Features
YS11 was developed to protect people and property from accidents
occurring on Motor which is used for Fan motor, washing machine and
so on. It functions as a self- resetting thermal cut-out (Type 2B),
thermal motor protector (Type 3C) and thermal protector for
ballasts.
The YS11 pursued to enable to be used for both of installation
manner of on-winding and outside of resin packed motor by clamping
or insertion. It directly cut off power line. Since it has plastic
case, it does not need to insulate YS11 protector from metal parts
of motor.
Construction
YS11 is constructed with simple design and based on the well known
thermostat technology of Sensata Technologies. And it has enough
sealing capability to withstand varnish process and reinforced case
enabled to be laced on winding.
7.Movable Arm carries current from 1.Lead to 9.Lower Terminal which
is insert molded in 6.Lower Block, via 10.Movable Contact and
Stationary Contact.
7.Movable Arm, 8.Bimetal Disc and 5.Upper Plate are riveted to
secure with 6.Lower Block by 4.Eyelet. This assembly is inserted
into 3.Case, and potting Epoxy to seal.
Since trip time to cut off the power is depending on the operation
temperature of YS11 protector. Rating should be selected properly.
With referring Performance curve, it can be enabled to select best
one which is matching with Motor.
Application Notes
R-type case was developed for Resin Packed Motor. This is designed
to resist for high pressure which may be loaded during molding
process. Maximum pressure is required to be control within 7.5Mpa.
Please be noted that R-type case does not have enough sealing
capability, therefore it should not applied for winding varnish
process. Dimension is 6.0mm x 7.8mm (ellipse) x 23.0mm length.
S-Type Case is for use in higher ambient temperature and same
configuration as standard case. Housing material is used PPS
(RTI:240 °C) which is same as R-type case, so that it can resist
high temperature for short time. This case is not guaranteed for
varnish process as well.
Rating
Rating should be selected as properly to protect Motors and other
equipment. Short time trip current and Time is described in
“Performance” page which helps to choice most adequate operating
temperature. Must hold current is also one of important
performances, it can be selected from UTC performance curve as
well.
Certifications
UL : E15962 for Motor Protector
E34618 for Temp Indicating & Regulating
ENEC : 2014531.17 for thermal cut-out, -motor and-ballast protector
CQC: CQC02002001340/CQC02002001341 -Protectors are not applied in
CCC(China Compulsory Certification) at present. So YS11 can not
have CCC but CQC. CQC(China Quality Certification Centre) is a
national certification body for appliance in China.
