ESO 10.3x38 – fuse inserter, extractor and cover in oneWith the ESO 10.3x38, Schurter is introducing a multifunctional fuse cover for use on printed circuit boards. The ESO 10.3x38 can be used simultaneously as an inserter, extractor and cover for fuses. Designed for use with Schurter’s CSO fuse clips, and the ASO 10.3x38 fuse, the combination provides touch-safe circuit protection up to 1500V DC.

The demand for compact components for use on circuit boards is constantly growing, including in solar applications. Schurter is meeting these requirements with its patented ESO 10.3x38. With the ESO 10.3x38, fuses with the 10.3x38mm format can be simply and securely attached to clips. Upon inserting the ESO 10.3x38 with captive fuse into the fuse clips, the installation provides a touch-safe cover according to IP20 specifications. If the fuse is triggered, then the ESO 10.3x38 can also be used as a fuse removal aid. Additional tools are not required. If the ESO 10.3x38 is used together with Schurter’s CSO fuse clips, and the Schurter’s ASO 10.3x38 fuse, then these form a fully compatible, safe and cost-effective combination.

In addition to numerous applications in the energy and industrial sectors, the ESO 10.3x38 is particularly suitable for protecting solar applications with rated currents of up to 32A or rated voltages of up to 1500V AC/V DC. Specific applications include solar inverters, string fuse boxes and battery charge controllers based on printed circuit boards. Standard terminal markings can also be optionally attached for simple identification of the fuse. When combined with the CSO fuse clip from Schurter, the ESO 10.3x38 has cURus certification.

Technical specifications:

  • Rated voltages of up to 1500V AC / V DC
  • Rated currents of up to 32A
  • Degree of protection IP20
  • cURus approval
