NEC SCHOTT SEFUSE™ SM Type
he NEC SCHOTT SEFUSE™ SM type is a thermal cutoff designed to protect electrical home appliances and industrial electrical equipment from catching fire. It contains a fusible alloy inside an insulated case which interrupts the electrical circuit by melting when ambient temperatures reaches abnormal levels.
Product Advantages
SM type thermal cutoffs:
- Are stable and operate with precision to ensure maximum safety for the operation of electrical equipment
- Can be mounted directly where temperature detection is required without insulation
- Have fast thermal response due to their shape and small size
- Have a resin-seal which ensures strong reliability and accuracy
Applications
The SM type is used in many different electrical products, such as in power supplies, motors, battery packs and automobiles.
