Schurter launched its new UHS — a compact, fast-acting SMT fuse designed to safely interrupt high-energy overcurrent in the ”safety extra low voltage” (SELV) range. The new UHS is available in six current ratings from 50 to 100 A at 50 VDC or 32 VDC, with a breaking capacity of up to 2,000 A.
SELV may sound straightforward and harmless, but the growing use of powerful lithium-ion battery cells with increased storage capacity has created the need for a more cost-efficient, space-saving circuit protection solution. The challenge lies in meeting these increasing demands while continuing to ensure safety. Even within SELV, where voltage levels are considered safe for human contact, there is still a risk of dangerous high currents in the event of a short circuit.
