Category
The SCHURTER 0001.2505 disposable fuse provides robust overcurrent protection for low-voltage DC and AC circuits with a 1.5kA interrupt rating and 1.25A continuous current handling. It operates reliably between -55°C and +125°C, making it suitable for automotive, industrial, and renewable energy systems. Critical design considerations include proper soldering techniques, thermal management, and compliance with voltage/current limits to prevent failure. While cost-effective for high-volume applications, its limited frequency response and lack of surge protection position it as a specialized solution for stable power systems requiring mechanical fusing.
