Precautions for Rating
a.
The power supply voltage must be less than or equal
to the rated voltage of the device. Operation above the
voltage rating may result in device damage, smoke or
flame.
b.
Designs must be selected in such a manner that the
device hold current is higher than the normal current
value in the circuit. Selecting device hold current that is
too low for the application may interrupt the circuit under
normal usage conditions.
c.
This product should not be used in an application where
the maximum short circuit current available exceeds the
rated maximum breaking current of the product.
Handling Precautions
a.
The device is composed of plastic parts, please do not
clamp or dent the housing with a tool as this might cause
a resistance increase and product damage.
b.
When welding product terminals or mounting the breaker
on battery (cell), please be careful not to apply excessive
bending, twisting or force on the product and terminals.
The excessive stress might cause a resistance increase or
product damage.
Please refer to following cautions.
• Do not apply more than 10N bend force to product.
(Fig. 1)
• Do not apply more than 1.5cN*m twist torque to the
product. (Fig. 2)
• Do not apply more than 20N deflection force to product.
(Fig. 3)
• Do not apply more than 2N force to the terminals.
(Fig. 4)
• Do not apply more than 0.6cN*m twisting torque to the
terminals. (Fig. 5)
• Do not bend the terminals more than 45° at the end.
(Fig. 6)
• Should not twist terminals more than 20°C with breaker
body fixed.
c.
Product terminals can be welded using direct welding
and series welding methods. In either case, please use a
suitable Jig so that the device will not be subjected to the
stress conditions listed above.
d.
Pull strength and detach strength of the terminal welds
are per user requirements. However, if the welding is
controlled by resistance, the measurement should be
made as close as possible to the weld point by a “4-point
clip method” using milliohm meter to ensure accuracy.
e.
Please avoid putting the stress on the device, as listed
above, when a jig, fitting or additional welding process is
used. Please re-confirm the resistance value whenever a
new process is added.
d.
The devices are intended for protection against damage
caused by occasional over current or over temperature
fault conditions and should not be used when repeated
fault conditions or prolonged trip events are anticipated.
e.
The devices may not perform as specified if mechanical
pressure is added while the device is in the tripped state
or exposed to temperature conditions over 100°C or in
temperature conditions under -30°C.
