A70QS

Semiconductor Protection Fuses

A70QS Amp-trap Semiconductor Protection fuses were
®
developed in response to the need for improved overall
performance of 700 volt semiconductor fuses for new
2
equipment requirements. A70QS fuses have lower I t for
better protection, longer life when subjected to cyclic
loading, plus lower watts loss. A70QS is the best choice
to protect dynamic solid state equipment
such as motor drives, UPS, etc.

Features/Benefits
• Very Low l t for improved protection of equipment
2
• Superior cycling ability for long,reliable life
on high cyclic loading
• Low watts loss for cooler operation
• 700V AC/DC rating gives greater design versatility

• Ultra compact sizes allow down-sizing
of existing equipment
