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
