Schurter High-Voltage Fuse Portfolio

Introduction

Schurter’s High-Voltage Fuse Portfolio is designed to provide dependable overcurrent protection in demanding DC power systems. Covering a broad range of current, voltage, and interrupting requirements, these fuses support modern high-power equipment where safe fault isolation is essential.

Part Description

The Schurter High-Voltage Fuse Portfolio includes A-series and E-series high-voltage DC fuses for automotive, energy, and industrial applications. The range supports system voltages up to 1000 V DC and current ratings from 10 A to 1100 A.

With breaking capacities up to 50 kA, these fuses are intended to safely interrupt severe fault currents that may occur in high-energy battery packs, power-conversion equipment, charging infrastructure, and DC distribution systems. Their scalable ratings allow designers to select protection devices appropriate for both compact power electronics and large energy-storage installations.
