Arc Flash Monitoring Systems

Detect in milliseconds. Protect what matters most.

Arc Flash Monitoring Systems

Mors Smitt arc flash monitoring systems provide high speed optical detection and clearance of arcing faults on busbars and within metal clad switchgear. With trip times under 10 ms using arc detection only, they significantly outperform traditional overcurrent protection, reducing damage and improving personnel safety.

Compact arc flash monitor with up to three sensor inputs and high speed tripping for detection and clearance in retrofit applications.
1S23
Compact arc flash interface module for detection and clearance with IEC61850 GOOSE messaging and continuous sensor supervision.
1S24
Advanced multi-zone arc flash monitor for detection and clearance with up to 16 sensors, Ethernet and IEC61850 communication.
1S25
Four zone arc flash monitor for detection and clearance with nine high speed trip outputs and built-in self-supervision.
1S26
Four zone arc flash monitor with integrated overcurrent check for secure detection and clearance within 15 ms on bus and feeder circuits.
Delta 1S27
