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

2
• Low l t minimizes damage to protected
components on short circuit
• Controlled arc voltage reduces stress to circuit
components during fuse clearing

• Choice of mounting types helps in equipment design
