Littelfuse JLLN070 Class T Fuse 250 Volt

Product Description

The LITTELFUSE JLLN070 is a Class T fast-acting fuse rated for 70 amps at 250 volts. Class T fuses are designed for high-interrupting-capacity applications where space is limited and reliable overcurrent protection is required. Their compact form factor and high fault-current interrupting ratings make them well suited for protecting sensitive electrical equipment, drives, and power distribution panels in demanding trade environments. Licensed electricians and industrial maintenance technicians are the primary installers of this fuse type.

The JLLN070 is used in commercial and industrial electrical systems where a Class T fuse holder or fusible disconnect is specified. Typical applications include motor control centers, variable frequency drives, power supplies, and branch circuit protection panels operating on 250-volt systems. This fuse type is commonly specified when high available fault current requires a fuse with a high interrupting rating in a compact package.

Key Features

• Class T fast-acting fuse construction for high-speed overcurrent protection
• 70-amp current rating for branch circuit and equipment protection
• 250-volt AC rating suitable for single-phase and multi-phase distribution systems
• Compact Class T form factor fits standard Class T fuse holders and disconnects
• High interrupting capacity for use in circuits with elevated available fault current

Compatibility

Designed as a direct-replacement Class T fuse for use in standard Class T fuse holders and fusible disconnect switches rated for 250 volts and 70 amps.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before replacing a fuse. Verify that the replacement fuse matches the voltage and amperage rating specified for the equipment. Never substitute a fuse with a higher amperage rating than what the circuit is designed for.
