## Summary description

ENSTO SDI27.61 is an arc fault protection device designed to detect and interrupt electrical arcs in low-voltage installations. The unit monitors arc signatures and triggers disconnection to reduce fire risk and equipment damage. It is used in industrial, commercial and residential distribution boards where enhanced arc detection and fast isolation are required.

## Long description

ENSTO SDI27.61 is an arc fault protection device designed for detection and interruption of electrical arcs in low-voltage installations. The unit continuously monitors electrical signatures to recognise dangerous arc conditions and initiates rapid disconnection to reduce the risk of fire and limit damage to cables and connected equipment. The device is intended for installation in distribution boards in industrial, commercial and residential environments where improved arc detection and fast isolation are required.
Advantages
The ENSTO SDI27.61 provides automatic arc detection that operates independently of standard overcurrent protection, enabling faster response to arc faults. Its monitoring capability reduces the likelihood of sustained arcing events and supports safer operation of low-voltage distribution systems. The compact form factor and compatibility with typical distribution board layouts simplify integration without requiring major changes to existing panels.
Suitable for
Industrial distribution boards with sensitive equipment and production lines
Commercial buildings such as offices, shops and public facilities
Residential apartment blocks and single‑family homes for enhanced fire safety
Renovation projects where improved arc fault protection is being added to existing installations
Key specifications
Function: arc fault detection and rapid disconnection in low-voltage installations
