Voltage Requirements: Range (50/60HZ ±5%) – 190-500V AC, 460-600V AC, Min Voltage – 156V AC, 390V AC, Max Voltage – 550V AC, 660V AC, Catalog Number, PCPU, PCP575. Power Consumption: Less than 40VA. Phase Reversal (Sequence) of thw three phases is anything other than A-B-C. It will not wrok on C-B-A. Response Times: Power Up & Restart After Fault: 1 second fixed, Drop-out Due to Phase Reversal: 100ms fixed, Output Contacts: SPDT 10A @ 277V AC / 7A @ 30V DC; 1 HP @ 250V AC, 1/2HP @ 125V AC, C300 Pilot Duty. Life: Mechanical: 10,000,000 operations; Full Load: 100,000 operations. Temperature: Operating: -28° to 65°C (-18° to 149°F), Storage: -40° to 85°C (-40° to 185°F), Mounting: Uses an 8 pin octal socket. Requires a 600V-rated socket when used on system voltages greater than 300V such as Macromatic Catalog Number 70169-D. Reset: Automatic upon correction of fault.
