Bussmann JJS-3 3A 600V Fast-Acting Class T Fuse

Description

Bussmann JJS-3 3A 600V Fast-Acting Class T Fuse

The Bussmann JJS-3 is a fast-acting, current-limiting fuse from Eaton’s Bussmann series. Designed for electrical circuit protection, it helps interrupt excessive current and limit fault energy when used in a correctly rated system.

Its compact cylindrical construction and ferrule-end connections are designed for use with compatible Class T fuse holders. The JJS series is also used in applications such as variable-frequency drive (VFD) line protection.

– Electrical distribution systems designed for Class T fuses
– Compatible industrial electrical equipment
– Applications requiring current-limiting overcurrent protection

Compatibility and Selection Guidance

Before replacing a fuse, confirm the required current rating, operating voltage, fuse class, interrupting rating, dimensions, and compatible fuse holder. A fuse should never be selected by amperage alone, and a different fuse class should not be substituted without checking the equipment manufacturer’s requirements.

The JJS-3 is rated at 600V AC; do not assume that the same rating applies to DC circuits. Consult the manufacturer’s documentation for the intended application.
