High-Speed Semiconductor Fuses
Introducing
POWR-SPEED®
These certified high-speed fuses are optimized for performance and efficiency to better protect
your critical power semiconductors against short circuits. How is POWR-SPEED better? Backed
by over 40 years of experience, Littelfuse engineered the POWR-SPEED line to help you
protect critical power electronics from overcurrents that may cause damage to your equipment.
High-speed fuses are reliable, very fast-acting products that can reduce the amount of short
circuit current and improve the life of your power semiconductor devices.
The POWR-SPEED high-speed fuses are easy to retrofit as drop-in replacements where similar
products are currently being used. Custom designs are available if you need a specific fuse for
your application. Call us. Our engineers are eager to partner with you before, during, and long
after the design process to meet your specific needs.

Description
Littelfuse PSR series high-speed square body fuses are
specially designed for protection of power semiconductor
devices such as diodes, triacs, IGBTs, SCRs, MOSFETs,
and other solid state devices that are typically designed
into power conversion and power conditioning equipment.
Variable frequency drives, inverters, UPS, rectifiers, and
soft-starters are examples of typical equipment designed
with sensitive power semiconductor devices that cannot
withstand any line surge or overcurrent conditions and
require high-speed protection.
Littelfuse POWR-SPEED PSR series products offer
optimized circuit protection at the extremely fast speed
required to protect modern day power conversion devices.
Such products are commonly found in numerous applications
including pulp and paper industries, cranes and heavy-lifting
equipment, processing industries, wastewater treatment
plants, and various large factories and MRO facilities.

Description
Littelfuse PSR series high-speed square body fuses are
specially designed for protection of power semiconductor
devices such as diodes, triacs, IGBTs, SCRs, MOSFETs,
and other solid-state devices that are typically designed
into power conversion and power conditioning equipment.
Variable frequency drives, inverters, UPS, rectifiers, and
soft-starters are examples of typical equipment designed
with sensitive power semiconductor devices that cannot
withstand any line surge or overcurrent conditions and
require high-speed protection.
Littelfuse POWR-SPEED® PSR series products offer
optimized circuit protection at the extremely fast speed
required to protect modern day power conversion devices.
Available in bolted blade style termination (typical in North
American market) with visual blown fuse indication standard
on all fuses and optional micro-switch for external indication.
Features/Benefi ts
Best in class dc performance
Extremely current limiting
Superior cycling capability
Global certifi cation cURus, IEC
Visual and optional microswitch fuse blown indication
Low watt-loss design
Compliance with US and Canadian requirements
Class aR performance according to IEC60269-4
Applications
Power conversion devices (UPS, inverter,
rectifi ers, drives)
Dc systems (dc common bus, dc injection braking)
Battery protection application (energy storage systems)

Description
Littelfuse PSR series high-speed square body fuses are
specially designed for protection of power semiconductor
devices such as diodes, triacs, IGBTs, SCRs, MOSFETs,
and other solid-state devices that are typically designed
into power conversion and power conditioning equipment.
Variable frequency drives, inverters, UPS, rectifiers, and
soft-starters are examples of typical equipment designed
with sensitive power semiconductor devices that cannot
withstand any line surge or overcurrent conditions and
require high-speed protection.
Littelfuse POWR-SPEED® PSR series products offer
optimized circuit protection at the extremely fast speed
required to protect modern day power conversion devices.
Available in DIN43653 blade style termination with visual
blown fuse indication standard on all fuses and optional
micro-switch for external indication.
Features/Benefi ts
Best in Class dc performance
Extremely current limiting
Superior cycling capability
Global certifi cation cURus, CCC, IEC
Visual and optional microswitch fuse blown indication
Low watt-loss design
Compliance with US and Canadian requirements
Class aR performance according to IEC60269-4
Applications
Power conversion devices (UPS, inverter,
rectifi ers, drives)
Dc systems (dc common bus, dc injection braking)
Battery protection application (energy storage systems)
