Class J fuse
True Dual element fuses with minimum 10 second time delay at 500% overload
Dual element construction reduces power loss and gives cooler running
High breaking capacity: 300kA
Voltage rating 600Vac
High degree of current limitation due to fast speed of response to short circuits
Unique dimensions ensure that a different fuse cannot be substituted

Stock Nos. 513-0623 & 513-0718 have blade terminals

UL 248-8 Class J

UL Listed; CSA Certified

This time-delay T-speed fuse from Eaton is suitable for equipment that needs short-term power surges to do its job. The equipment will continue to operate and the slow-blow fuse will carry its overload for a short period. Its high breaking capacity means the body of the fuse can withstand short-term surges up to 300 kA at 600 V AC (10 kA at 300 V DC) without breaking. The fuse offers a minimum 10-second time delay in its response to inrush currents and responds quickly to short circuits.

• Dual element fuse construction offers cooler running and less power loss
• Fast response to short circuits, which limits overcurrent
• Unique dimensions of 1.06 x 2.38 inches ensure only the correct type of fuse can be inserted

Time-delay fuses are also called slow-blow fuses. They're typically used in the motor industry, as they can handle the high currents that pass through an electrical circuit when an engine is started without blowing.

Type T (or T-speed) fuses are extremely fast-acting fuses that can interrupt a minimum of 200,000 amps. They're commonly used for the circuit protection of devices such as inverters.
