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.
