    RETROFIT CONTROL

    Add intelligent sequencing to existing breaker panels.

    The RBSC Retrofit Serial Breaker Panel provides a straightforward solution for adding remote power sequencing to any installation using Square D QO-style circuit breakers. Instead of replacing an entire panel, the RBSC mounts alongside the existing cabinet, connecting to motorized breakers to enable individual circuit control. This approach saves significant installation time and hardware costs, making it ideal for upgrading performance venues, houses of worship, and other facilities with established electrical infrastructure.

    Control is managed through the proven LynTec SC-10 board via standard RS-232 protocol, allowing for simple integration with third-party control systems. The energy-efficient design requires no holding current to maintain breaker state, ensuring cool, reliable, and long-term operation. With standard features like automatic load shedding and brownout protection, the RBSC delivers modern power control intelligence to legacy panels.

    FAQ

    FAQs about the RBSC Retrofit Panel

    Can this control non-Square D breakers?

    No, the RBSC is specifically designed to control Square D QO-style remote controlled motorized breakers and is not compatible with other brands or types.

    How does the RBSC connect to my control system?

    The RBSC connects via a standard RS-232 serial connection. For network-based control systems, you can use a third-party IP-to-Serial converter.

    Is on-site commissioning by LynTec required?

    No, the RBSC is designed for a simple setup. Addressing is handled by onboard jumpers, and no factory start-up or commissioning is required for operation.

    What do I need to buy besides the RBSC panel?

    You will need to purchase the appropriate number and type of Square D QO remote controlled (motorized) breakers separately to install in your existing panel.
