450MMT High Speed British Standard Fuse 690V, 450A
The 450MMT is a high speed British standard fuse designed and tested to BS88-4 and IEC 60269-4. It features excellent cycling capability and suited to power converters, rectifiers and reduced voltage starters.
- Excellent cycling capability and DC performance
- Low arc voltage and low energy let-through (I2t)
- Low watts loss
- Ideal for DC drives
- Designed and tested to BS88 part 4
Bussmann series fuses play a major role in industrial or commercial facilities by providing reliable, maximum protection to power systems. Their physical size or rejection features prevent replacing a fuse with one from another fuse class. This helps ensure the correct replacement fuse is always installed and the voltage and interrupting ratings remain the same.
