Frequently Asked Questions about 169PLUS-100P-120
What is the 169PLUS-100P-120?
General Electric Multilin’s 169PLUS-100P-120 is a microcomputer-based device that offers accurate, holistic protection for three phase motor systems. The relay is able to learn unique system parameters and adapt to measured conditions over time.
What features are specified by a GE Multilin 169PLUS-100P-120 motor management relay of the Multilin 169 PLUS relay series?
The Multilin 169PLUS-100P-120 is a member of the Multilin 169 Plus family of management relays that are designed to provide protection for motors to ensure that they are performing well in light of variable load, supply, or operating conditions. Some features included in modern motor protection are rotor and stator thermal modeling, as an increase in thermal conditions can be detrimental for the motor’s performance. Thus a motor protection system, such as members of the GE Multilin 169 or 169 Plus is beneficial for the end user. The 169PLUS-100P-120 affords the user with stator RTD readings of temperature in order to create a model that is used to provide motor protection. The cooling time of the motor is also considered for this end goal. The 169PLUS-100P-120 is able to be programmed to allow for tailored motor protection to an individual motor. One 169PLUS-100P-120 is necessary to protect a given motor. Like other GE Multilin 169PLUS motor protection relays, the 169PLUS-100P-120 is able to monitor both phase and ground fault currents so that motors can be protected regardless of their specific line voltage. The 169PLUS-100P-120 has the order codes 100P and 120 found within the part number. These specifications are variable among each 169 or 169 Plus Multilin relay, and indicate the type of RTD sensor and control voltage that the relay is characterized by. In this case, the 169PLUS-100P-120 has a 100 ohm platinum RTD sensor and a 120 AC control voltage
