Application Information:
Load (Burden): 10VA (1W) @ 400V / 50Hz; 16VA (1.5W) @ 480V 60Hz. Minimum/Maximum Voltage: 187V AC – 528V AC. Output Contacts: SPDT 5A @ 250V AC. Life: Mechanical – 20,000,000 operations; Electrical – 200,000 operations at 1000 VA resistive load. Temperature: Operating, -25o to 55o C; Storage, -25o to 75o C.
Approvals:
Operations
Phase Loss: Unit trips on loss of any Phase L1, L2 or L3, regardless of any regenerative voltages.
Phase Reversal (Out-of-Sequence): Unit trips if sequence (rotation) of the three phases is anything other than L1-L2-L3. It will not work on L3-L2-L1.
Phase Unbalance: Adjustable from 5 – 25% unbalance or can be disabled. Unit trips when any one of the three lines deviates from the average of all three lines by more than the adjusted set point for a period longer than the adjustable trip delay.
