A30QS
Semiconductor Protection Fuses
A30QS Amp-Trap
®
Semiconductor Protection fuses are intended for the protection
of Power Semiconductors such as diodes, phase control SCR’s and other power
semiconductor devices. The A30QS is recommended for new applications providing
solutions for your critical protection needs at 300V and less semiconductors.
Features/Benefits:
•
Low I
2
t minimizes damage to protected component on short circuit
•
Controlled arc voltage reduces stress to circuit components during
fuse clearing
•
Choice of mounting types helps in equipment design
Highlights:
•
Fast acting
•
Current-limiting
•
Low I t
