UL 248-8 Class J

UL Listed; CSA Certified

Use this Eaton cartridge fuse to protect your home or office appliances against overcurrent and short circuits. Its compact dimensions of 21mm (diameter) and 57mm (length) make it useful in setups where space is limited. With a T-speed fuse rating, this is a slow-acting fuse and can accommodate voltage and current surges for a short period, so it's useful for devices with a high starting current. As a Class J fuse, it's commonly found in devices such as motor controllers, soft starters and transformers.

• Nickel-plated brass end caps for a reliable connection and corrosion resistance
• Low watt loss for energy efficiency
• High interrupting rating to safely intercept overcurrents of up to 300,000A
• Distinctive shape to ensure that it's not replaced by a different fuse type

A dual element fuse is a protective device that's designed for AC (alternating current) circuits where the short circuit current is not above 200,000A. It has a high thermal threshold and can be used for motor protection in high temperatures.
