Overview
The Allen-Bradley 194R-HS4E is an operating handle accessory for Bulletin 194R non-fused rotary disconnect switches. The 194R-HS4E is a Red/Yellow rotary disconnect switch handle that provides manual operation for safe isolation of electrical circuits during maintenance and service. The 194R-HS4E is specifically designed to operate with Allen-Bradley IEC and UL-rated disconnect switches within the Bulletin 194R series, and acts as the external manual operator for these switches.
Key Features
- Red/Yellow rotary disconnect switch handle for emergency and standard applications
- Features a defeater mechanism which allows the door of the enclosure to be opened even when the switch is in the ON position under specific conditions
- Padlockable design provides lockout/tagout (LOTO) capabilities for safety during maintenance
- Door-mounted rotary handle which has a coupling piece that enables the opening and closing of the control panel door independently from the position of the main contact
- Flexible operating and mounting options adapt to almost any application
