Bulletin 194 Disconnect Switches

The Allen-Bradley Bulletin 194 Disconnect Switch family is a broad line of IEC and UL-rated rotary disconnect switches, switch actuators, and associated accessories designed for motor branch-circuit isolation and load control across a wide range of current ratings and installation configurations. The family spans multiple sub-bulletins — 194E (modular IEC switches up to 63 A), 194L (switch actuators in plastic or metal, available in multiple sizes and actuator types), and 194R (heavy-duty switches and accessories rated from 60 A through 630 A) — with over 900 catalog numbers covering the full spectrum of panel-mount and door-mount applications. Catalog-number structure encodes key attributes: sub-bulletin prefix identifies the switch type, frame size indicates current range (e.g., Size 4 in the 194L series), and pole configuration (3-pole or 4-pole) reflects circuit requirements. Popular in-stock examples include the 194L-HE4P-175I (Type P plastic actuator, Size 4), the 194R-60-C3 (terminal shield for 60 A disconnect switches), and the 194R-LNC11 (terminal shrouds for 400–630 A, 3-pole IEC non-fused switches). Terminal lugs, covers, shrouds, and screens are stocked across the full current range to support compliant installation.
