ACB retrofitting is the process of upgrading an existing air circuit breaker (ACB) with new components, technologies, or features. These modifications enhance the breaker’s performance, improve its safety features, and ensure compliance with modern electrical standards. Instead of replacing the entire breaker, retrofitting enables you to update the unit by adding new trip units, sensors, monitoring systems, control circuits, or other modern functionalities. This approach helps you maintain the integrity of your electrical protection system while optimizing the ACB's functionality for your current needs.
