Research Notes
1. Overview
The Allen-Bradley 800T-A3A is a heavy-duty 30.5mm non-illuminated momentary flush pushbutton from the Bulletin 800T/800H series, manufactured by Rockwell Automation (Allen-Bradley). It belongs to the long-established 800T 30mm device family, a metal-construction industrial-grade pushbutton line rated for the most demanding environments. The part number decodes as: 800T (30mm Bulletin), A (flush head non-illuminated momentary operator), 3 (orange cap color in the 800T color convention), A (standard contact block — 1 NO, 1 NC). The 800T/800H series is widely used in legacy and active industrial installations globally, though Rockwell has also promoted the newer 800F and 800H lines for new designs.
DATA QUALITY FLAG — COLOR MISMATCH: The catalog entry for this product lists the name as "800T 30mm Yellow Push Button 1NO." This is incorrect. All authoritative sources — including the official Rockwell Automation product page, the Rockwell configurator cutsheet, Radwell International, BDI Express, SMC Electric, ElectricSupplyHQ, Reynolds Company, Surplus Select, Breaker Outlet, BSP Automation, eBay listings, MercadoLibre, and multiple distributors — consistently describe the 800T-A3A as ORANGE. The catalog name and contact-count ("1NO") also misrepresent the standard contact config, which is 1 NO + 1 NC. Correction needed.
2. User Sentiment
No direct end-user forum reviews or ratings were found in the source set. Market commentary from IndusSwitch notes the 800T-A3A is "a reliable and versatile option for industrial applications" and acknowledges it "may be more expensive than some other options," citing its "durability and safety features" as justification. PLC Hardware and GES Repair both stock new and refurbished units, indicating continued aftermarket demand. Breakeroutlet describes Series T units as "bold yet functional, rugged yet attractive" — language drawn from the Rockwell product literature — and notes they "perform in the most demanding industrial environments." Pricing observed across sources ranges from approximately $9.99–$134.22 (IndusSwitch), $26.00 refurbished (Breaker Outlet), $44.99 new (PLC Toolbox), $89.86 list (Crawford Electric), suggesting wide market availability at various price points.
3. Real-World Applications
The 800T-A3A is used broadly in industrial control panels, machine tool start/stop circuits, conveyor controls, motor control centers (MCCs), and process plant equipment requiring durable panel-mount pushbuttons. WeSupplyUSA lists it under the "800H Push Buttons" product line used "in industrial control systems where dependable sensing, switching, motion, safety, or connectivity performance is required." Tienda Risoul (Mexico) describes it as "ideal for applications requiring multiple control functions in a single device, being a practical solution for industrial panels where space optimization and efficiency improvement are sought." The 30.5mm mounting standard is prevalent in North American and Latin American heavy industry, and the 800T series is a standard reference in North American NEMA panel construction.

5. Ordering & Compatibility
The 800T-A3A ships factory-assembled with a standard 800T-XA contact block (1 NO, 1 NC). Additional contact blocks can be added in positions 2, 3, and 4 using 800T series contact blocks (800T-XA, 800T-XB, etc.), per the Reynolds Company attribute listing. Compatible accessories include 800T legend plates (e.g., 800T-X517 rectangular aluminum engraved plates for 30.5mm devices). The part is stocked by major North American distributors (Radwell, Crawford Electric at $89.86 list, Kendall Electric, Kirby Risk, Routeco UK, Westburne Canada) and Latin American distributors (Acomee MX, Omega Automation MX, Electronical a la Plata). Used/surplus units available $12.99–$44.99 CAD/USD. The base operator without contacts is 800T-A3 (no contacts); 800T-A3A adds the standard 1 NO/1 NC block.
6. Known Issues
No significant field defects or recall notices reported in the source set. One Breaker Outlet listing describes used units as "like new" and correctly identifies the color as orange in the product title while briefly and erroneously also using the word "Green" in the body copy — likely a copy-paste error from another listing, not a real product variant. The main data-quality concern for this catalog entry is the catalog name mislabeling the color as "Yellow" and the contact count as "1NO" (should be 1NO+1NC); all sources without exception confirm ORANGE color and 1NO-1NC contacts. This mirrors the color-mismatch pattern previously flagged for sibling 800T-A2A.

取付クイックリファレンス
Panel cutout: 30.5mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

トラブルシューティング
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
