| Rated voltage | 100/110, 200/230 VAC | ||||
| Frequency | 50/60 Hz (See note 1.) | ||||
| Input signal for control | External main setting (See note 2.) | 2 kΩ (type B, 2 W min.) | 3 kΩ (type B, 2 W min.) | 2 kΩ (type B, 2 W min.) | |
| Current input | 4 to 20 mA (at 1 to 5 VDC) (Input impedance: 250Ω) (See note 3.) | ||||
| Voltage ON/ OFF input | 5 to 24 VDC (Input impedance: approx. 20 kΩ) | ||||
| External duty setting | 3 kΩ (type B) | ||||
| Relay output for alarm | --- | SPDT: 8 A at 250 VAC/30 VDC | |||
Note:
1. 50 ⁄ 60 Hz (no selector required) (EUN Series) Terminals 18 and 19 of EHN ⁄ EC-series models must be open when the supply frequency is 50 Hz. These terminals must be shortcircuited when the supply frequency is 60 Hz.
2. Use the G32X-V2K 2-kΩ Variable Resistor for external main setting on EUN, EC, and EHN (G32X-V3K 3-kΩ for EN-series models).
3. Input 4 to 20 mA or 1 to 5 VDC linear input to the 4 to 20 mA current input terminal.
Output
| Model | Applicable load | |||
| Rated load voltage | Load current | Inrush current | Number of phases | |
| G3PX-220E[] G3PX-220E[]N | 100/110, 200/220 VAC (50/60 Hz) | 1 to 20 A (at 40°C) (See note.) | 220 A (60 Hz, 1 cycle) | Single |
| G3PX-240E[] G3PX-240E[]N | 1 to 40 A (at 40°C) (See note.) | 440 A (60 Hz, 1 cycle) | ||
| G3PX-260E[] G3PX-260E[]N | 1 to 60 A (at 40°C) (See note.) | 440 A (60 Hz, 1 cycle) | ||
Note: The G3PX-2[][]EHN (model with multiple heater open circuit detecting function) and G3PX-2[][]EC (constant-current model) require 20%min. of the rated current to detect a short mode failure. EC-series models detect an open mode failure if the load current has dropped to 80% of the rated value. A short mode failure will be detected if the current has risen to 20% of the rated value.

Note:
1. Duty setting does not complete to the OFF state (i.e. 10% remains).
2. The start-up time is factory-set to 1 s on the EH Series, approx. 0.5 s on the EHN and EC Series.
3. This is the initial start-up time with a 100% duty setting.
4. Detection is effective when the set current is reduced by 20% or more.
5. The minimum set value in the G3PX-220EHN is 6 A. If a lower value is required, increase the number of wiring turns around the CT.
