Product description:
Uk2.5b wiring terminal adopts frame screw crimping technology, which has the characteristics of firm locking wire, high pressure, and should not fall off.
Products made of high strength copper alloy production, good electrical conductivity, shell using nylon 66 engineering plastic, anti-aging, flame retardant, acid and alkali resistance advantages.
Installation using C45 same guide rail, can be perfect and circuit breaker, vacuum switch, AC contactor and other electrical products combined use.
The product uses the screw self-locking principle design, the main body is divided into screws, wire frame and conductor several mechanism parts.
The screws are M3-shaped. An M3 screwdriver is required during installation and assembly.
The wire pressing frame is made of high-strength copper zinc alloy, processed by high-speed punch press, punched by tapping machine, completed the basic production, and finally completed the production through heat treatment and electroplating.
And conductor and screw are also punch and tap two steps to complete production.
Uk2.5b terminal is one of the most widely used UK series terminal. The 2.5-square-meter diameter is suitable for most power distribution cabinets, control cabinets and communication cabinets.
The 2.5 square line is also suitable for fire protection and other warning equipment.

2.Product Design
1) Length 42.5 mm.
This length represents the widest length of the left and right ends of the product, not the installation size of the product, the installation uses a 35mm width guide rail.
2) Thickness 6.2 chamber meters.
The data of this width has more practical reference significance, because the reference thickness is needed in the selection of marking bar and short connector to decide the choice of accessories of the product.
3) The height of 40.8 chamber meters, this data is used for space control for reference and practical, such as the maximum space can accommodate height of 50 chamber meters, then in this case to choose 2.5 square terminals have UK3N and UK2.5B, but we need to use UK2.5B, the difference lies in the UK3N product height of 45.8 chamber meters, this use
Using UK3N, the height requirement of the guide rail will exceed expectations, which is limited by the space height.
3.A
ccessories Function
1. UK2.5B adopts D-UK1.5N baffle, which can only be used with UK2.5B and cannot be used on other models of products.
2. ZB4 label strip, due to UK2.5B's unique 4.2-meter thickness design, the choice of the label number can not be used with other specifications of the product, can only choose 4.2mm ZB4.
Its logo can choose between 1-100 numbers can also choose to use, LN,E logo ground line, zero line, live line and other letters, special characters can be customized, of course, can also choose to buy blank marking number design writing.
3. Bridge piece FB110-4, this product can not be mixed with other specifications of the product, its screw center spacing is 4.2 mm, exclusive to UK1.5N accessories.
4 Fixed parts,UK series terminals fixed choice is not the only one, can choose E/a UK double screw or three screws, can also choose to use SAK series products of EW - 35 fixed series, single screw lift, of course, fixed parts can also be used, so the fixed parts selection need according to the specific circumstances, all can use ordinary environment, choose three screw cold environment
E/UK or EW-35 can reduce the risk of pin breakage and improve product retention.
5· Mark holder usually has two options, UBE/D and UK-B1. The difference lies in the width and the installation method of the mark card. UBE/D is about 2cm in width, while UK-B1 is 1cm in thickness.
6 Mark holder KLM-A, this mark holder has the same function as the above mark holder, but the difference is that this product is fixed on the E/UK fasteners instead of directly on the guide rail when installed.
