The Schurter Inc. part number 0034.3128 is a glass tube fuse from the FST 5x20 series, designed for primary protection in electronic equipment. This cartridge fuse features a time-lag (slow-blow) characteristic, allowing it to withstand temporary inrush currents without nuisance opening.
With a rated current of 12.5 A and a rated voltage of 250 VAC, it offers a breaking capacity of 125 A. The fuse is constructed with a glass tube and nickel-plated copper alloy end caps, meeting IEC 60127-2 standards. Its operating temperature range spans -55°C to 125°C, suitable for demanding environments.
Measuring 5.2 mm in diameter and 20 mm in length, the 5x20 mm package requires a separate holder for mounting. The unit weight is approximately 1 gram. It holds certifications from CQC, cURus, PSE/JET, and VDE, ensuring compliance with international safety standards.
The melting I²t rating of 750 A²s provides additional guidance for coordination with upstream protection. Storage conditions are specified as 0°C to 60°C with maximum 70% relative humidity.
The current rating is 12.5 A.
The voltage rating is 250 VAC.
The breaking capacity is 125 A at rated voltage.
It has a slow-blow (time-lag T) characteristic, meaning it can tolerate temporary overcurrents.
The fuse is a 5x20 mm cartridge (5.2 mm diameter, 20 mm length).
The operating temperature range is -55°C to 125°C.
The fuse holds approvals from CQC, cURus, PSE/JET, and VDE.
