These time-delay fuses are suitable for high-current power applications. They can withstand current overload for a short time and will not open when exposed to harmless temporary surges, such as when starting a motor.
Breakthrough Current @ Voltage—Breakthrough current at voltage, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
