1SFA616920R8047 ABB KA1-8047 Flexible Joint for Reset Pushbuttons

Why Choose the ABB KA1-8047 Flexible Joint?

The ABB KA1-8047 is a flexible joint accessory for modular reset pushbuttons, designed for use with the ABB KA1-8046 shaft in industrial control applications. Supplied under ABB order code 1SFA616920R8047, it forms part of ABB's modular plastic pilot device range and provides flexibility within shaft-operated reset mechanisms.

The KA1-8047 is particularly useful in applications employing a long reset shaft, where the flexible joint helps accommodate alignment variation between the panel-mounted reset operator and the device being actuated. This reduces the risk of mechanical stress or damage to the shaft while maintaining effective transmission of the reset action.

Designed specifically as an accessory for ABB reset pushbutton assemblies, the KA1-8047 works in conjunction with the KA1-8046 shaft. Its compact and lightweight construction makes it a practical component for machine building, control-panel manufacture, equipment maintenance and replacement applications.

Flexible Mechanical Connection for Reset Pushbuttons

Shaft-operated reset pushbuttons allow an operator mounted on the front of a panel or enclosure to mechanically actuate a reset mechanism positioned further inside the equipment. Where a long shaft is required, small alignment variations can place additional mechanical stress on the shaft and associated components.

The ABB KA1-8047 provides a flexible connection for these applications. Used with the KA1-8046 shaft, it allows greater tolerance for alignment variation and helps protect the shaft from damage, providing a practical solution for industrial reset mechanisms with challenging installation geometries.

Typical Applications

• ABB modular reset pushbutton assemblies.
• Long-shaft mechanical reset mechanisms.
• Industrial machinery control panels.
• Motor control and protection equipment.
• Electrical cabinets and enclosures.
• Machine building, maintenance and replacement applications.
