Short DescriptionTHREE PHASE MONITORING RELAY 380-415VAC
Long DescriptionThe ALLEN-BRADLEY 813S-V3-400V is a 3-phase voltage monitoring relay that protects electrical systems by detecting under- and overvoltage conditions across 380–415V AC supplies. This self-powered relay monitors phase loss, imbalance and reversal, and includes adjustable time delay and two SPDT contacts for direct control or alarm signaling. It supports 50–400 Hz operation and offers programmable latch or inhibit behavior at the set level plus an auto-reset option to resume normal operation after faults clear. Suited for motor control panels, distribution boards and industrial equipment, it helps technicians and maintenance teams prevent downtime and manage phase-related faults.
