The picture showed KSD301 Thermostat type is manual reset, normally
closed with electrical rating 250V 16A, PPS Case.
It is open cap for better heat sensitive, used for printer and copy
machine.
1. KSD301 Thermostat Introduction:
KSD301 Thermostat is a small bimetal snap-action thermal protector
with shell. Action principle is that the component bimetal disc
jump at the change of temperature, the contact point can be
closed/opened rapidly to connect/disconnect the circuit.
It has a wide range of temperature, low temperature till high
temperature, can be set according to customer requirements.
Cap/Case material, Bracket type/Terminal Orientation/Terminal Size
could be customized based on actual demand.

Please refer to below KSD301 Thermostat Specification, it includes
some options about bracket/Terminal types and case materials.
We would like to cooperate customer for customization production to
realize what he or she wants.
3. Attentions about KSD301 thermostat installation:
1. During thermostat using process, need to avoid moisture and
pollution, otherwise it will affect the electrical performance of
the product. Recommended thermostat working environment is that
relative humidity ≤90%, no contact with corrosive and flammable
things.
2. During installation, need high attention that the
temperature-sensitive surface should not be deformed, and the top
of the cap should not be collapsed or deformed, so as not to affect
the temperature performance and electrical performance of the
product.
3. During installation, need to make sure the thermostat’s
temperature-sensing surface to be evenly contacted with the
temperature-controlling part, and the force should be evenly
applied to stabilize the temperature-sensing. Besides, need to coat
the surface of temperature-sensitive with thermal grease or other
similar heat-conducting medium.
4. During installation, the terminals should not be bent
vigorously, and the connections between terminal and wire should be
in good contact, otherwise the electrical contact reliability will
be affected
4. FAQ
