Emerson Thermodisc Fuses G4a01125c G4a00125c | Operating Temperature 125℃, 10a, 250v
How to choose between 10A and 15A?
Emerson's Thermodisc G4A01125C and G4A00125C are high-precision thermal fuses belonging to the G4A series. Both have a rated operating temperature of 125°C and are reliable guardians for equipment overheat protection. The core difference between the two lies in the rated current and breaking capacity: G4A01125C is suitable for circuits with a current of 10A, while G4A00125C can withstand a current of 15A. When choosing, please determine the model according to the working current of your equipment to ensure a safety margin.

In - depth interpretation of application scenarios
G4A01125C (10A) Typical applications: More suitable for devices with relatively low power, such as power adapters, chargers, small transformers, office equipment (printers/copiers), etc.
G4A00125C (15A) Typical applications: Due to its stronger breaking capacity, it is often used in kitchen appliances (coffee makers/kettles), electric irons, motors with higher power or industrial control equipment.
Frequently Asked Questions (FAQ) in model selection
Q: Can the 15A G4A00125C directly replace the 10A G4A01125C?
A: From a safety perspective, it can. However, installation dimensions and costs need to be considered. It is recommended to replace it with the original specification. Conversely (replacing a large - current one with a small - current one) is prohibited.
Q: What is the significance of the operating temperature accuracy of ±2°C?
A: High accuracy ensures the timeliness and consistency of protection, prevents the device from operating at critical temperatures, and extends its service life.
