H079472 - D300SE24C40QF
Series: Protistor® size 300 aR, 2400VDC
Square Body High-Speed Fuse Protistor® Size 300 aR 2400VDC IEC 40A With Striker L Brackets
Mersen DC high performance power fuses were developed to provide superior protection for railway power circuits. These fuses are typically operated at more elevated temperatures than other fuse types. They have lower I2t to minimize damage to components in case of short circuits, and have lower watts loss and longer life.
