High Speed Fuses - Square body flush end contact,1000V (IEC),50-1400A (-GKN/-Type K Indicator for Micro)

Square body flush end contact high speed fuses.

See dimensions illustration.

CE, Designed and tested to/IEC 60269: Part 4, UL Recognized.

@ Excellent dc performance
@ Low arc voltage and low energy let-through (I2t)
@ Low watts loss
@ Superior cycling capability

@ DC common bus
@ DC drives
@ Power converters/rectifiers
@ Reduced voltage starters

This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as a function of the applied working voltage Eg, (rms) at a power factor of 15%.

The total clearing I2t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (rms).

**Overall length is 90mm, for all other fuses the overall length is 75mm. @ Watts loss provided at rated current. @ Microswitch ordered separately.

Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the power losses at load currents lower than the rated current. The correction factor, Kp, is given as a function of the RMS load current, Ib, in % of the rated current.
