Eaton JJN-15 Class T Fuse 15A 300V

Product Description

The EATON JJN-15 is a Class T current-limiting fuse rated at 15 amps and 300 volts AC/DC. Class T fuses are recognized for their compact form factor and high interrupting capacity, making them a reliable overcurrent protection device in space-constrained electrical panels and equipment. This fuse is designed for use in branch circuit and feeder applications where fast-acting, current-limiting performance is required. Licensed electricians and industrial maintenance technicians install this type of fuse in commercial and light industrial settings as part of a compliant overcurrent protection scheme.

The JJN-15 is suited for 300-volt branch circuit applications including motor branch circuits, control panels, power distribution equipment, and industrial machinery. Its Class T form factor allows installation in space-limited enclosures where larger fuse classes cannot be used. The fast-acting, current-limiting design helps protect downstream equipment from the damaging effects of fault currents.

Key Features

• Class T form factor for compact, space-saving installations
• 15-amp continuous current rating for branch circuit protection
• 300-volt AC/DC rating for low-voltage distribution systems
• Current-limiting design reduces let-through energy during fault conditions
• Fast-acting response protects sensitive downstream equipment

Compatibility

Designed as an OEM-style replacement for Class T fuse holders and fused disconnects rated for 300-volt, 15-amp overcurrent protection applications.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lockout/tagout the circuit before replacing any fuse. Verify that the replacement fuse matches the ampere rating, voltage rating, and fuse class specified on the equipment nameplate. Never substitute a fuse with a higher ampere rating than what is required by the circuit design.
