Overview

The Mersen W1069036 Protistor® Size 2x33 aR high-speed fuse-link delivers ultra-fast semiconductor protection in power conversion systems operating at 690VAC (IEC) or 700VAC (UL). Designed for critical applications, this fuse-link protects diodes, thyristors, and IGBT devices with a rated current of 1800A and a breaking capacity of 200kA. Its square body design incorporates flush metric threads with omega connections for simplified installation in compact enclosures. The fuse elements are die-cut and embedded in solidified sand to optimize arcing control, resulting in very low I²t values for reduced thermal stress and enhanced protection margins. Silver-plated contact surfaces and non-magnetic hardware ensure superior conductivity and corrosion resistance. With a power dissipation of 260W at rated current, this fuse-link complies with IEC 60269-4 and is UL/CSA Recognized (E76491 for some items), ensuring global interoperability. An optional low-voltage trip-indicator is available for visual or remote fault signaling. Ideal for inverters, motor drives, UPS systems, and renewable energy applications, the W1069036 is part of Mersen’s Protistor® series, engineered for state-of-the-art semiconductor protection in demanding high-energy circuits.
