GE Multilin MMII-PD-1-2-240 Intelligent Motor Management and Protection Device

GE Multilin MMII-PD-1-2-240 Intelligent Motor Management and Protection Device

GE MMII-PD-1-2-240 is an intelligent motor management and protection device of GE Multilin Motor Manager II (MMII) series, compatible with 240VAC auxiliary power supply version, installed in the MCC drawer unit of the low-voltage motor control center. The MMII-PD-1-2-240 motor management and protection device integrates motor protection, start stop control, power monitoring, fault recording, and communication upload. It relies on CT to collect motor three-phase current and ground fault current, and has a built-in thermal model to simulate motor heating, achieving protection tripping such as overload, locked rotor, phase loss, current imbalance, and ground fault; MMII-PD-1-2-240 can simultaneously support local panel operation, remote start stop, and upload operating parameters and fault events to the DCS/SCADA system. It is a comprehensive protection and measurement unit for low-voltage high-power motor circuits.

Product Features

1. Integrated motor protection and measurement, built-in heat accumulation model, accurately simulating motor winding heating, suitable for frequent motor start-up.
2. Rich protection logic: blocking, phase loss, three-phase imbalance, ground fault, overload, undercurrent, etc., all protection thresholds are programmable.
3.  Optoelectronic isolation digital input circuit, resistant to strong electromagnetic interference on site, suitable for MCC cabinet environments with dense frequency converters and contactors.
4.  Comes with a built-in LCD panel and buttons for local start stop, parameter setting, current viewing, and fault codes, without the need for a computer.
5.  Support Modbus communication, real-time upload of current, power, thermal capacity, and fault records to the upper monitoring system.
6.  Trip events and waveform storage before tripping, facilitating post fault traceability analysis and reducing downtime for troubleshooting.
7.  Two 4-20mA analog outputs can be used to send signals such as current and thermal capacity to DCS analog cards.
8.  Standard MCC drawer panel installation structure, directly replacing the old MMII series protection device, with strong universality of spare parts for existing projects.
9.  Independent emergency stop button to meet local emergency stop safety requirements on site.
