DATA SHEET
Thermal Cutoff SEFUSETM
SM/G SERIES
FUSIBLE ALLOY THERMAL SENSITIVE TYPE,
0.5 AMPERES (250 Va.c.) and 3 and 5 AMPERES (50 Vd.c.) Rated Current
The NEC's SEFUSE (SM/G series) is a small, solid and reliable thermal cutoff that can be used under 0.5 A / 250
Vac. 3 and 5 ampere / 50 Vdc. electrical rating type, added to the product line-up lately, is also available. It
protects home appliances and industrial equipment from fire and accident by opening of electrical circuit if it
senses an abnormal temperature rise.
FEATURES
™ Approved by UL (USA), CSA (Canada), VDE (Germany), BEAB (UK) and MITI (Japan)
™ Very small
™ Conpact, durable and veliable by hermetic seal structure.
™ Excellent sensitive to abnormal temperature rise and high accuracy in operation.
™ Stable characteristics in a long-term.
™ Capable of opening at a cutoff current of AC 0.5 amperes and DC 3 and 5 amperes.
™ One shot operation.
APPLICATIONS
Transformers
Motors
Battery packs
Electric home appliances
Electric Industrial equipments,
Office automation equipments, etc.

Cautions
This section describes cautions designed to protect the performance of the thermal cutoff, Be sure to read and
fully understand these cautions.
To obtain full performance from the thermal cutoff, it is necessary for the customer to appropriately store
the thermal cutoff, design appropriate circuits for the application, and perform evaluations, mounting and
testing as necessary. Problems arising from the inappropriate execution of the above are the responsibility
of the customer, and NEC declines any and all responsibility.
Design Cautions
q Do not use this device for any purpose other than as a thermal cutoff.
The thermal cutoff is designed to detect abnormal rises in temperature and break circuits if needed. It is not
a current fuse that cuts excess current. If used as a current fuse, the SEFUSE may malfunction.
q Do not use this device in aerospace equipment, aeronautical equipment, nuclear reactor control systems, Iife
support equipment or systems, transportation machinery engine control or safety-related equipment.
This device is designed for use in household electric appliance, office automation equipment, audio and video
equipment, computer and communications equipment, test and measurement equipment, personal electronic
equipment and transportation equipment (excluding engine control).
q The customer should select the proper thermal cutoff device, mounting location, and mounting method as
appropriate for each application.
Verify whether the chosen selections are appropriate by repeatedly testing the final design for thermal cutoff
under normal conditions as well as under predicted maximum abnormal conditions.
q Make designs so that the temperature of the body of the thermal cutoff does not exceed the temperatures
shown in Table 1.
If, these temperatures are exceeded on a regular basis, the thermal cutoff may start operating only at tem-
peratures lower than the normal operating temperature. Malfunctions may also occur. Even if the thermal
cutoff's operating temperature is exceeded, it may malfunction.

∗1) : The temperature does not means ambient temperature but surface temperature on
thermal cutoff.
∗2) : When a large current flows through a thermal cutoff, temperature difference occurs
between the case and the lead. Therefore, it is recommended to measure some points
on the thermal cutoff, and make design so that the highest temperature does not exceed
the temperature shown in Table 1.
