TJS40 - 40Amp Fuse

TJS40 - 40 Amp Fuse

The TJS40 is a 40 amp Class T fuse made for fast, reliable circuit protection in your commercial and industrial electrical systems. Its very fast-acting design helps clear fault conditions quickly, which can help reduce damage to connected equipment during overloads or short circuits. With a 200 kA interrupting rating at 600VAC, the TJS40 is commonly used in applications where high fault current protection is required. The compact cartridge-style body also makes it a good choice for panels and equipment where space is limited.

Built as a current-limiting fuse, the TJS40 helps reduce the amount of energy that passes through during a fault condition. That added level of protection is especially useful for sensitive electrical components, power distribution equipment, and control systems that need dependable overcurrent protection to stay running safely.
