1. Product Title

ABB 1SFA663001R1004 TVOC‑A3 – Arc Guard System Arc Fault Monitor Unit

2. Product Overview

The 1SFA663001R1004 TVOC‑A3 is a compact enclosure‑mount arc‑fault monitoring unit belonging to ABB Arc Guard safety systemARE. It receives optical sensor signals from arc‑fault detectors installed inside switchgear cabinets, detecting dangerous internal electric arcs and triggering fast protective actions to limit equipment damage and personnel hazards. Housed within robust metal field enclosure, it accepts 24‑48 VDC supply and provides status indication plus relay alarm outputs. This safety device mitigates arc‑flash risks within medium‑and‑low‑voltage switchgear and MCC assemblies.
