Miniature circuit breaker lock (PA66 pushbutton snapon) Why you need it Prevents accidental reenergization during maintenance or servicing by physically securing the breaker in the off position. Saves time for electricians and maintenance staff with a tool, onehanded installation. Durable and reliable in industrial environments where temperature, insulation, and mechanical wear matter. Key benefits and problem solving Fast, tool installation: Pushbutton snapon design lets technicians lock a breaker quickly by pressing the button manually, reducing downtime and simplifying lockout/tagout procedures. Longterm performance: Body and pushbutton are molded from PA66, a strength engineering plastic that provides electrical insulation, mechanical durability, and resistance to heat (50°C to +177°C). Broad compatibility: Works with a wide range of singlestage, multistage, and miniature circuit breakers without modifying panels or breakers, so you can standardize on one device for many installations. Compact footprint: Fits breakers with terminal/aperture spacing under 12 mm, making it suitable for dense panels and confined spaces. Features at a glance Material: PA66 (body and pushbutton) Temperature range: 50°C to +177°C Installation: Pushbutton snapon, manual operation Compatibility: Singlestage, multistage, and miniature circuit breakers (no panel/breaker modification required) Size fit: For apertures less than 12 mm apart Practical use scenarios Industrial plant maintenance: Secure circuit breakers during scheduled repairs or machine servicing to eliminate the risk of accidental restart. Electrical panel servicing in tight spaces: Compact design fits closely spaced breakers in control cabinets and distribution boards. Field service and construction sites: Rapid snapon installation lets crews lock out breakers quickly during temporary work or equipment changeover. What makes it stand out Combines proven PA66 material performance with a simple, secure snapon mechanism for dependable lockout in demanding environments. Designed for versatility and spaceconstrained panels while avoiding the need for breaker or panel modification. Compatible, durable, and easy to use — a practical safety device for routine lockout/tagout and breaker protection tasks.
