Littelfuse JLLS225 Class T Fuse 225A 600VAC 20000A@300VDC Fast-Acting Knife-Blade Bolt-In

The JLLS Series circuit breakers from Littelfuse exemplify cutting-edge engineering designed to deliver exceptional performance and protection for sensitive electrical systems. With a robust interrupting rating of 20,000A at 300VDC, these molded case circuit breakers efficiently handle short circuit conditions, providing fast-acting overload protection for critical components such as variable speed drives and rectifiers. Their current limiting design not only safeguards against damaging surge events but also requires significantly less panel space compared to traditional Class R fuse blocks, promoting a more compact and efficient installation. Ideal for applications that demand reliable protection while minimizing equipment damage, the JLLS225 ensures your systems operate safely and effectively under various load conditions.
