Aci 114889 Emergency Stop Push-button Control Station

Product Description

The ACI 114889 is a maintained-contact emergency stop push-button control station rated for use in industrial and commercial electrical control applications. The station features a single mushroom head operator in red, providing a highly visible and ergonomic actuator for emergency shutoff functions. The contact configuration is NO/NC (normally open/normally closed), and the switch action is maintained, meaning the button stays depressed after actuation until manually reset. Rated at 600 volts AC, this control station is built for demanding environments where reliable operator safety controls are required. Licensed electricians and control panel technicians are the primary installers of this device.

This push-button control station is suited for use in motor control circuits, conveyor systems, machine guarding panels, and similar industrial control applications where a dedicated emergency stop function is required. The maintained switch action ensures the circuit remains interrupted until an operator manually resets the control, supporting lockout and safety interlock workflows. It is appropriate for both new panel builds and field replacement of worn or failed emergency stop stations in existing control enclosures.

Key Features

• Maintained switch action holds the open or closed state after actuation without spring return
• NO/NC contact configuration supports series and parallel wiring in safety control circuits
• Mushroom head operator provides a large, easy-to-actuate surface for emergency stop use
• Red operator color meets common industry conventions for emergency stop identification
• 600 volt AC rating supports use across a wide range of industrial control voltage systems
• Legend marking reads Emergency Stop for clear operator identification at the panel

Compatibility

Designed as an OEM-style replacement or new-installation push-button control station for industrial motor control and machine safety panels requiring a maintained NO/NC emergency stop operator.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button station. Verify that the contact configuration (NO/NC) matches the wiring diagram of the target control circuit before making connections. Do not install in enclosures that do not provide adequate protection for the rated voltage environment.
