At COMECA, we offer **"Original Equipment Manufacturer" retrofit solutions** when we operate on our solutions. We offer you retrofitting other manuifacturer brands that are part of your equipment fleet. Our retrofit solutions renovate **drawers, circuit breakers, GemStart communicating protection relays version 1 to 4, MAC & SI type signalling cards, PLCs and other non-manufacturer elements of your switchboards**. ![vacuum contactor by a Rollarc 400 retrofit](https://info.comeca-group.com/hs-fs/hubfs/Vignette%20blog%20Hubspot%20(20).png?width=1200&length=1200&name=Vignette%20blog%20Hubspot%20(20).png) *Example of a vacuum contactor by a Rollarc 400 retrofit* By choosing a retrofit solution, you give a second life to your switchboard and extend the service life of your electrical installation. ## Retrofit benefits - Maintains characteristics of the original switchboard - Guarantees continuity of service - Investment control - Increases the level of security - Limits production stoppages - Increases reliability by reducing failures risk - Limits emergency interventions - Modernise equipment ## Equipment maintenance: circuit breaker retrofit Our specialists developed **retrofit kits to migrate to new generations of circuit breakers by mastering modification studies on your low-voltage switchboards**. Examples: circuit breakers from the C800 to C1250 range, CNP, Masterpact M series, M-PAC and Otomax, etc... ![circuit breaker retrofit](https://info.comeca-group.com/hs-fs/hubfs/Website%20vignette%20page%20solution%20(5).png?width=1200&length=1200&name=Website%20vignette%20page%20solution%20(5).png) Retrofit implementation: - Planned intervention with operating mode - Controlled downtime: factory-made solution - Maintain employee protection - Installation and testing according to manufacturer's procedures - Commissioning with COMECA technician's assistance [![Read our case study: Double clamp retrofit on NORMABLOC switchboards in the nuclear sector](https://no-cache.hubspot.com/cta/default/5464586/bf1a7171-36fd-487b-989a-9f3cf7379ebd.png)](https://cta-redirect.hubspot.com/cta/redirect/5464586/bf1a7171-36fd-487b-989a-9f3cf7379ebd) ## Equipment maintenance: drawer retrofit Retrofitting a drawer consists of replacing the old one whose equipment became obsolete. Often **we have to change the entire drawer to keep the correct elements arrangement. In this way the drawer is a tested unit that complies with the requirements of the standard**. Modernise a part in the drawer brings changes in the elements layout and sometimes it is not possible without change the other elements too. ![drawer retrofit](https://info.comeca-group.com/hs-fs/hubfs/Vignette%20blog%20Hubspot%20(21).png?width=1200&length=1200&name=Vignette%20blog%20Hubspot%20(21).png) ## Equipment modernisation: motor protection relay GemStart retrofit We provide compatible solutions with all GemStart version. [GemStart5](https://www.comeca-group.com/en/our-solutions/gemstart5-motor-protection-relay/) embeds same communication protocols as previous versions wich facilitates updates and allows you to keep existing networks. Thanks to our manufacturer know-how we developed [a retrofit solution named GemStart5-R](https://www.comeca-group.com/en/our-solutions/gemstart5-motor-protection-relay/gemstart-5-beyond-a-simple-motor-protection/gemstart-5-r-your-gemstart-upgrade-solution/) allowing you to replace old GemStart  version (1, 2, 3 and 4) by the last version GemStart5. ## Modernisation: needle equipment retrofit This modernisation consists in replacing needle-based equipment such as voltmeters and ammeters with a communicating measurement centre: - Digital display and small footprint - Obtaining additional information such as power ratings, harmonics measurement, power grid quality, etc. - Remote monitoring of your energy consumption ![Switchboard needle equipment retrofit](https://info.comeca-group.com/hs-fs/hubfs/Vignette%20blog%20Hubspot%20(22).png?width=1200&length=1200&name=Vignette%20blog%20Hubspot%20(22).png)   ## Modernisation: obsolete PLC retrofit Retrofitting of a traditional source changeover relay with the automatism integrated in the protection relay, an example with SEPAM. ![obsolete PLC retrofit](https://info.comeca-group.com/hs-fs/hubfs/Vignette%20blog%20Hubspot%20(23).png?width=1200&length=1200&name=Vignette%20blog%20Hubspot%20(23).png)   A project underway or coming up? ➡️ Connect with our experts:     Tags: [Maintenance & services](https://blog.comeca-group.com/en/tag/maintenance-services), [Technical ressource](https://blog.comeca-group.com/en/tag/technical-ressource) [Back to Blog](https://blog.comeca-group.com/en) - [Tweet](https://twitter.com/share) ## Related Articles ## [Allhydre MOB vs PRO: Which Solution to Choose for Your Industrial Needs?](https://blog.comeca-group.com/en/allhydre-mob-vs-pro-quelle-solution-choisir-pour-vos-besoins-industriels?hsLang=en) In this article, we will compare the power rectifiers from Comeca's Allhydre range: Allhydre...
