A30QS Amp-Trap® high speed fuses are intended for the protection of Power Semiconductors such as diodes, phase control SCRs and other power semiconductor devices. The A30QS is recommended for new applications providing solutions for your critical protection needs at 300V and less semiconductors.

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 I2t 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.

A50P Amp-Trap® Form 101 high speed fuses were developed for DC drives, uninterruptable power supplies and similar applications requiring better protection (lower I2t) and superior reliability. The A50P is typically used for replacement.

A70QS Amp-Trap® high speed fuses were developed in response to the need for improved overall performance of 700V semiconductor fuses for new equipment requirements. A70QS fuses have lower I2t 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.

A100P Amp-Trap® Form 101 high speed fuses are rated 1000V, extending the range of protection for UPS systems, AC and DC drives, reduced voltage motor starters and similar applications where lower I2t and superior reliability are needed. With ratings from 15 through 1000 amperes, a wide range of high voltage applications can be served.

A70P Amp-Trap® Form 101 high speed fuses were developed for higher voltage AC and DC drives, UPS systems, reduced voltage motor starters and similar applications where lower l2t and superior reliability are needed. A70P is a very popular fuse, available in a wide range of ratings. Typically used for replacement.

A70Q Amp-Trap® high speed fuses were developed for inverter applications requiring extremely low I2t. A70Q fuses provide the most responsive protection for applications not required to sustain heavy overloads. Typically used for replacement purposes.

A60Q Amp-Trap® Form 101 high speed fuses feature the only 600V AC / DC rating in the industry of similar size (1-1/2" x 13/32") fuses protecting semiconductors. A60Q also has the lowest l2t of all similar fuses and excellent cycling ability. Applications include inverters and small equipment requiring extremely fast response to faults, without the need to carry sustained heavy overloads.

A60X Amp-Trap® Form 101 high speed fuses are popular for the protection of higher voltage heavy rectifiers such as traction rectifiers. They can carry long sustained overloads common with heavy duty apparatus. 700A through 2000A sizes are of compact, hockey-puck design, able to provide high power protection in a small space.

A120X Amp-Trap® Form 101 high speed fuses, rated 1/2A through 30A, 1200VAC are popular for use in traction drive auxiliary circuits and similar applications. A120X fuses are also suitable for use on 1000VDC auxiliary circuits with low time constants.
