The Fuse Block 0 to 30A K5/H 2 Pole from Littelfuse is an ideal solution for overcurrent protection in HVAC systems with Class H or K fuses. It offers a tight fit for Class H fuses for noncurrent-limiting systems with small interrupting ratings and Class K fuses for current-limiting systems with high interrupting ratings. The fuse blocks are easy to install on DIN rails or can be bolted down, and the open top allows access to fuses without removing them from the block. Additionally, these fuse blocks come with spring-reinforced clips that securely hold the fuses in place, ensuring reliable performance. The compact design of these fuse blocks saves space while providing effective protection against electrical overloads. With a durable construction and compatibility with standard UL Class H and K fuses, this Littelfuse fuse block is an essential component for any electrical installation.

These fuse blocks are compatible with UL Class H and K fuses that commonly provide overcurrent protection in older HVAC installations. They're used with Class H fuses for a noncurrent-limiting system with small interrupting ratings or Class K fuses for a current-limiting system with high interrupting ratings. Fuse blocks with spring-reinforced clips hold fuses tightly in place to maintain full electrical contact.
UL Class and midget fuse blocks accept fuses sized and rated according to UL Class or midget specifications. They have an open top for access to fuses, clips or studs for securing fuses within the block, and terminals for connecting to the circuit. These fuse blocks are either bolted down or mounted on a DIN rail to hold them in place. They're commonly paired with fuse box covers to enclose the fuses and prevent accidental contact. They are nonindicating, so there's no visual signal when a fuse is blown.
