Product Description

The 139-DO-FLC Motor Protection Relay is one of the relays with a different output option than the standard option; the output associated with this mode is a full load current, which is denoted by the FLC acronym at the end of the part number, operates on a milliamperage of four to twenty. The D in the order code indicates what type of supply power is needed to operate this relay without any faults occurring. The power supply for this model is one hundred and twenty volts of alternating current.  

One feature of this relay is the start timer. The start timer on this model is used with an induction motor which draws an inrush current while moving up to the desired speed for starting which is usually greater than the full load current. When starting the timer across the line the range is typically between five and seven times the standard running current. When setting the start timer it is best that the true run-up time is measured and then specified by the locked rotor times as well as the continuous number of starts allowed by the manufacturer. It is best to set the control of the start timer on the 139-DO-FLC relay to a timer that will be less than the max locked rotor time but is still greater than the overall time needed for the max number of back-to-back starts allowed. 

Memory lockout is another feature used with the 139-DO-FLC relay. There are several start conditions that can trip memory lockout, these conditions are overload and start trip conditions. For more information on the memory and memory lockout of this device refer to the attached manual.

What are the control power specifications for the 139-DO-FLC Multilin GE motor protection relay?
The 139-DO-FLC has a standard control power of 120/240 VAC with an optional 125 VDC potential. The Power is specified at 5 VA with a frequency of 50 to 60 Hz. The 120VAC input ranges from 90 to 150 VAC. The 240 VAC input range for the 139-DO-FLC Multilin GE motor protection relay is from 176 to 270 VAC and the 125 VDC input range is from 80 to 150 VDC. 
What are the external relay connections of the 139-DO-FLC Multilin GE motor protection relay?
The 139-DO-FLC Multilin GE motor protection relay has three phase current CT inputs (phase 1, phase 2, phase 3). Additionally, the 139-DO-FLC or a 139 Multilin motor protection relay may include a ground fault current CT. This is optional to the base unit. Other features optional to a 139 Multiin is a RTD temperature sensory, an external reset switch, and an emergency restart key switch.
What are the standard outputs for a 139-DO-FLC Multilin GE motor protection relay?
The standard outputs for a 139-DO-FLC Multilin GE motor protection relay are a contactor/breaker trip (main relay contacts) and an alarm (Aux relay contacts). Optional to the base unit is a analog temperature output, a thermal capacity used meter, or a 4-20mA output of the full load current (FLC option). 

Reviews For 139-DO-FLC

(5.0)

One feature that makes this relay a great purchase is that if at any point the control power for this model has been removed, the memory on the device will remain active and continue to discharge at a rate proportional to an idling motor. - AX Control Technician
