A70QS

Amp-Trap

Form 101

A70QS Amp-Trap

Semiconductor Protection fuses were developed in response to

the need for improved overall performance of 700V semiconductor fuses for new

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 I

t for improved protection of equipment

•

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

Highlights:

•

700V AC/DC rated

•

Very low I

•

Low watts loss

•

Superior cycling ability

•

All available with indicator (IL)

Applications:

•

Protection of 700V or less motor

drives, UPS, inverters, etc.
