Space Heaters - MOD12, and MOD41
(Mult. Symbol S4)
Space heaters are used to prevent the build-up of condensation on the
windings of the motor when the motor is not operating. Space heaters are
typically installed on the end-turns of the coils.
Space Heaters - ODP & TEFC - MOD12
Space heaters can be furnished on Drip proof and totally enclosed motors.
Heater leads are normally brought out to the motor conduit box. Heater
voltage is available in three voltages for 60 Hz operation of 115, 230, or 460
volt, single-phase. Space heaters are sized per NEMA standards.
Lead-time is 2 days.
Space Heaters - IEC Frames - MOD12
Space heaters can be furnished on IEC motors. Heater leads are normally
brought out to the main terminal box. Heater voltage is available in two
voltages for 50 Hz operation.
Lead-time is 2 days.
Space Heaters - Explosion Proof - MOD41
Space heaters can be furnished on explosion proof motors. Heater leads are
normally brought out to the motor conduit box. Heater voltage is available
in three voltages for 60 Hz operation of 115, 230, or 460 volt, single-phase.
Space heaters are sized per NEMA standards.
Lead-time is 2 days.
Terminal Blocks - MOD0 (Mult. Symbol S4)
Conduit box mounted terminal blocks provide for a convenient termination
of power leads. The terminal blocks are sized for the proper amperage and
voltage of the motor. The Globetrotter
®
IEC motor has IEC terminal blocks as
standard.
Terminal Block
Install terminal blocks in conduit box of NEMA motor with lead connection.
Customer to advise on lead connection. Call for lead-time. Contact factory to
verify capability.
Thermal Protection - MOD0, and MOD14
(Mult. Symbol S4)
Thermal protection are built in protective devices that prevent motor
overheating. They work either by interrupting the power supply when
the motor overheats or by incorporating a pilot device that opens the
holding circuit of a magnetic starter or energizes an alarm bell or warning
light.
Thermostats - All Motors - MOD14
Thermostats are mounted on the stator winding and are temperature-sensing
only, with normally closed snap action contacts. These devices are installed
on the end-turns of the motor winding. Their purpose is to activate a warning
device or shut down the motor upon excessive winding temperatures. The
standard arrangement is the addition of 2 or 3 thermostats to the winding
end-turns, connected in series with the leads brought out to the main motor
conduit box. Class I Groups C & D / Class II Groups F & G Explosion Proof motors
have hermetically sealed thermostats as standard.
Lead-time is 2 days.
Thermistors - All Motors - MOD14
Thermistors are small, non-linear resistance devices placed on the stator
windings. As the critical temperature is reached, the resistance of the
thermistor changes radically, causing operation of a control relay. The
standard arrangement is Q-3 positive temperature coefficient (PTC) type on
winding end-turns with leads brought out to the main motor conduit box.
On IEC motors the leads are brought into a condulet adjacent to the main
conduit box and includes a terminal block. As standard, 3 Texas Instrument
thermistors are furnished, one per phase. Control Module is available.
Lead-time is 2 days.
Thermocouples - Non XP Motors - MOD0
Thermocouples sense temperature and offer inherent protection against
abnormal stall and running conditions. The standard arrangement is the
addition of an iron constantan thermocouple to the winding end turns or
bearing housing with leads brought out to the main motor conduit box.
Customer must specify number, type, and location at time of order.
Lead-time is 2 days.
Weatherproofing/Special Service
MOD5, and MOD49
(Mult. Symbol S4)
Weatherproofing or special service provides additional protection to windings
and mechanical parts as well as special greases or modifications per industry
specifications such as NEMA, or IEEE. Call for lead-time.
Tropical Anti-Fungus Treatment - MOD5
Windings and mechanical parts coated with polyurethane for superior
protection to resist tropical environments. Not available on brake motors.
Lead-time is 2 days.
Hazardous Duty™ Service
Division 2 Hazardous Motors - MOD49
The Division 2 hazardous modification incorporates a new fan, fan guard, and
nameplate on most TEFC motors. XRI
®
-SD and IEEE841 motors have Division
2 statement on the nameplate as standard. The nameplate will say “CSA
certified, Group I, Division 2, Groups A, B, C, and D, Temperature Code.
