Protection Relays & Controls

Generator & Single-Function Protection–Ground Fault

PGR-4300 SERIES (GFA300)

Generator Ground-Fault Relay

Description

The PGR-4300 Generator Ground-Fault Relay provides

a simple method for detecting a ground-fault condition

on generators without the need for current transformers

(CTs). This greatly simpliﬁes the installation. In addition,

it is compatible with both three- and four-pole transfer

switches. This relay also monitors the neutral-to-ground path

for continuity. The PGR-4300 is ideal for any generator or

application where there is not sufﬁcient space to install CTs.
