BUSSMANN JJS-400 Very Fast Acting Fuse, 400 A, 600 V, Current Limiting

Bussmann JJS-400 Class-T fuse is ideal for safeguarding electrical circuits and equipment from excessive current levels. Its Class-T designation signifies its fast-acting nature, providing quick response to short-circuit and overload conditions and preventing potential damage & downtime. It is used in industrial machinery, power distribution panels, renewable energy systems and data centres.

• When the current passing through the fuse exceeds its rated value due to an overload or short circuit, the fuse starts to respond.
• The high current causes the fuse element inside to heat up rapidly.
• As the temperature of the fuse element rises, it reaches a critical point where the element melts or breaks, creating an open circuit.
• This interruption in the circuit disconnects the faulty or overloaded section from the power source.
• The interruption prevents excessive current from flowing, protecting connected equipment and preventing damage or hazards.
• After the fuse element breaks, the fuse needs to be replaced to restore the circuit's functionality, making maintenance straightforward.

• This Class T, fast-acting fuse provides reliable protection against short-circuit & overload conditions in electrical circuits.
• It has a holder-based mounting design for easy installation.
• This industrial power fuse features a cartridge blade style, protection against overloads and short circuits in high-power industrial applications.
• It has an interrupt rating of 200kAIC.
• This fast blow fuse features a knife blade termination style for secure connections.
