Cautions and warnings
Depending on the sensor material the short-circuit spring does not trigger until 180 °C is reached.
Thermal radiation to adjacent components must be taken into consideration in the circuit design.
Depending on the mounting position, the surge arrester may have to be secured by additional
mechanical means.
Do not continue to use surge arresters whose short-circuit mechanisms have been activated.
If the contacts of the surge arresters are defective, current load can cause sparks and loud
noises.
Do not operate surge arresters in power supply networks, whose maximum operating voltage
exceeds the minimum spark-over voltage of the surge arresters.
Surge arresters may become hot in the event of longer periods of current stress (burn risk). In the
event of overload the connectors may fail or the component may be destroyed.
Surge arresters must be handled with care and must not be dropped.
Do not continue to use damaged surge arresters.
Display of ordering codes for EPCOS products
The ordering code for one and the same EPCOS product can be represented differently in data
sheets, data books, other publications, on the EPCOS website, or in order-related documents such as
shipping notes, order confirmations and product labels.
The varying representations of the
ordering codes are due to different processes employed and do not affect the specifications of
the respective products.
