Schneider Electric Harmony XB4 Series Pull Release Emergency Stop Push Button, Panel Mount, 22mm Cutout

The Harmony XB4 metal range of modular control and signalling units combine simplicity of installation, flexibility, and robustness. This range meets the requirements of many industrial applications. These units are either complete products or separate components for customer assembly.

The performance of the Harmony XB4 range meets the most demanding international standards and approval, such as:
• EN/IEC, CE marking, UL, CSA, CCC, EAC, JIS, NEMA, and marine approvals
• Protection against ingress of solid objects, dust, and water: IP 66, 67, 69,69K and type 4X
• Shock protection level up to IK06
• High vibration resistance with shake proof connection screws (periodic retightening unnecessary)
For outdoor applications, the operating temperature oscillates from -40 °C to +70 °C/-40 °F to +158 °F

The range of XB4 can be used in the following applications:
•Industry (machine and control panels in packaging, material handling, material working, and pumping)
•Building and infrastructure (energy distribution panels, public works, restaurants, commercial buildings and airports)

This ZB4BT84 is a chromium-plated unit, which has mechanical durability up to 300000 cycles. The resistance to high-pressure washer is 7000000 Pa at 55 °C, distance: 0.1 m.

• Environmental information about the unit
• Minimal use of hazardous substances in, and beyond, compliance with regulations (RoHS, REACh)
• A promise of sustainable and environmentally friendly performance
• Product Environmental Profiles (PEPs) for easy carbon footprint calculation
• End-of-life instructions for reduced cost and optimised recycling

A general-purpose push button switch is used for controls, for example: to start machine operation or simply to switch modes. An emergency stop pushbutton switch, however, is mainly used as a safety measure to stop hazardous events.

This is a Class 1 conforming to IEC 61140
