Overview
The Allen-Bradley 194R-FJ030P3 is a rotary disconnect switch from the proven 194R series, designed for reliable power isolation in industrial control and motor applications. This enclosed variant combines IEC compliance with a compact footprint, making it ideal for panel-mount installations requiring safe, quick-access power disconnection at 30A, 690V AC.
Key Features
- 30 Amp current rating — handles medium-power machinery and motor circuits
- 690V AC rated — meets international voltage standards for industrial drives and VFDs
- IEC 60947-3 compliant — tested for switch disconnection and isolation per global standards
- Enclosed design — thermoplastic or metal enclosure protects contacts and operator; available with rotary handle or rod/cable actuation options
- 4-pole configuration — controls three-phase circuits plus optional additional control circuits
- Touch-safe construction — isolated phases minimize risk of accidental contact during operation

Typical Applications
- Motor disconnect means — at-motor or in-panel isolation for AC induction motors
- Industrial drive circuits — power isolation for frequency inverters and soft starters
- Machinery control panels — safe lockout/tagout (LOTO) point for maintenance
- Three-phase distribution — control circuits in manufacturing and process automation systems
- Service entrance isolation — UL-compliant disconnecting means for larger machinery
Compatibility & Replacements
The 194R-FJ030P3 is part of the extensive Allen-Bradley 194R Rotary Disconnect Switch family, which ranges from 20 A to 1250 A. Direct replacements within the 194R line include other 30A enclosed variants. The FJ prefix denotes an enclosed unit; open-style equivalents include the 194R-NJ (fused open) and 194R-NN (non-fused open) series at the same 30A rating.
For applications requiring a non-fused version, the 194R-FN030P3 (non-fused enclosed) is a direct functional replacement. Ensure voltage, pole configuration, and enclosure material match your application before substituting. All 194R switches share the same rotary mechanism and standard mounting footprint for quick swaps in existing installations.
