Description

The PGR-6150 Motor Protection System provides 13 protective

functions by utilizing both current and temperature inputs. It is

a modular system consisting of the control unit and an operator

interface (PGR-6150-OPI). The OPI allows programming and

displays metered values. The PGR-6150 is used to provide

current- and temperature-based protection, metering and data

logging for three-phase motors used in industrial environments.

Current transformers are not required for currents up to 25 A.

Features IEEE # BENEFITS

No CTs required 49, 51 No current transformers are required for currents < 25 A

Adjustable trip settings Adjustable overload trip class setting from 5 to 45 to match motor characteristics

Digital input Programmable digital input

Output contacts Two programmable Form C output contacts for operation of separate annunciation and trip circuits

Overload 49, 51 Extends motor life and prevents insulation failures and fires

Overcurrent/Jam 50, 51 Detects catastrophic failures and fires; extends motor life

Undercurrent 37 Detects low level or no-load conditions

Unbalance (current) 46 Prevents overheating due to unbalanced phases

Phase loss/Phase sequence 46 Detects unhealthy supply conditions

PTC overtemperature 49 Detect high ambient or blocked ventilation and single phasing; prevents shaft/pump damage

Dynamic thermal model Provides protection through starting, running, overload, and cooling cycles

Communications RS-485 communications to remotely display metered values
