STYLE CHART
BE3-GPR relays are identified by a combination of letters and numbers that make up the style number
and define the electrical characteristics and operational features. The model number, together with the
style number, describe the options included in a specific device and appear on a relay side panel.
Upon receipt of a relay, be sure to check the style number against the requisition and the packing list to
ensure that they agree.
Figure 1-2 is the style number identification chart and defines the electrical characteristics and operational
features included in BE3-GPR relays. In this example, a BE3-GPR P2BVSF is specified and has the
following features:
P - Paralleled generator protection
2 - Neutral ground fault protection
B- Phase balance
V - Reactive current
S - Sync check function
F - Semi-flush mounting
