The AJT100-3PK refers to a Class J Time-Delay Fuse manufactured by Mersen (formerly Ferraz Shawmut). These fuses are designed to provide overcurrent protection in a variety of electrical circuits, offering a time-delay characteristic that allows for temporary inrush currents (like motor starting) without nuisance tripping. The '100' in the part number indicates a 100 Ampere rating, and '3PK' likely refers to a package containing three fuses.

Applications:

• Motor Circuits
• Transformers
• Panelboards
• Circuit Breakers
• HVAC Systems

Features:

• Class J Fuse
• Time-Delay Characteristic
• 100 Ampere Rating
• High Interrupting Rating
• UL Listed

Benefits:

• Provides robust overcurrent protection.
• Prevents nuisance tripping due to temporary inrush currents.
• Meets industry standards for safety and performance.
• Protects valuable equipment from damage.
• Easy to install and replace.

Additional Details:

Class J fuses offer a higher degree of current limitation compared to other fuse classes. The time-delay characteristic of the AJT100-3PK is crucial for applications involving motors and transformers. The high interrupting rating ensures that the fuse can safely interrupt high fault currents. Consult the Mersen datasheet for detailed specifications, including voltage ratings, time-current curves, and dimensions. Proper fuse selection is critical for electrical safety and system performance.
