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

PGB-6130 Remote Indication

and Reset Assembly
