Eliminating overcurrent phenomena: Rutronik offers the Littlefuse PSR series of high-speed fuses

Optimal protection for power semiconductor components: As electronic components continue to be miniaturized and their power increases at the same time, power semiconductors become more sensitive to overcurrent conditions and voltage pulses. Littelfuse's square box PSR series provides high-speed protection for these applications.

The PSR series of high-speed fuses are designed to protect power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFETs, and other semiconductor components used in power converters and process accessories. The Littlefuse product line provides circuit protection at very high speeds to meet the requirements of modern power converters.

Provides voltage pulse protection for a wide range of applications

These fuses are used in variable frequency drives, inverters, UPS, rectifiers and soft starters in applications such as the pulp and paper industry, cranes and heavy accessories, manufacturing or wastewater treatment plants. In addition, battery protection applications in energy storage systems, electric vehicle charging stations or heating and power systems also benefit from their high-speed fusing function.

Other advantages:

• Best in class DC performance

• Very high current limit and excellent cycling capability

• Direct busbar mounting design

• Designed for low power consumption

• Complies with IEC60269-4 global certification (cURus, CCC, IEC) and class-aR performance requirements

• Optional: Visual fuse blown micro switch indication
