Overview

The Mersen Protistor® N302232 is a high-speed, square body fuse-link engineered for critical semiconductor protection in power conversion equipment. This aR class fuse-link, rated at 33 Amperes, provides precise overcurrent and short-circuit protection for sensitive electronic components such as diodes, thyristors, and IGBT devices. It features a voltage rating of 600VAC (IEC) and 650VAC (UL). The Size 2x33 designation, combined with striker plate mounting and metric threaded holes (M10), ensures compatibility with a wide range of equipment designs, including those requiring metric fasteners. Key performance specifications include a pre-arcing I²t of 1855 kA²s and a clearing I²t of 8800 kA²s at rated voltage, delivering robust protection against fault conditions. The internal construction utilizes die-cut elements embedded in solidified sand, which precisely controls arcing characteristics to minimize damage to protected equipment. With a high interrupting rating of 2800A, the N302232 effectively interrupts fault currents while maintaining a low power dissipation of 330W at rated current. The fuse-link is equipped with silver-plated contact surfaces and non-magnetic hardware for reliable operation. An optional low voltage trip-indicator can be integrated, activating a field-mountable microswitch for remote status monitoring. The indicator lever becomes visible after the fuse operates, providing clear visual confirmation of fault conditions. The dimensions for the N302232 are 136.9 mm x 59 mm x 59 mm. This fuse-link is ideal for applications in renewable energy systems, motor drives, and industrial power supplies, ensuring fast-acting, reliable protection to extend the lifespan of critical semiconductor components.
