800T-A1A
現行品800T 30mm Green Flush Push Button 1NO
従来のAB 30mm ヘビーデューティープッシュボタン。
主な用途
800Tは800Fの前身モデルです。現在でも北米の多くの古いプラントで使用されています。30mmのヘビーデューティ仕様で、タンクのように頑丈に作られています。1980年代から2000年代のAB機器を維持する場合、これらが使用すべきボタンです。
互換性
Legacy 30.5mm Allen-Bradley heavy-duty. Still manufactured by Rockwell. 800F is the modern 22mm replacement but requires re-drilling panel cutouts from 30.5mm to 22mm (or using adapter plates). 800T contact blocks are specific to 800T — not shared with 800F.
修理 & メンテナンス
800T buttons are virtually indestructible. When they fail, its almost always the contact block. The 800T-XA/XB contact blocks are still available from Rockwell.

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.
