DPA51CM44B014 CARLO GAVAZZI Phase Monitoring Relay

• Voltage Input Range: 208 to 480 V AC (covers 3-phase mains systems from 177 V AC up to 552 V AC with a ±15% tolerance).
• Output Configuration: 1 Single Pole Double Throw (SPDT) relay, normally energized.
• Current Contact Rating: 5 Amps switching maximum.
• Frequency Range: 50 to 60 Hz.
• Housing Profile: 17.5 mm ultra-compact width for space-saving DIN-rail mounting.
• Safety & Certifications: UL, CSA, and CE compliant.
• Phase Sequence Protection: Prevents three-phase motors from starting or running in the reverse rotation, which can quickly cause catastrophic mechanical failures in HVAC compressors, industrial conveyors, and pumps.
• Phase Loss Monitoring: Automatically disconnects the load if any individual phase drops out, avoiding motor overheating and rapid torque reduction.
• Regenerated Voltage Detection: Safely triggers a fault response even if a failing motor attempts to reconstruct a missing phase voltage up to 85% of the nominal grid value.
• Plug-and-Play System: Operates on an automatic setup profile requiring no manual setting adjustments or external calibration. Dual LED bulbs give instant visual diagnostics for "Power Supply On" and "Relay Status".
• Logistics Note: The suffix variation "B014" is a specific packaging or manufacturing batch suffix often designated on units distributed directly from factory assembly facilities in Europe and Asia. It remains fundamentally interchangeable with the standard catalog identifier DPA51CM44.
