Eaton JJS-1 Class T Fuse 1 Amp 600 Volt

Product Description

The EATON JJS-1 is a Class T current-limiting fuse rated at 1 amp and 600 volts AC. Class T fuses are recognized for their compact form factor and high interrupting capacity, making them well suited for protecting sensitive electrical components in tight panel spaces. This fuse is installed by licensed electricians and electrical maintenance technicians working on industrial control panels, motor branch circuits, and related power distribution equipment where reliable overcurrent protection is required.

Class T fuses in the JJS series are used in commercial and industrial applications where high fault-current interrupting ratings are necessary and panel space is limited. Typical installation scenarios include motor starters, drive panels, control transformers, and branch circuit protection in manufacturing and mechanical room environments. The 600-volt rating covers a wide range of single-phase and three-phase distribution systems.

Key Features

• 1 amp current rating for low-amperage branch circuit and control circuit protection
• 600 volt AC rating suitable for a broad range of commercial and industrial distribution systems
• Class T form factor provides high interrupting capacity in a compact body
• Current-limiting design helps reduce arc energy and downstream damage during fault events

Compatibility

Designed as an OEM-style replacement Class T fuse for use in standard Class T fuse holders and fusible disconnect switches rated for 600 volts.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lock out the circuit before removing or installing fuses. Verify the replacement fuse matches the ampere and voltage ratings required by the circuit. Never substitute a higher-ampere fuse in place of the specified rating.
