Critical Components and Safety Features Detailed in the Catalog

Load-Rated Lockable Disconnect Switches

The catalog provides detailed specifications for the disconnect switch mechanisms that form the foundation of the e L-O-X system. Available in two configurations—rotary handle for 30-100 amp models and flange-type pull-down handle for the 200 amp model—these load-rated switches are specifically designed to be locked only in the OFF position, ensuring compliance with OSHA lockout/tagout requirements. The rotary disconnect switches feature robust construction with clear ON/OFF position indicators, while the 200-amp flange handle provides ergonomic operation for higher-current applications.

Each disconnect switch is rated for up to 600 VAC three-phase power and undergoes rigorous factory testing to verify proper operation under full load conditions. The catalog includes dimensional drawings, mounting specifications, and electrical connection details using terminal block configurations for simplified installation and maintenance.

Three-Phase Power Indicator System

A distinctive feature highlighted throughout the catalog is the integrated three-phase power indicator that provides immediate visual verification of electrical energy presence. This indicator serves dual purposes critical to safe lockout/tagout procedures: monitoring voltage presence on all three phases during normal operation and confirming complete energy isolation after the disconnect has been actuated and locked.

The power indicator is specifically designed to detect phase imbalances, alerting maintenance personnel to potential upstream electrical issues before they affect equipment operation. This proactive monitoring capability reduces unexpected downtime and equipment damage. The catalog details the indicator's voltage range (up to 600 VAC three-phase), visibility characteristics, and integration with overall system design.

Integrated Start (Test) and Stop Controls

The catalog extensively covers the integrated Start (Test) and Stop button functionality that distinguishes e L-O-X devices from conventional disconnect switches. The green Start button, normally open (NO), and red Stop button, normally closed (NC), are designed to integrate with existing machine control systems, operating at 24 VDC (1.5 amps) or 110 VDC (0.5 amps).

The Stop button enables operators to send a controlled stop command to machinery before actuating the disconnect switch, following proper shutdown sequences and preventing abrupt power interruption that could damage equipment or create safety hazards. The Start button serves a critical verification function during lockout procedures: after the disconnect has been locked in the OFF position, technicians can press the Start button to test that the machine does not energize, confirming effective isolation. This test-before-touch protocol, detailed in the catalog's operational procedures section, provides an additional layer of safety assurance beyond visual verification.
