Product Description

The new Cutler-Hammer

IEC Open

Non-reversing and Reversing Manual

Motor Controllers from Eaton’s electrical

business combine a Manual Motor

Protector with an IEC Contactor(s) to

provide a complete motor protection

solution by combining motor disconnect

function, thermal overload protection,

magnetic short circuit protection and

remote control operation in one com-

pact, assembled unit. These assembled

Manual Motor Controllers cover

motors with FLA ratings from 0.10A to

52A.

The UL 508 Type F labeled Combination

Motor Controller (CMC) includes a Line

Side Adapter (LSA). These assembled

Combination Motor Controllers cover

motors with FLA ratings from 0.10A to

52A.

Application Description

The XT IEC Non-reversing and Revers-

ing Manual and Combination Motor

Controllers can be used in the follow-

ing applications:

XTSC and XTSR

■ Manual Motor Controller for Single

and Multi Motor Panels — The pre-

assembled XT Manual Motor Con-

trollers (MMC) combine a Manual

Motor Protector, a Wiring Connector

Link and IEC Contactor. The XTPR

Manual Motor Protectors are UL

listed as

UL 508, Type E Self-

Protected Manual Combination

Starters. MMCs can also be ﬁeld

installed with separate MMP, WCL

and Contactor(s). An IEC magnetic

contactor has been added to allow

for remote operation of the motor

circuit.

XTFC and XTFR

■ Combination Motor Controller (UL

508, Type F), for Single and Multi

Motor Panels — The preassembled

IEC Combination Motor Controllers

combine a Line Side Adapter, Man-

ual Motor Protector, Wiring Connec-

tor Link and IEC Contactor. The

XTPR Manual Motor Protectors are

UL listed as UL 508, Type E Self-

Protected Manual Combination

Starters. This UL listing allows these

devices to be used in motor circuits

without having to add separate

branch short circuit protection. An

IEC magnetic contactor has been

added to allow for remote operation

of the motor circuit.

■ Group Motor Installations — Since

the Manual Motor Protectors

(Manual Combination Starters) are

UL listed for Group Motor Installa-

tions, the IEC Manual Motor Control-

lers provide a compact, assembled

package for Group Motor Installa-

tions up to 600V.

For Group Installations (in-panel

SCPD) applying the traditional 1/3 tap

rule, the Manual Motor Protectors and

Combination Motor Controllers may

be used on 480V Delta systems along

with 480Y/277V and 600Y/347V slash

rated Wye systems. For Group Installa-

tions, applying the more recent 1/10

tap conductor rule, a maximum 240V

Delta is permitted or 480Y/277V and

600Y/347V slash rated Wye systems.

For actual UL 508 Type E/F applications

(out-of-panel upstream feeder Short-

Circuit Protective Device [SCPD] only),

a maximum 240V Delta is permitted or

480Y/277V and 600Y/347V slash rated

Wye systems.

For Manual “At Motor” Disconnect

applications, a maximum 240V Delta is

permitted or 480Y/277V and 600Y/347V

slash rated Wye systems.
