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.

Features BENEFITS

No CTs required No current transformers required for currents up to

91 A, simplifies installation and reduces cost

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
