The Schneider Electric XB4 contact block has become synonymous with industrial and domestic switching in the recent past. Its popularity can be attributed to its flexibility, robustness, and ease of installation. The BX4 contact block has been designed to meet the requirements of numerous industrial applications. By virtue of being modular, they are available as complete products or as separate components. The XB4 block when complete is made up of a metal chromium metal bezel and is often accompanied by two NC or NO switches. It has screw clamp terminals which are used to fix it onto a surface.

Uses of the Schneider Electric XB4 contact block
The Schneider Electric XB4 contact block is used alongside pushbuttons (single return/ multiple headed pushbuttons), emergency stop mushroom head buttons, selector switches, key switches, and pilot lights.
Features
- Offers combined functions (contact and illuminated functionality)
- Are available as either a complete unit or subassemblies for user convenience
- Embodies screw clamp terminals, plug-in connector and spring clamp terminals.
- Ingress protection (IP 66 and IP 69K)
- UL and CE markings
- Approved and certified for meeting the EN/IEC, UL, NEMA, CSA CCC, and JIS
- Its screws are shake-proof (shock protection levels of up to IK06)
- Operates between-40 °C to +70 °C
Installation
Once you have decided the kind of switch to couple with the Schneider Electric XB4 contact block, drill a hole of Ø 22 mm.
Loosen the screw of the Schneider Electric XB4 contact block. Insert the designated operator (push button, emergency switch, etc.) Fasten it onto the contact block.
Tighten the screw to fasten the assembly. It is recommended that you tighten the screw up to a maximum of 1.2 Nm.
Why use Schneider Electric XB4 contact block?
Durability
The XB4 contact block can withstand 1000000 electrical cycles at 3600 Cyc/h. From a mechanical perspective, it can withstand 5000000 cycles.
Sturdy
The contact block operates in temperatures of -40 °C to +70 °C. It also offers ingress protection of IP20 thus conforming to IEC 60529 requirements. It has a vibration resistance of 5 gn.
It also offers a shock resistance of 30gn for 18 ms, half-sine wave acceleration and 50 gn for 11 ms, half-sine wave acceleration hence it conforms to IEC 600668-2-27 requirements.
Versatile
It can be used alongside pushbuttons, mushroom head emergency stop buttons, selector switches, Key switches and pilot lights among others
Ease of installation
The contact block is easy to assemble and install. This reduces the installation time and cost as well.
Summary
Besides being robust, the Schneider Electric XB4 contact block is readily available at both local outlets and online stores. It can work well in many environments and offers a reasonable life span. As such, its popularity is expected to grow going forward.
