SEL-734 Meter Forms and Models
This instruction manual covers the following SEL-734 Meter Forms and
Models.
Model numbers are derived from the SEL-734 Model Option Table. For the
available options, associated option codes, or to order an SEL-734, refer to the
Model Option Table for this product at the SEL website.
The SEL-734 offers two options for current classes, CL10 or CL20. The
internal hardware of the SEL-734 is identical for both classes. Therefore, a
CL10 meter will meter accurately up to the CL20 meter rating of 20 amps.
The only difference between an SEL-734 CL10 and CL20 is the configuration
label on the front panel. SEL recommends using a CL20 meter unless a
specification calls for a CL10 meter.
Throughout this manual, meter model 0734ES2-6X (Expansion Slot #2 = 6X)
and model 0734ES2-8X (Expansion Slot #2 = 8X) are used to show the
difference from model 0734ES2-XX (Expansion Slot #2 = XX) when
necessary for discussion. The only difference is that meter models
0734ES2-6X and 0734ES2-8X have an extra I/O board (see Figure 2.6).
Meter models 0734ES1-XX and 0734ES1-2X show the difference between an
empty expansion slot #1 and slot #1 with an optional communications card.
