Product description

The 269-120N-120VAC is a Multilin series of motor management relays manufactured by GE. The 269-120N120VAC is designed to monitor, protect and control medium sized AC motors.

The relay is capable of data logging, current and heat capacity metering, temperature monitoring, and voltage and power metering (with the addition of an optional MPM (Motor protection meter).

The 269-120N-120VAC features include:

120 ohms nickel RTD

Microprocessor-based technology

The motor is turned off when the thermal limit is exceeded

Can detect potentially destructive or dangerous situations

Latch the main trip relay, alarm relay and emergency restart

User programming is possible on site. The keyboard and interface provide end users with local programming and data viewing options. While the 269-120N-120VAC is pre-programmed for basic applications, end users can make subtle changes to meet their needs.

The help key. On the front panel, you can always access this feature for more information.

Easy to read interface. 48-character LCD backlight for easy viewing. 5 LED status indicators update user output relay operation and self-check alarms.

The 269-120N-120VAC housing is IP40X compliant, corrosion resistant and flame retardant. 269-120N-120VAC should be installed using 4 washers and 4 10-32 x 3/8 "screws by pre-drilling. It is recommended to place the relay away from strong magnetic fields that can cause noise picking and interference.

269-120N-120VAC Rated voltage is 250VAC 15A resistor, 1/4HP 125 VAC, 1/2 HP 250VAC. The maximum input is 80-150 VAC/VDC 2A. The frequency is 50/60 Hz or DC. The overpressure category is II. The pollution level is 2.
