Fuses have been a popular choice of protection for loads for many decades. The 0454007.MR fuse is a current limiting fuse intended for use in applications ranging from short-term current limiting to secondary protection in various industries, including industrial, commercial, military, and telecom. This article will discuss the application field and working principle of this particular type of fuse.

The 0454007.MR fuse is a UL-listed, current limit, tray-mount Fusionetics™ Series fuses with a 200A rating and a voltage range of up to 350 Vac. This type of fuse is suitable for short-circuit protection in branch-circuit applications. Its construction allows it to protect against arc faults while limiting the amount of current delivered to the load. It is suitable for use in environments with up to 300V surge protection.

The 0454007.MR fuse is UL-recognized for AC application up to 300V and DC application up to 250V. It can be used in a variety of residential, commercial, industrial, and fixed medical equipment applications. It is suitable for many types of motors, lighting, pumps, HVAC, appliance, heating, air conditioning, refrigeration, vending, and communication circuits.

The working principle of a 0454007.MR fuse is relatively simple. The fuse is a current-limiting device designed to provide protection against overloads and short circuits. When the current passing through it exceeds its rated current value, the fuse melts, interrupting the circuit and preventing a dangerous overload condition. The trip time of the fuse ranges from 300-5000A, and the time delay rating for this particular model is 1-1.5 minutes.

In summary, the 0454007.MR fuse is a current-limit, tray-mount Fusionetics™ Series fuse with a 200A rating and a voltage range of up to 350 Vac. It is UL-recognized for AC and DC applications up to 300V and 250V respectively, making it suitable for a variety of residential, commercial, industrial, and fixed medical equipment applications. It is designed to provide protection against overloads and short circuits, with a trip time ranging from 300-5000A and a time delay rating of 1-1.5 minutes.
