ARC GUARD SYSTEM

ABB’s TVOC Arc Guard System stands at the forefront of
electrical safety solutions, specifically tailored for industrial and
commercial environments.

The Arc Guard system employs susceptible sensors to swiftly
detect characteristic signatures of electrical arcs, enabling a
rapid response to mitigate potential hazards. Upon detection,
the system orchestrates a controlled shutdown of the affected
circuit, effectively quenching the arc and preventing further
damage to equipment and personnel. Distinguished by a
modular design, the Arc Guard System seamlessly integrates
into existing electrical panels. Advanced features, such as
communication capabilities and adjustable sensitivity settings,
contribute to its adaptability across diverse applications. The
system’s compliance with international standards underscores its
reliability and commitment to safety.

ABB’s Arc Guard System offers insights into arc fault analysis,
aiding in diagnostics and preventative maintenance.
