Product Description

The Schurter 0034.3125 6.3A T Glass Cartridge Fuse is a miniature fuse engineered for primary protection of electronic and electrical circuits, especially in devices calling for reliable overcurrent protection. Designed with a time-delay (slow-blow) characteristic, it tolerates short-term inrush currents and reduces unwanted nuisance tripping, making it ideal for loads that experience occasional surges.

Encased in a transparent glass body, the fuse enables users to visually inspect its status, simplifying maintenance and troubleshooting. The standardized 5 x 20 mm cartridge size ensures compatibility with numerous panel and board mount holders, widely used in industrial, commercial, and residential electronics.

This fuse operates up to 250V AC and supports a maximum rated current of 6.3A, safeguarding circuits up to these limits. Its low breaking capacity design is intended for applications where fault currents do not greatly exceed the fuse’s rated value. Typical uses include protection of small motors, power supplies, instrumentation, consumer electronics, and control panels.

The product’s performance remains stable over a broad temperature range, from -55°C to 125°C, furthering its versatility in environments prone to temperature fluctuations. The fuse complies with EN/IEC standards and offers safe operation for integration into regulated systems.

Key advantages include slow-blow functionality, low breaking capacity, visible fuse element, and robust glass construction. It is a standard solution for engineers requiring compact, reliable protection in boards, panels, and devices, with frequent applications in industrial automation, lab technology, manufacturing controls, and HVAC electronics.

For those seeking trustworthy cartridge fuse solutions, Schurter fuses exemplify Swiss engineering quality and compliance, allowing safe circuit operation and easy replacement when needed.
