Product Introduction
ABB MT‑91‑ARCFPA is a DIN‑rail mount industrial protection and control module designed to detect arc faults and interrupt hazardous electrical conditions in final circuits. Installed in distribution or automation cabinets, the MT‑91‑ARCFPA combines arc fault detection with a Type B miniature circuit breaker function at 16 A and 230 V AC. It continuously monitors waveform signatures to identify series and parallel arc faults that standard overcurrent devices cannot detect.
The MT‑91‑ARCFPA is built to IEC protection standards (IEC 62606, IEC 61009‑1) and integrates into existing ABB panel layouts on standard 35 mm DIN rail hardware. LED status indicators help with diagnostics and maintenance. Verify exact product variant and RCD integration status with the ABB datasheet, as suffix designators like “‑ARCFPA” can denote specific internal configurations.
