Dongguan Eidoll Elect. Ltd. is sales the Sensata YS11 series. The Specification as bellow:

Features YS11 was developed to protect people and property from accidents or failures that can occur in motors used in fans and washing machines as well as other appliances. It functions as a self-resetting thermal cut-out (Type 2B), thermal motor protector (Type 3C) and thermal protector for ballasts.

The YS11 can be used for on-winding and outside of resin packed motors by clamping or insertion. Since the YS11 has a plastic case, it does not need to be insulated from metal part of the motor.

SPECIFICATIONS

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 can 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 depends on the operation temperature of YS11 protector, each rating should be selected properly.

Application Notes

R-type case was developed for Resin Packed Motor and was designed to resist high pressure which may be applied during molding process. Maximum pressure is required to be control within 7.5Mpa. Please note that R-type case does not have enough sealing capability, therefore it should not be applied for winding varnish process. Dimension is 6.0mm x 7.8mm (ellipse) x 23.0mm length. Used with the S-Type Case 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 should be selected properly to protect Motors and other equipment. Short time trip current and time is described in “Performance” page which helps to choose most adequate operating temperature. Must hold current is also one of important performances, it can be selected from UTC performance curve as well.
