ABB CM-PVE 185-265VAC Three-Phase Monitoring Relay (CM Series)

• Phase Loss Monitoring: Protects downstream equipment (such as three-phase motors) from running on a missing phase, which causes severe overheating and immediate winding damage.
• Overvoltage & Undervoltage Protection: Monitors the mains voltage to ensure it stays within a safe, fixed window. If the voltage swings outside the nominal thresholds, it trips to prevent insulation breakdown or equipment brownouts.
• Interrupted Neutral Monitoring: Ensures that single-phase loads tied to the neutral wire are protected from unpredictable voltage fluctuations or floating neutrals.
• Manufacturer: ABB
• Measuring & Supply Voltage: Phase-to-Neutral (L-N):
• Output Configuration: 1 N/O (Normally Open) output contact
• Output Contact Rating: 250 V / 4 A (AC-12 resistive load)
• Threshold Adjustments: Fixed (Non-adjustable windows)
• Connection Capacity: Rigid / Flexible: 2x 18-16 AWG
• Tightening Torque: 7.08 in⋅lb (0.8 N⋅m)
