This update to the RSBS Series soft starters addresses critical safety and compliance needs for HVAC systems using A2L refrigerants. The focus on maintaining existing designs while meeting stringent standards is a key advantage for manufacturers.

Problem As HVAC systems evolve to meet stricter safety standards, manufacturers face challenges in integrating components that comply with updated regulations. The shift towards A2L refrigerants, which are mildly flammable, necessitates components that not only perform reliably but also adhere to stringent safety certifications like UL 60335-2-40 and UL 60335-2-89. This is particularly critical for control panel applications where space and existing designs are constraints.

Solution Carlo Gavazzi has addressed these challenges with an update to its RSBS Series soft starters. These devices are now certified for use in systems with flammable refrigerants, specifically A2L types. The RSBS Series is designed for starting single-phase compressors up to 32 A, making it suitable for a wide range of HVAC applications.

Key technical features of the RSBS Series include: - **Compliance**: The soft starters meet UL 60335-2-40 and UL 60335-2-89 standards, ensuring they are suitable for A2L refrigerant applications. - **Fire Safety**: The enclosure materials are self-extinguishing, providing an additional layer of safety in the event of a fire. - **Compatibility**: The existing footprint and installation approach have been maintained, allowing for integration without redesign or requalification. This is a crucial advantage for manufacturers looking to upgrade their systems without significant overhauls. - **Compact Design**: The compact design of the RSBS Series makes it ideal for applications where space is at a premium.

"The RSBS soft starters are intended to help customers address these requirements without changing panel layout or adding requalification work," said a spokesperson for Carlo Gavazzi.

Results The RSBS Series soft starters provide a straightforward solution for manufacturers needing to comply with updated safety standards without compromising on performance or design. By maintaining the existing footprint and installation approach, Carlo Gavazzi has minimized the disruption to current manufacturing processes.

- **Certification**: The soft starters are compliant with UL 60335-2-40 and UL 60335-2-89, ensuring they meet the latest safety standards for A2L refrigerant applications. - **Ease of Integration**: The ability to integrate the RSBS Series without redesign or requalification saves time and resources for manufacturers. - **Safety**: The use of self-extinguishing enclosure materials enhances the overall safety of HVAC systems, which is particularly important given the mildly flammable nature of A2L refrigerants. - **Availability**: The products are available through Carlo Gavazzi sales offices and distributors in the Americas, providing easy access for manufacturers looking to upgrade their systems.

The RSBS Series soft starters offer a practical and efficient solution for manufacturers navigating the complexities of updated safety standards in the HVAC industry. By focusing on compliance, safety, and ease of integration, Carlo Gavazzi has provided a product that meets the needs of modern HVAC systems.
