Provides a simple, visible physical barrier that helps reduce the risk of unexpected power restoration. Size and compatibility Designed for rocker switch width: 10 mm (0.39 inch). Accepts a padlock with a maximum shackle diameter of 9 mm (0.35 inch). Compact, universal shape fits a wide range of single, double and triplehandle circuit breakers. Material and durability Made from polyamide for mechanical strength and good toughness. Provides electrical insulation, heat resistance and friction resistance for reliable performance in typical electrical environments. Durable construction for long service life under repeated use. How it solves problems Prevents accidental reactivation of breakers during servicing, protecting personnel and equipment. Blocks unauthorized switching to maintain control over energized circuits. Compact universal design reduces the need for multiple device types across different breaker configurations. Practical applications (use scenarios) 1. Maintenance and : Electricians secure the breaker rocker before servicing equipment to comply with lockout/tagout practices and avoid accidental startup. 2. Industrial operations: Facilities use the device on productionline breakers to prevent unauthorized operation during shift changes or machine adjustments. 3. Building management and safety: Property managers install the device on distribution panels to control access to critical circuits during inspections or tenant work. Notes for use Verify rocker width is 10 mm (0.39 inch) and padlock shackle does not exceed 9 mm (0.35 inch) before installation. Intended for use on single, double and triplehandle breaker configurations; confirm fit on your specific breaker model. This accessory delivers a compact, durable and compatible solution for securing rockertype circuit breakers while providing insulation and heatresistant performance through its polyamide construction.
