NEC-SCHOTT
Thermal cutoffs and overtemperature protection
About the manufacturer
NEC SCHOTT is a legacy designation associated with Japanese thermal-protection components and the SEFUSE thermal-cutoff family. These devices arose from the development of compact safety components intended to disconnect electrical equipment in the event of overheating. The range includes one-shot thermal cutoffs that open the circuit at a specified temperature. Because the products have been associated with changing corporate and brand structures, the full series designation and current technical documentation are essential for accurate identification.
The main technical solutions associated with NEC-SCHOTT include SEFUSE thermal cutoffs, single-operation thermal links and SF-series thermal protectors. Thermal cutoffs interrupt a circuit at a defined temperature to help protect equipment from overheating. Single-operation thermal links use a triggering mechanism matched to their temperature and electrical ratings. Correct placement within the appliance influences response.
Applications
NEC-SCHOTT solutions are relevant to applications where component characteristics must be matched to the final equipment:
- home appliances
- power supplies and transformers
- electric heaters
- small motors
- consumer electronics
- overtemperature protection
