5ST 100-R Description

Short technical summary and product information.

The Bel Fuse 5ST 100-R is a 5x20mm glass tube time-lag fuse designed for low breaking capacity applications. It is rated for 100mA at 250VAC with a breaking capacity of 35A at rated voltage.

 

The slow blow (time-lag) characteristic allows the fuse to withstand temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive or inductive loads. The fuse meets IEC 60127-2 standard sheet 3.

 

The fuse is housed in a glass tube with nickel-plated brass caps and matte tin-plated copper leads. It requires a holder for mounting. Operating temperature range is -55°C to 125°C.

 

The 5ST 100-R is RoHS3 compliant, lead-free, and halogen-free. It holds safety approvals from CCC, CE, CSA, cURus, IMQ, SEMKO, and VDE.
