Schneider Electric launches the Acti9 iCVm40 and Resi9 RCBO, two Residual Current Circuit Breakers with Overcurrent protection (RCBOs) that deliver the same high level of protection as previous models, in half the footprint. The new devices combine the functions of a Residual Current Device (RCD) and a Miniature Circuit Breaker (MCB) into a single, miniaturised solution, reducing device width from 36mm to just 18mm and helping free up valuable space inside electrical panels.
Traditional RCBO installations take up valuable panel space, often requiring the use of larger panels or complete panel replacement during upgrades. This is a significant challenge in retrofit projects, increasing cost and complexity. Schneider’s new Acti9 and Resi9 RCBOs save panel space thanks to their compact 18mm wide design. This enables panel builders to add more protected circuits or create room for additional features, helping them modernize existing installations without expanding panel size or making costly structural changes.
In addition, in RCD + MCB architectures, a single earth leakage fault tripping disconnects all circuits, resulting in unnecessary disruptions. This is particularly damaging in environments with multiple zones where interruptions can be costly and can disrupt business services.
The RCBOs deliver zone‑specific protection, isolating only the impacted circuit and helping to minimize operational downtime. With the new miniaturized format, electricians can replace traditional RCD + MCB setups with the new device without increasing panel size or requiring additional space.
The Acti9 iCVm40 is part of the optimized Acti9 iC40 system and Resi9 system for residential, designed to make panel building easier and more efficient. Both the Acti9 and Resi9 RCBOs are compatible with Schneider Electric’s digital configuration tools, including EcoSet Design, EcoSet Config, Ecoreal, e-Design Small Building, and Caneco, helping streamline electric panels design and implementation.
