Key Features and Benefits
Fast-Acting Circuit Protection
The JJS-60 is designed to respond to overcurrent conditions and help limit the effects of short-circuit faults when applied within its ratings.
High Interrupting Capacity
Its 200kA interrupting rating at 600V AC makes it suitable for circuits where the available fault current and system voltage meet the fuse’s published limits.
Compact Class T Cartridge Design
The compact form is useful in compatible Class T fuse assemblies. Physical dimensions alone do not establish compatibility; the fuse class and holder specification must also match.
Typical Applications
Depending on the equipment design, the Bussmann JJS-60 may be suitable for:
– Industrial electrical distribution
– Compatible power panelboards
– Electrical equipment branch circuits
– Variable-frequency drive line protection where specified
– Other installations designed for 60A Class T fuses
