| Life |
Mechanical: 10,000,000 operations, Full Load: 100,000 operations |
| Load (Burden) |
Less than 3VA |
| Mounting |
Uses an 8 pin octal socket. Requires a 600V-rated socket when used on system voltages greater than 300V (Macromatic Product Number 70169-D--see Page 16 of Catalog). |
| Output Contacts |
SPDT: 10A Resistive @ 240V AC/30V DC, 1/2HP @ 120/240V AC |
| Overvoltage |
Fixed at 110% of nominal voltage. Unit trips when the average of all three lines is greater than the fixed set point for a period longer than the time delay drop-out. |
| Phase Loss |
Unit trips on loss of any Phase A, B or C. |
| Phase Reversal |
Unit trips if rotation (sequence) of the three phases is anything other than A-B-C |
| Phase Unbalance |
Adjustable from 2 - 10% unbalance. Unit trips when any one of the three lines deviates from the average of all three lines by more than the adjusted set point . There is also a 'Disable' setting adjustment that will turn off the Phase Unbalance Protection |
| Reset |
As standard, reset is automatic upon correction of fault. When a momentary-contact N.C. switch is wired across the Manual Reset terminals (6 & 7), the unit switches to manual reset mode and remote manual reset is available. |
| Response Times |

| Temperature |
-28° to 65°C (-20° to 150°F) |
| Transient Protection |
n/a |
| Undervoltage |
Adjustable from 80-95% of nominal voltage. Unit trips when the average of all three lines is less than the adjusted set point for a period longer than the adjustable time delay drop-out. |
