MOTOR PROTECTOR

Klixon® Snap-Action Controls

Introduction

Design and Operating Principles

Serving the Customer

The Klixon® disc is made of a combination of different metals with

a predetermined calibration point. When heated, one of the metals

expands more than the other, causing the disc to snap. As a world leader

in bimetal technology and bimetal-based devices, Sensata Technologies

has set its goals of constant improvement and maximum reliability

during years of operation and thousands of cycles. These high quality

standards also explain the impressive production of several hundreds of

millions of Sensata Klixon® controls annually.

As a world leader in automotive motor protection, Sensata Technologies has developed the 6AP to operate in wide temperature and current ranges,

while providing consistent performance characteristics and excellent reliability. CAD-based design techniques combined with 6-Sigma supported

manufacturing lines and the best quality control systems give this product maximum safety and reliability. The 6AP operates as a sensitive power cut-

out which is widely used in Window-Lifts, Adjuster-Motors, Wipers, Door-Locks and various other applications. One protector series covers a broad

range of applications, thus providing the flexibility to customize a particular rating based on the specific requirements of universal applications.

The 6AP is manufactured on fully automatic equipment, custom-designed to meet the various requirements of today’s automotive industry. The compact 6AP

metal housing with integrated terminal holds the pre-set Klixon® snap-action bimetal disc. The split plate carries a resistive S-shaped wire which provides

additional current sensitivity. The advanced contact system - one on the bimetal disc and one on the plate - in combination with the strong disc guarantees a

long life and reliable cycling. The operating principle of the 6AP is both simple and effective. The protector is actuated by current passing through and by heat

received from the ambient temperature. The electrical circuit is interrupted when the disc reaches its preset temperature. As the device cools down to a safe

temperature again, the contacts automatically reset. Each 6AP temperature rating has a bimetal disc specifically manufactured for that rating. Each device is

calibrated and checked for opening-temperature. This results in optimum characteristics and consistent performance over the required life.

Just provide us with your specifications concerning specific current and temperature rise conditions and we will select a matching 6AP motor protector and

provide you with samples. But we do more than that. A skilled staff is available to perform application testing and protector selection in a well-equipped

laboratory with sophisticated, state-of-the-art equipment. In close cooperation with the customer we develop the optimum solution, providing the lowest cost

of ownership and thus increasing your competitive advantage. If motor testing and assembly are required on a larger scale, pilot series for your verification will

be supplied within a very short cycle time. With design cycles becoming shorter and shorter, you can expect our prompt reply. If you wish to select your own

ratings we have a software tool available to assist you in making the right selection.
