Semiconductor (AC) fuses
SCAC68
Protistor®Square-body Fuses
PSC aR sizes 3x - 450V to 700 VAC
Main characteristics
12/04
450 TO 700VAC / 63 TO 2800A
Exceptionally low I2T, Watt losses.
Non-magnetic construction,
Highly reliable low voltage
Trip-indicator system, conformity to UL,
IEC, DIN and VDE standards.
Increased technical performance
• Highter ratings
• Reduction in volume and weight
Recognized
This fuse preselection table indicates, for each size:
- rated current (or rating) In
- pre-arcing I2t (I2tp) at 1 ms
- total operating I2t (I2tt) at 660 V, f=50Hz cos ϕ=0.15, and for a total operating time from 8 to 10 ms
- dissipated power Pn at the rated current In, and at 0.8 In, in steady state
- breaking capacity at various voltages, checked by tests
made in accordance with IEC and American standards.
