Frequently Asked Questions
Q: What are the voltage specifications for the SY GDA 500MA ceramic fuse?
A: The SY GDA 500MA is rated for 250 VAC and 32 VDC (self-certified). It has an interrupting rating of 1500 A at 250 VAC, making it suitable for overcurrent protection in circuits operating within these voltage ranges.
Q: Is the SY GDA 500MA equivalent to Bussmann fuses?
A: Yes. The SY GDA 500MA is equivalent to the Bussmann BK/GDA-500MA. Both are 5x20mm fast-acting ceramic fuses with identical electrical specifications and can be used interchangeably in compatible applications.
Q: What does fast-acting mean for this fuse type?
A: Fast-acting refers to the speed at which the fuse element melts and interrupts current when an overcurrent condition occurs. The SY GDA 500MA has a typical I²t value of 0.038 A²s, meaning it responds quickly to protect sensitive electronic circuits from damage.
Q: What are the physical characteristics of the SY GDA 500MA?
A: The SY GDA 500MA is a 5x20mm ceramic tube fuse with nickel-plated brass endcaps. The ceramic construction provides excellent thermal stability, while the nickel-plated brass endcaps ensure reliable electrical contact and corrosion resistance.
Q: Does the SY GDA 500MA meet international standards?
A: Yes. The SY GDA 500MA complies with IEC 60127-2 international standards for fuses. This certification ensures compatibility with equipment designed to these specifications and validates its safety performance.
