A50QS

Semiconductor Protection Fuses

A50QS Amp-Trap

Form 101 fuses grew out of the need to improve the overall

performance of semiconductor fuses in response to new equipment requirements.

The A50QS encompasses the best protection features – lower I

t to provide better

protection for equipment, longer life when subjected to cyclic loading and lower

watts loss. A50QS is today’s best choice for the protection of dynamic solid state

equipment such as motor drives, inverters, UPS, etc.

Features/Benefits:

•

Lowest I

t for greatest protection of semiconductor circuits

•

Low watts loss for cooler operation

•

Superior cycling ability gives an equipment design advantage

•

State-of-the-art protection for 500V equipment

•

Ultra compact sizes allow down-sizing of existing equipment

Highlights:

•

500V AC/DC rated

•

Lowest I

•

Low watts loss

•

Superior cycling ability

Applications:

•

Protection of 500V or less motor

drives, UPS, inverters, etc.
