Obsolete 05/26/2016. 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.
- No CTs required
- Adjustable trip settings
- Digital input
- Output contacts
- Overload
- Overcurrent/Jam
- Undercurrent
- Unbalance (current)
- Phase loss/Phase sequence
- PTC overtemperature
- No current transformers are required for currents < 25 A
- Adjustable overload trip class setting from 5 to 45 to match motor characteristics
- Programmable digital input
- Two programmable Form C output contacts for operation of separate annunciation and trip circuits
- Extends motor life and prevents insulation failures and fires
- Detects catastrophic failures and fires; extends motor life
- Detects low level or no-load conditions
- Prevents overheating due to unbalanced phases
- Detects unhealthy supply conditions
- Detect high ambient or blocked ventilation and single phasing; prevents shaft/pump damage
