Control relay voltage, phase monitoring, adjustable 1P+N/3P(N) 2 changeover contacts. Control and monitoring relay for undervoltage and overvoltage in single and three-phase networks (1P+N, 3P+N). Monitoring of adjustable undervoltage, overvoltage and asymmetry, phase sequence, phase failure and neutral conductor breakage. Signaling via two changeover contacts and LEDs. Mounting on top hat rail (DIN rail).
