Sizes and Ratings

The Toshiba TE Series starters are current rated controllers. Max. Amp
ratings are for continuous duty and must not be exceeded. Always check
the motor nameplate FLA and Service Factor to ensure proper sizing.
Each size has an adjustable current range from 50% to 100% of the Max
Amp rating. Table 1.2 shows the Current Ratings available.
1.2.1
Many NEMA design motors include a design rating referred to
Current
as Service Factor (SF) that may allow continuous operation
Range
above the nameplate current rating. If using this Service
Factor, the TE Series starter must be sized for the total amps
Min.- Max.
used. For proper selection of the TE Series starter when using
SF continuously, multiply the nameplate FLA by the stated
9 - 18
Service Factor, or use stated Service Factor Amps (SFA) if
14 - 28
listed on the nameplate. The following excerpt is from the
19 - 39
NEMA MG-1 standards for AC Motors that describes the
issues concerning the use of Service Factor ratings.
24 - 48
36 - 62
"When an induction motor is operated at any service factor
39 - 78
greater than 1.0, it may have efficiency, power factor and
speed different than those at rated load. Locked rotor torque
46 - 92
and current and breakdown torque will remain the same. A
56 - 112
motor operating continuously at any service factor greater than
1.0 will have a reduced life expectancy compared to operating
75 - 150
at its nameplate horsepower."
80 - 160
105 - 210
When using this feature, simply program the TE Series
Service Factor (F002) to the nameplate rating.(See section
138 - 275
5.6.1.) All other adjustments to the protection circuits are done
181– 361
automatically within the TE Series.
225 – 450
1.2.2
275 – 550
If you need to be able to start the motor Across-the-Line when
the TE Series electronics are out of service, the starter can
300 - 600
also be selected based upon the rating of the Bypass
431 - 862
Contactor. Some users may also elect to size their Bypass
Contactors per NEMA guidelines. When doing this, please
450 - 900
refer to the Product Selection Guide for details and notes, and
503 - 1006
see Appendix 4 for special considerations regarding Overload
Protection.
625 - 1250
1.2.3 The TE...-BP Series starters include the ability to connect a
dry contact directly to the Bypass Contactor coil control circuit. These
terminals are covered when shipped and should be used ONLY
when necessary for Emergency Bypass operation and with an
external Overload Relay. See Appendix 4 for additional information.
No field wiring to these terminals is necessary if this feature is not
used.
