500ma Slow-Blow Fuse
A 500mA slow-blow fuse is an electrical safety device with a current rating of 500 milliamperes (0.5 amperes). It is designed to protect electrical circuits and equipment from overcurrent conditions. Slow-blow fuses, also known as time-delay fuses, have a delayed response to overcurrent’s, allowing them to tolerate temporary current surges while still providing protection against sustained overloads.
These fuses are typically used in applications where precision and time-delayed protection are essential. When an overcurrent situation occurs, the fuse's delayed response allows it to withstand temporary current spikes that may be common during normal operation. However, if the overcurrent condition becomes sustained and potentially damaging, the fuse will eventually blow to interrupt the circuit, preventing damage to the electrical system and connected devices.
