S506-1-R Description

Short technical summary and product information.

The S506-1-R is a time-delay glass tube fuse designed for reliable circuit protection in AC and DC applications. Rated for 1 ampere at 250VAC, this component provides a 35A interrupting capacity and operates according to IEC 60127-2/3 standards. Its slow-blow response time allows temporary inrush currents without nuisance tripping, making it suitable for sensitive electronics and power supplies.

 

Constructed with a glass tube body and nickel-plated brass endcaps, the S506-1-R measures 5mm in diameter by 20mm in length. It requires a compatible fuse holder for mounting and features axial leads for easy installation. The fuse carries extensive global certifications including UL, cULus, VDE, BSI, SEMKO, IMQ, PSE/JET, and CCC, ensuring compliance across diverse markets.

 

Engineers can rely on the S506-1-R for stable performance under rated conditions, with a typical DC cold resistance of 0.0757 ohms and a melting I²t of 6.45 A²s. This robust design supports continuous operation while safeguarding downstream components against overcurrent faults.
