NCLR45 - 45Amp Fuse

NCLR45 - 45Amp Fuse

Need a 45-amp Class R fuse for a compatible commercial or industrial electrical system? The NCLR45 is a cartridge-style, time-delay fuse rated for 45 amps at 600V AC, with a 200 kA interrupting rating. It's also current-limiting, helping restrict the amount of fault current that can pass through the circuit when the fuse operates under applicable fault conditions. The time-delay design is important, too. Some electrical equipment can briefly draw more current during startup or normal operation, and a time-delay fuse is designed to handle these short-duration increases while still protecting sustained overcurrent conditions. Measuring 3.0 inches high by 0.81 inches wide and 0.81 inches deep, the NCLR45 is a compact option for equipment designed to accept a fuse with these ratings, dimensions, and Class R configuration.

Key Features and Benefits

• 45 amp capacity for compatible circuits requiring a 45A fuse.
• 600V AC rating for use in appropriately rated electrical systems.
• 200 kA interrupting rating provides high fault-current interruption capability.
• Time-delay operation allows for temporary current increases that can occur during equipment startup.
• Current-limiting protection helps restrict fault current when the fuse operates.
• Class R cartridge design for compatible Class R fuse applications.
• Non-indicating construction without a visual blown-fuse indicator.
• At just 3.0 x 0.81 x 0.81 inches, it offers the required protection in a compact package.

Material Compliance and Certifications

Available specifications identify the NCLR45 as a Class R, time-delay, current-limiting fuse with a 45A rating and a 200 kA interrupting rating at 600V AC. The product data did not include specific agency certifications or material-compliance information, so we don't want to make claims we can't verify. For applications requiring a particular certification or compliance standard, refer to the appropriate product documentation before installation.

Where It Works Best

The NCLR45 makes sense anywhere the equipment specifically calls for its combination of Class R construction, 45A capacity, 600V AC rating, time-delay operation, and current-limiting protection. That can include compatible motor circuits, machinery, control equipment, and commercial or industrial electrical distribution systems.

The time-delay characteristic is particularly useful where brief startup currents are normal. When replacing a fuse, however, don't focus on amperage alone; check the full specification. Fuse class, voltage, interrupting rating, operating characteristics, and physical size all matter.
