French Cylindrical

These Premium Amp-Trap

French cylindrical semiconductor fuses are an extension

ofthepopularA7OQSproductline.Theyaresolid-fill14mmand22mmfuses,IEC

rated 690VAC, 200kA Interrupting and 700VDC, 100kA interrupting at 10ms time

constant. In addition, these fuses have an 890 VDC rating for capacitor discharge

applications up to 2.5ms time constant. All ampere ratings are available with a striker.

Applications include small inverter drives and UPS systems, with superior l

t for

improved protection and performance.
