About the 169-120N-120

The 169-120N-120 is a Motor Management Relay produced by General Electric Multilin. Capable of protecting, managing, and monitoring motor systems, the 169 relay includes protective features such as ground fault protection, overcurrent protection, and phase reversal. These features save users money in the long run since protective features extend motor life and reduce time spent maintaining the system.

The motor is capable of activating pre-trip alarms that indicate when issues are arising in the system. Each trip (and alarm) has an associated display message so users can easily identify the source of the problem. While only a single trip can occur at any given time, multiple alarms can be activated simultaneously, and these can be activated while a trip is occurring. In the event that multiple alarms are active at once, the 48-character liquid-crystal display will list them in order of priority. Users can navigate the list using the keypad located on the faceplate beneath the LCD.

The 169-120N-120 is highly configurable and offers a wide array of possible connections. For users with minimal system requirements, not every port needs to be utilized by the system; users could potentially get by with simply three phase current CT inputs, supply power, and trip relay contacts. However, users with great configuration needs have countless additional options such as RTD inputs and various CTs.

Frequently Asked Questions about 169-120N-120

What is the 169-120N-120?

General Electric Multilin’s 169-120N-120 is a Motor Management Relay which offers a number of elements that protect, monitor, and manage three phase motor systems.

What are the RTD options for a 169-120N-120 Multilin GE motor management relay of the 169 series?

The RTD option of a 169-120N-120 is specified in the part number as 120N. This order option affords the relay with an RTD input sensor that is composed of 120 ohm nickel. The other possibilities for the RTD sensory are 100 ohm platinum (100P), 10 ohm copper (10C), or 100 ohm nickel (100N). The GE Multilin 169-120N-120 motor management relay is a 169 relay model. The 169 Plus models are equipped with two additional RTD inputs. The maximum lead resistance for the RTD inputs is specified as 25% of the RTD sensory with a resistance condition of 0 degrees C. The display has an accuracy of 2 C (plus/minus) and the dead band of the RTD inputs is 3 C. The RTD inputs have a range from 0 to 200 degrees C in regard to trip and alarm setpoint range.

What are the environmental restrictions for a Multilin 169-120N-120 motor management relay?

The 169-120N-120 Multilin and other motor management relays of the GE Multilin 169 or 169 Plus series of relays have an operating temperatures range that is between negative 10 degrees C and positive 60 degrees C. The range that is displayed during operation however is only between 0 degrees C and positive 55 degrees C. The GE Multilin 169-120N-120 has a control power of 120 VAC. This control power is also specified in the order code designated by the 120 numeric at the terminal end of the part number.
