250MW High Speed British Standard Fuse 690V, 250A
This part is obsolete, please contact our team for a modern day alternative on 01444 243 452 / enquiries@gdrectifiers.co.uk
The 250MW 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
The offset bolted tag design is compatible with many industrial distribution panels and fuse holders and provides a secure terminal connection.
Semiconductor protection fuses are used to protect against overcurrent in power electronic equipment. Semiconductor fuses are specifically designed to reduce the I2t, peak let-through current and arc voltages during a fault to protect and isolate semiconductor components such as diodes, thyristors and SCRs.
