Square Body DC Fuses — 1200Vdc: 160-420A


Specifications

Description: High speed fuses that provides superior protection in light and heavy harsh DC traction applications as 1200Vdc and below circuits, and as DC link/power converters.

Dimensions: See dimensions illustration.

 

Ratings: Volts: — 1200Vdc

Amps: — 160-420A IR: — 1200Vdc = 100kA L/R: 15 ms.

 

Agency Information: Consult Cooper Bussmann.

Electrical Characteristics

 

Arc Voltage

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.

 

Power Losses

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.
