GE MMII – PD – MOD501 – 120 is a microprocessor-based motor protection system of the Multilin series by General Electric (GE). The following are some of its parameters:
- Dimensions: Approximately 7.4 inches in length, 4.4 inches in height, and 5 inches in width.
- Weight: 1.36 kilograms.
- Software: Enervista MMII.
- Analog Input Range: 4 – 20mA.
- Operating Temperature Range: 0°C to 60°C.
- Pollution Degree: II.
- Overvoltage Category: II.
- Input and Output Ports: There are a total of 20 I/O ports, among which 4 are output ports (2 contactor outputs and 2 programmable outputs), and 16 are input ports (6 fixed inputs and 10 programmable inputs).
- Monitoring Function: The monitoring display screen can show phase current, ground current, thermal capacity, and analog inputs, and can also record tripping and pre-tripping values for evaluation.
This module has a variety of protection functions, including thermal overload protection, ground fault detection, over-temperature protection, undercurrent and under-power protection, as well as overvoltage protection, etc. It operates through a series of highly versatile settings called “set points”. Users can edit these set points to determine when to trigger tripping and alarms, thus protecting the motor from potential problems such as overload, phase imbalance, contactor or rotor faults, etc.
