Abb cr104pbg01u1a2 Pushbutton 30.5mm Momentary 1NC

Product Description

The ABB cr104pbg01u1a2 is a heavy-duty, non-illuminated pushbutton switch designed for industrial panel-mount applications. Built to the 30.5mm mounting standard, this momentary-action unit ships with a flush head and a 1 normally closed (NC) contact configuration. An OFF nameplate is included, and multi-color inserts in red, green, yellow, and black allow field customization to match panel labeling conventions. The watertight and oiltight construction makes it suitable for demanding environments where moisture, coolant, or hydraulic fluid exposure is a real concern. Licensed electricians and industrial control technicians are the primary installers.

This pushbutton is intended for panel-mount installation in industrial control enclosures, machine tool stations, and process control panels. Its momentary action means the contact state changes only while the button is depressed and returns to normal when released, which suits stop-circuit and interlock applications. The included OFF nameplate and multi-color insert kit make it practical for multi-function control stations where clear operator labeling is required. The watertight and oiltight rating supports installations in wash-down zones, manufacturing floors, and outdoor enclosures subject to environmental exposure.

Compatibility

Part of the ABB CR104 family of heavy-duty industrial pushbuttons and control devices, designed as a panel-mount control component for industrial enclosures and control stations using the 30.5mm standard mounting format.

Installation Notes

Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the control panel before removing any existing device or making new connections. The 30.5mm panel cutout must be clean and free of burrs before mounting. Verify contact rating against the control circuit load before commissioning.
