Usage Of The Thermal Links 20A 250V 102C 115C 125C 130C 150C Cutoff
1. When atmosphere pressure is from 80 kPa to 106 kPa, the related
altitude shall be from 2000 meter to -500 meter.
2. Operating voltage less than rated voltage of ATCO, operating
current less than rated current of ATCO.
3. Do not touch the ATCO body or lead wires directly when power is
on, to avoid burn or electric shock.
Replacement Of The Thermal Links 20A 250V 102C 115C 125C 130C 150C
Cutoff
ATCO is a non-repairable product. For safety sake, it shall be
replaced by an equivalent ATCO from the same manufacturer, and
mounted in the same way.
Storage Of The Thermal Links 20A 250V 102C 115C 125C 130C 150C
Cutoff
Do not store the ATCO at the high Temp., high humidity or corrosive
gas environment, avoid influencing the solder-ability of the lead
wires, the product shall be used up within 1 year after receiving
the goods.
Installation Of The Thermal Links 20A 250V 102C 115C 125C 130C 150C
Cutoff
Make Sure the Temp. of Installation Position.
1. It is recommended that a dummy ATCO with inbuilt thermo-couple
shall be used to determine the proper Temp.
2. The terminal product should be tested to ensure that potential
abnormal conditions do not cause ambient Temp. to exceed the Tm of
the ATCO.
3. Mount the ATCO at the location where Temp. rises evenly.
4. The surface Temp. of TCO less than the holding temp of ATCO.
5. The seal or body of TCO must not be burned or over heated.
Installation position of mechanical performance requirements.
1. Do not locate the ATCO in a place where severe vibration always
occurs.
2. Ensure that the lead wire is long enough, and avoid actions such
as press, tensile or twist.
3. The seal or body of TCO must not be damaged.

Cutoff
TCO
Thermal-Link
A non-resettable device incorporating a THERMAL ELEMENT which will
open a circuit once only when exposed for a sufficient length of
time to a temperature in excess of that for which it has been
designed.
ATCO
Alloy Thermal-Link
Alloy Type Thermal-Link, Alloy is the thermal element.
Tf
Rated Functioning Temp.
The temperature of the Alloy Thermal-Link which causes it to change
the state of conductivity with a detection current up to 10 mA as
the only load.
Tolerance: Tf + 0 / - 10 °C (GB 9816.1, EN 60691, K60691).
Tolerance: Tf ± 7 °C (J60691).
Fusing Temp.
The temperature of the Alloy Thermal-Link which causes it to change
its state of conductivity is measured with silicone oil bath in
which the temperature is increased at the rate of 0.5 °C to 1 °C /
minute, with a detection
current up to 10 mA as the only load.
Th
Holding Temp.
The Maximum temperature at which a Alloy Thermal-Link will not
change its state of conductivity when
conducting rated current for 168 hours.
Tm
Maximum Temp. Limit
The temperature of the Alloy Thermal-Link stated by the
manufacturer, up to which the mechanical and electrical properties
of the Alloy Thermal-Link having changed its state of conductivity,
will not be impaired for a given time.
Ir
Rated Current
The current used to classify a Alloy Thermal-Link, which is the
Maximum current that Alloy Thermal-Link allows to carry and is able
to cut off the circuit safely.
Ur
Rated Voltage
The voltage used to classify a Alloy Thermal-Link, which is the
Maximum voltage that Alloy Thermal-Link allows to carry and is able
to cut off the circuit safely.
In
Nominal Discharge Current
Being able to withstand 15 peak currents of waveform 8 / 20 μs to
test the product's durability of withstanding pulse current.
Imax
Maximum Discharge Current
Bing able to withstand 1 peak current of waveform 8 / 20 μs to test
maximum pulse current that the product can with stand.
