Fuses for Semiconductor Protection Standard Type IEC 60269, BS 88 Size 1

SVP’s square body fuses type SVPSC are available in four different body sizes. Each size is available in

various mounting styles for global applications.

Variety in body sizes ,mounting style and amp ratings allow maximum flexibility in equipment design.

SVPSC fuses provide superior engineering for the

protection of today’s power semiconductors. The silicate process, together with special shape and form of the

pure silver melting elements, give excellent results of low I2t-values and high interrupting ratings. They are also

the most reliable under high cyclic loading conditions.

All fuses can be fitted without micro switches.

Square Body Applications

Maximum Permissible Load Current

The rated current value of fuses is based

on the ambient temperature in the space immediately below

the fuse of 20°C. The following graph gives correction factors

(k) for a range of temperatures (–40°C to +80°C). Maximum

permissible continuous load currents can be calculated by

applying the following formula:

Temperature Correction Curve

The maximum permissible continuous load current Ib of a

fuse can be checked empirically (i.e., by satisfying the

formula below) by making simple voltage and temperature

measurements under actual operating conditions after the

fuse has been installed in its operating location and loaded

at the calculated Ib value:

E2 / E1 ~ (0.92 + 0.004t) ≤ N w

where E1 = Voltage drop across fuse after 5 seconds

E 2 =Voltage drop across fuse after 2 hours s

T = Air temperature at start of test (C°)

N = Constant Fuse Rated Voltage (IEC) N
