ABB
TYPE: REA101-CAA
ARC PROTECTION RELAY
REV: B
REF.NO: FKM3280
The ABB REA101-CAA is an arc protection relay designed to detect and respond to arc flash events within electrical switchgear systems. In marine and offshore environments, arc flash incidents represent one of the most dangerous electrical hazards, capable of causing severe equipment damage and risk to personnel. This relay provides rapid arc fault detection and trip signalling, enabling switchgear protection systems to isolate faults within milliseconds, safeguarding critical power distribution infrastructure onboard vessels and platforms.
