Mersen A70P3504 is a 350-amp, 700-volt AC/DC rated semiconductor protection fuse designed for high-speed overcurrent protection of power diodes, thyristors, and other sensitive power electronic devices. It provides a high interrupting rating of 200,000 amps RMS symmetrical at 700VAC, ensuring robust fault clearing in demanding industrial circuits. The fuse features a compact, rectangular body with blade-style terminals for bolted connections, constructed with a ceramic body and silver-plated elements for reliable, low arc voltage performance. It complies with UL 248-13 and IEC 60269-4 standards for semiconductor fuse applications. Typical uses include protection of variable frequency drives, UPS systems, DC power supplies, and other power conversion equipment in heavy industrial environments.
