Eaton 4A F Ceramic Cartridge Fuse 5 x 20 mm 250V AC Fast Acting S501-4-R

Eaton S501-4-R ceramic cartridge fuse is a fast acting protective device rated for 4A and 250V AC, designed to interrupt overcurrent conditions in low voltage industrial and electronic systems.

The fuse body is made from robust ceramic material, offering excellent thermal stability and fault containment to ensure quick clearing of fault currents while maintaining mechanical durability during operation.

Its cylindrical 5 x 20 mm form factor with a 5 mm diameter enables easy integration into panel-mounted and PCB fuse holders used across diverse applications.

This fuse meets multiple international certifications such as VDE, SEMKO, IMQ, CSA, CCC, and BSI, making it suitable for global installations requiring rigorous compliance and quality assurance.

Typical applications include control panel short-circuit protection, automation systems, safeguarding sensor and actuator lines, and power distribution boards in electronic equipment. It is also effective for protecting small motor control circuits where fast-acting fault interruption is critical.

Fast acting characteristic limits fault energy and improves circuit safety. 4A current rating provides precise overcurrent protection. 250V AC rating ensures safe operation at mains supply voltages. Ceramic construction enhances mechanical and thermal performance.

Compact 5 x 20 mm size fits standard fuse holders for convenience. Certified by VDE, SEMKO, IMQ, CSA, CCC, and BSI standards. Ideal for industrial automation and electronic equipment applications. Effective transient overload interruption with F speed fuse classification.
