When
ordering, specify the length of the lead wires by adding a code to the model number as shown below
.

Note:
The G3PX-2jjEHN (model with multiple heater burnout detecting function) and G3PX-2jjEC (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
