is ok.

◆ Made from anti Inflaming Nylon PA 66, copper metal.

◆ Connecting, build bridges and labeling large or small conductor cross sections easily for feed through terminal blocks.

◆ Wiring can be handled in a limited space thanks to the compact design and front entry connection.

◆ With universal foot which can be installed on 35mm Standard Din Rail.

◆ Build electric potential distribution by using plug-in bridges in the terminal center.

◆ Available in all accessories: End covers, End Stoppers,Marker strips, Marker carrier, Plug-in bridge, etc.

SMICO’s comprehensive range of DIN rail mounted terminal blocks for power distribution applications offers a range of flexible, space-saving solutions optimized for simple handling and fast installation, even in restricted spaces and challenging conditions, and is available with screw-, PUSH-IN, and tension clamp technology. WPD screw-connection terminal blocks (pictured top right) have a unique form factor with offset screw heads and patented clamping yoke technology to ensure safe and comfortable connections at every echelon level in even confined systems and housings. They also have IECEx-approved self-extinguishing, halogen-free plastic housings with high finger protection per EN 50274, short circuit resistance per the SCCR standard, and four color choices: grey, blue, red, and black, and are ideal for distributing the energy and zero potentials fed into machines and plants one step further to supply applications including industrial motors. WPDB – North America DIN rail, screw-connection terminal blocks safely, flexibly, and economically distribute mains-born power sources (50–1,000VAC and 75–1,000VDC), accommodate large wire sizes and multipole assemblies — including single-, two-, and three-phase groupings — in a compact footprint, and ensure finger-safe connections in industrial applications including material handling, building automation, and power conditioning systems. PUSH-IN WPD terminal blocks for AMC motor connections (pictured bottom) have a unique, three-level design that enables quick and easy installation, safe, pluggable connections, and cross-level wiring in the smallest possible footprint and can even be used as an alternative to potential distribution. WPD terminal blocks with tension clamp connection technology, a universal contact system for all common conductor connection types (pictured top left), support compact power feed-in and distribution via large-cross-section wires and allow users to further distribute power within panels via standard cross-connections. The uniform position of the cross-connection channels allows for convenient potential distribution for wires with cross-section spanning 1.5–16mm2 for both broad application suitability and subsequent system extensions.

1.The reducing bridge allows terminal blocks with different nominal cross sections to be connected with

ease, e.g., a PT 10 push-in terminal block to a PT 2,5. Power blocks can be created quickly using the re-

ducing bridge.

2.The double function shaft can be used to connect any number of terminal blocks with two-position bridges.

The 2 to 50-pos.bridges allow up to 50 terminal blocks to be bridged in one step.

3.A jumping bridge is created by removing individual contact guides from the standard bridge. Two

potentials can then be routed in parallel. The contact points can also be marked.

4.The P-FIX isolated feed-through connec-tor, P-DI isolating plug, P-CO component plug, and P-FU cartridge

fuse plug can be used in the universal plug-in zone of the dis-connect terminal block.

5.A test plug with a 2.3 mm diameter is available for measuring lines. All measure-ment and test work can

be completed at speed using test adapters for 4 mm diame-ter test plugs and the modular test plugs.

6.As well as offering a testing facility in the double function shaft, all push-in technology terminal

blocks offer an additional test con-tact for test plugs with a 2.3 mm diameter.

7.Push-in COMBI terminal blocks are avail-able for the plug-in configuration of signal wiring. The system

is touch-proof and offers self-assembly plugs with extensive accesso-ries.

8.Auto flat-type fuse terminal blocks with a 4 mm2 conductor connection are available in the same shape as

the feed-through ter-minal blocks. All terminal blocks can be con-tinuously bridged with one another with

the double function shaft.

9.The compact lever-type fuse terminal blocks are of the same shape as the feed-through terminal blocks and

can be labeled and bridged continuously. A time-saving po-tential distribution is easily created using a

jumping bridge.

In-line terminal blocks, PT combined terminal blocks, high current terminal blocks

With the in-line connection technology, wires with a diameter of 0.25 mm or more can be easily connected directly without tools. With contact springs, the wires can be inserted easily and the connection quality is high.


With direct plug-in connection, the pre-treated rigid wire can be connected without tools, saving time

Easily insert wires, saving 50% of effort

The pull button is color-coded to ensure safe wiring and operation

No need to install tools, you can easily release the wire

Unified complete system accessories to reduce logistics costs

Push-in terminal blocks are part of the line system

PT combined terminal block

The in-line connection PT series terminal blocks are suitable for connecting various wires with a nominal wire diameter of 1.5 mm to 185 mm.
Just insert a rigid wire with a wire diameter of 0.25 mm or more or a flexible wire with a cold head into the wiring position, and the wiring is convenient and quick. The contact spring opens automatically, generating sufficient pressing force on the current bar. When installing a thin wire with a wire diameter of 0.14 mm? or more, use a standard screwdriver to unscrew the contact spring.
This series of terminal blocks takes full advantage of the complete system. Various connection technologies and standardized system accessories can be freely combined.

PTV combines the advantages of in-line self-locking technology and screw terminal blocks

The PTV terminal block combines the advantages of tool-free in-line self-locking connection and side access of screw terminal blocks. The terminal adopts the tool-free direct insertion self-locking connection technology, the required wire insertion force is small, the connection is strong in vibration resistance, and the wiring time is saved. In addition, it also adopts the side entry design, the wiring position is clear, and there is no bending radius. Thereby, the vertical wiring between the wiring terminal and the line trough is realized, and it is easier to paste and read the cable identification.

Detailed explanation of in-line connection technology

You can directly connect rigid wires or prefabricated wires with ferrules without tools.

The special spring design can easily insert rigid wires with a wire diameter of 0.25 mm or more and flexible wires with a cold press head to achieve a strong wire pull-out force.

Easily insert wires, saving 50% of effort.

By using the pull-out button, you can use various tools to loosen the wire without directly touching the live parts.

When connecting a flexible wire with a wire diameter of 0.14 mm or more without a ferrule, you only need to easily turn on the pull-out button when inserting it.

The pull button is color-coded to ensure safe wiring and operation.

Front wiring, easily connect various wires.
