Walter Fuse is produced by Walter Electronics Co., Ltd. (established in 1968) and is one of the earliest professional fuse manufacturers in Taiwan. Its products cover surface mount fuses, temperature fuses, square fuses, power fuses, etc., and are widely used in consumer electronics, automotive, communication, industrial systems, and other fields. The core advantage of Huade fuses lies in its comprehensive international safety certification system, which serves as both a global passport for product safety and a reflection of its technical strength. The following is a specific analysis:
1、 Overview of International Safety Certification
Huade fuses have undergone rigorous testing by mainstream global safety certification bodies, including:
North American market
UL certification (Underwriters Laboratories): covering most series, such as patch fuses, power fuses, etc., proving that the product complies with North American electrical safety standards.
CSA certification (Canadian Standards Association): on par with UL, meets the market access requirements of both North American countries.
European and Asian markets
VDE/T Ü V certification (German Institute of Electrical Engineers/German Technical Supervision Association): ensures that products comply with EU safety directives (such as the Low Voltage Directive).
CCC certification (China Compulsory Certification): For the Chinese market, such as the 2020 series square fuses.
KC certification (Korean safety mark) and PSE certification (Japanese product safety mark): supports the sales of products in the Korean and Japanese markets.
Other certifications
CUL certification (Canadian UL standard): Unique to some patch fuse series (such as 0603F).
SEMKO Certification (Swedish Electrical Safety Agency): Supplements Nordic market access qualifications.
2、 Certification details divided by product series
Due to differences in application scenarios, certification focuses vary among different product series
|Product Series | Applicable Fields | Safety Certification|
|0603F patch fuse | High temperature and high pressure environment for mobile phones, digital cameras, etc. | CUL, UL E56092 (some models)|
|2020 Square Fuse | PD Fast Charging, Gallium Nitride Charger, Small Appliances | CCC, UL, VDE, T Ü V, KC, PSE (fully certified)|
|TB temperature fuse | Home appliance over temperature protection (such as TB 2A 250V AC) | CUL, VDE, CCC, KC, PSE|
|WL55/WL55P power fuses | 5G communication, computer power systems | UL (core certification)|
3、 Technical support and market value of certification
Technical adaptability
Each certification requires testing for material composition, structural design, and extreme environmental performance (such as high temperature/high pressure). For example:
UL certification requires fuses to melt accurately at rated current without posing a fire risk.
VDE certification emphasizes long-term durability and insulation reliability.
Market competitiveness
The certification system helps Huade enter the high-end supply chain (such as gallium nitride fast charging and automotive electronics).
Compliant with lead-free and halogen-free environmental requirements, and compliant with EU RoHS and other directives.
4、 Certification Query Guide
Users can verify and validate through the following methods:
UL official website: Enter the certificate number (e.g. E56092) or company name "Walter Electronic".
National regulatory platform: For example, China CCC certification can be found on the official website of the State Administration for Market Regulation.
Third party platforms: Electronic component platforms such as Lichuang Mall provide certification labels (such as searching for model TE12810A250T001BG).
