Universal circuit breaker lock E203, single-pole, made of red ABS. Manufactured from high-quality materials, it is durable, robust, and non-conductive. The application is simple thanks to a screw mechanism for secure attachment that works without tools. It is universally applicable to common circuit breakers. The universal lock for single and multi-pole circuit breakers can be easily snapped on and tightened by hand without additional tools. With the E203 lock, securing can be done both vertically and horizontally using the multifunctional eyelet. This allows for a locking mechanism in series with multiple circuit breaker locks in conjunction with a cable lock.
