Siemens 5SA271 Diazed Fuse

Siemens 5SA271 Diazed fuse link is a DIAZED fuse in size D II, designed for use with Siemens’ Diazed fuse bases in the SENTRON protection family. It carries a 20 A rated current (In) and a rated voltage of 500 V AC / 440 V DC (Un), with a general‑purpose gG characteristic for broad circuit protection in low‑ to medium‑power installations. As a plug‑in DIAZED link, the 5SA271 fits compatible D II holders and is intended for quick replacement in panels, distribution boards, and equipment that use the DIAZED form factor. The 5SA271 designation identifies a standard 20 A DIAZED link within Siemens’ DIAZED lineup, and the part is documented in Siemens Industry Mall and fuse catalogs as a DIAZED D II, 20 A, 500 V rating. This provides reliable protection for feeders and control circuits in systems that require a DIN‑style, interchangeable fuse solution, with Siemens’ support and compatibility across the DIAZED 5SA/SENTRON family.
