5ST 2-R Description

Short technical summary and product information.

The Bel Fuse 5ST 2-R is a 5x20mm glass tube cartridge fuse designed for time-lag overcurrent protection. It is rated for 2A continuous current at 250VAC with a breaking capacity of 35A at rated voltage, complying with IEC 60127-2 standard sheet 3. The fuse features a slow blow response time, making it suitable for circuits with inrush currents. Melting I²t is 12 A²s.

 

The fuse body is made of glass with nickel plated brass caps and matte tin plated copper leads. It requires a holder for mounting and operates over a wide temperature range of -55°C to +125°C. The 5ST 2-R holds multiple safety agency approvals including CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE, and is fully RoHS3, REACH, Halogen Free, and Lead Free compliant.

 

Typical applications include power supplies, battery chargers, monitors, and adapters. The 5ST series is end-of-life with a last buy date of September 30, 2024; replacement series 0652C/0652P from Bel Fuse is available.
