PGR-6130 SeRieS
Electronic Overload Relay
Description
The PGR-6130 Electronic Overload Relay provides protection
for small three-phase motors up to 1,000 Vac. No current
transformers are required for currents up to 91 A. The
protective functions include overload, overtemperature, phase
unbalance, phase loss, and phase sequence. The PGR-6130
Electronic Overload Relay offers dependable protection and can
be used on pumps, conveyor belts, ventilation fans and other
small-motor applications that require standard protection.

Ordering Information
NOTE: External CTs can be used for full-load currents >91 A.
FeaTuReS beneFiTS
No CTs required
No current transformers required for currents up to
91 A, simplifies installation and reduces cost
Adjustable
trip settings
Adjustable overload trip class setting from 5 to 35
to match motor characteristics
Output contacts
Form A and Form B ground-fault output contacts for
operation of separate annunciation and trip circuits
Remote indication Allows remote cause-of-trip indication and reset
Overload
Extends motor life and prevents insulation failures
and fires
Phase loss/Phase
sequence
Detects unhealthy supply conditions
Unbalance (current) Prevents overheating due to unbalanced phases
PTC overtemperature
Detect high ambient or blocked ventilation and
single phasing; prevents shaft/pump damage
Features & Benefits
