High performance 'pigtail' fuses protect up to 1,500A

SCHURTER’s SHF 6.3x32 fuse provides higher voltage overcurrent and short circuit protection up to 1,500A at 500VAC/VDC within a range of rated currents in a compact package measuring 6.3x32mm. The high performance fuse is suited for primary AC circuit protection in 3-phase systems, HVAC systems, lighting and other industrial building and automation systems.

The new VDC and current ratings up to 32A provide primary protection in DC power systems for intelligent buildings, telecom centres, server farms and related peripheral systems. The combined AC and DC voltage ratings along with a detailed listing of breaking capacity ratings, and other precisely defined performance specifications, offer a reliable fuse approved for use in both alternating or direct current power applications.

The SHF 6.3x32 is available as a standard fuse link in 16 rated currents from 1-32A. Versions up to 8A are offered with pigtail leads for direct mounting on printed circuit boards. The standard fuse links can be used in a variety of panel or board mount fuse holders or clips for easy fuse replacement. SCHURTER also offers a full range of high current fuse holders and clips, compatible with the SHF, as well as its time-lag counterpart series SHT.

Direct compatibility with the most important competitive products, together with exceeding performance, makes the SHF 6.3x32 a form, fit, and function substitute product, as well as a fuse that fulfills newly defined application requirements, particularly those applications found in the area of DC power. The SHT 6.3x32 fuse is cURus approved and conforms to RoHS.

Key facts:

  • Certification according to UL 248-14, CSA C22.2 no. 248.14
  • High breaking capacity (H) up to 1,500A at rated voltage
  • High rated voltages up to 500VAC/VDC
  • 16 rated currents from 1-32A
  • Fast-acting (F) characteristics

Applications:

  • High-power 3-phase systems
  • Building automation: Heating, Ventilation and Air Conditioning (HVAC)
  • Photovoltaic: protection between inverter and grid
  • Frequency converters and ballasts
  • Power distribution and uninterruptible power supplies in datacentres
  • Higher voltage DC telecom and intelligent commercial building applications
