Dimension & Structure

KSD9700-A is metal case while KSD9700-B is plastic case.

How it works?

KSD9700 series thermal protector consists of dish-shape high sensitive bimetallic elements,

movable contact-head, static contact-piece, soleplate, outer case, heat-resistant leads and so

on.When it is in operation, the bimetallic elements are in a free state and the movable

contact-head and the static contace-piece are closed and the circuit is on.When the electric

appliance malfunctions and causes temperature to rise to the action temperature of the thermal

protector, inner stress is produced inside the heated bimetallic elements and the bimetallic

elements act instantly -pushes the movable contact-head away from the static contact-piece,

thus cutting off the faulty circuit and protect the appliance.When the temperature of the electric

appliance to be protected drops to the rated reset temperature, the bimetallic elements restores

to its initial state and contact is closed .The electric appliance restores its working condition.

This product has many advantages, such as low resistance, fast temperature sensing, prompt

action, safety and reliability, small size and so on.

Please Note :

• During installation, the temperature switch should be completely close to the mounting surface of the tested appliance.
• Do not collapse or deform the plastic / metal shell during installation.
• For metal temperature controller, when using, do not remove the insulating sleeve to avoid electric leakage. Not suitable for working in water.
• Not suitable for air temperature sensing, only applies to contact sensing.

Selection of the Fuse and Holder Solution

The first step is to answer the following questions:

• Will the fuse need to accessible for replacement?
• How often will the fuse need to be replaced?
• Should the end customer of the appliance have access to change the fuse?
• Should the fuse only be accessible from outside the appliance?
• How much is available to spend on safety and reliability?

5.1.2. Requirements and characteristics

The most important standards for fuse-holders, which specify requirements, characteristics and testing methods are:

• IEC-publication 257 (1968) and Amendment no. 2 to this publication dated January 1989.
• UL-standard no. 512.

• Company warehouse
