2MM
Motor Protector/Thermal Cut-Out
KEY BENEFITS
Field proven reliable and repeatable
snap-action bimetal actuation.
Low profile shape for close coupling to
on- or in-winding application.
On customers request additional
sleeve available.
Competitive performance-price ratio
Sensata Technologies builds the
2MM motor protector to meet almost
any requirement of protection in a
wide range of small motors, small
transformers, solenoids, etc..
This compact motor protector is the
best solution to protect the wide
variety of motors used in industrial
and domestic appliances against
locked rotor and overload situations.
Design and operating principles
The motor protector 2MM consists of
a metal housing that holds and pro-
tects the inner components against
infiltration as well as mechanical
deformation.
The can contains the calibrated
Klixon® disc carrying a silver con-
tact. The fixed contact is placed on
the opposite side, separated from
the terminal by an insulator.
The 2MM is available in two ver-
sions: with epoxy insulation and with
additional sleeve.
The operating principle of the 2MM
is both simple and effective. A cur-
rent flows through the resistive
Klixon® bimetal disc. When a fault
condition occurs, the increased cur-
rent and ambient temperature make
the bimetal disc snap open the con-
tacts. The contacts close again auto-
matically as the device cools down
to a safe running temperature.
Applications
The 2MM operates as a sensitive
safety cut-out for applications like:
· Small motors
· Coils
· Solenoid valves
· Transformers
In single phase motors it can be
mounted directly in the main circuit
to serve as on- or in-winding protec-
tor. It's compact size provides ease
of installation, even in small spaces.
At this time there is practically no
small motor the 2MM cannot protect
against overheating and overload-
ing. Sensata Technologies 2MM pro-
vides you with a cost effective solu-
tion in terms of maximum quality
and reliability.
