| Specifications |
| Product Attribute | Attribute Value |
| Type | Reversal, Loss, Unbalance, Voltage |
| Coil Voltage | 240 |
| Contact Configuration | - |
| Mounting | Surface-Mount |
| Contact Current | 10 Amps |
| Hysteresis | 2 - 3% |
| Indicator LED | See Datasheet |
| Life | Mechanical: 10,000,000 operations, Full Load: 100,000 operations |
| Load (burden) | Less than 3VA |
| Mounting | Does not require a socket. Can either be mounted directly on 35mm DIN track with no additional parts or to a back-panel with two screws. |
| Output Contacts | SPDT & SPNC, N.O.: 10A Resistive @ 240V AC/30V DC, 1/2HP @ 240V AC, N.C.: 10A Resistive @ 240V AC/30V DC, 1/3HP @ 240 VAC |
| 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 if nuisance tripping is a problem. |
| Reset | As standard, reset is automatic upon correction of fault. When a momentary-contact N.C. switch is wired across the Manual Reset terminals (5 & 6), the unit switches to manual reset mode and remote manual reset is available. |
| Response Times | See Datasheet |
| 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. |
