Circuit Protection

This Allen-Bradley circuit protection category covers over 3,500 SKUs spanning disconnect switches, switch hardware, and control power transformers commonly specified in industrial panel builds and machine safety applications. The Bulletin 1494U visible blade disconnect switches appear in 100 A, 200 A, and 400 A ratings with protective covers, while Bulletin 1494V variable-depth disconnect switch door hardware supports both right- and left-side mounting configurations, including Type 12 enclosure kits. The Bulletin 194L switch actuators and Bulletin 1497 global control transformers — ranging from 80 VA to 500 VA with common primary voltages including 208 V, 240/480 V, and 600 V — round out the category. Controls engineers and panel builders sourcing Allen-Bradley disconnects, actuator hardware, or replacement control transformers will find a broad selection of catalog numbers available here.
