What's the difference between N/C and N/O
Normally Closed: When the temperature falls to the reset temperature, the
thermostat contact can be connected again. (If the reset
temperature is not reached, the thermostat contact is also
disconnected)
Normally Open: When the temperature falls to the reset temperature, the
thermostat contact can be disconnected again. (If the reset
temperature is not reached, the thermostat contact is also
connected)

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.
