Fuses are devices used to protect electrical circuits from overloads and short circuits. They are generally made up of a fusible element, a circuit breaker, and a circuit protector. The main purpose of a fuse is to limit the amount of current and/or voltage that can pass through the protected circuit. When a specific predetermined level of current or voltage is reached, the fuse will blow and interrupt the current flow.

046001.5UR is a current-limiting fuse used to protect circuits from short circuits and overloads. It is a Time Delay Fuse which provides highly reliable motor and general feeder short-circuit and overload protection. This type of fuse has an interrupt rating of 65kA at 600V and 125kA at 250V. The 046001.5UR is Class RK1 time delayed to reduce nuisance opening from momentary overloads.

The 046001.5UR is suitable for a broad range of applications, such as branch circuits, motor branch circuits, machines, and other general-purpose circuits. It is commonly used in residential, commercial, and industrial settings. It can also be used in larger industrial installations to protect higher voltage circuits and motors from overloads and short circuits.

The working principle of the 046001.5UR is based on the melting of a fusible element, which is typically a small metal wire or ribbon. When the current passing through the circuit reaches the preset level, the fusible element melts, interrupting the current flow. The interruption of current is determined by the melting time of the fusible element.

The 046001.5UR fuse also features an overload protection. An overload occurs when the current flowing through the circuit is greater than the normal operating value. In this case, the fuse will open and interrupt the current in order to protect the circuit from damage.

The 046001.5UR fuse is also a Class RK1 Time Delay Fuse, which is specifically designed for motor branch circuits and other general-purpose circuits. This type of fuse features a specifically designed melting element that can withstand momentary overloads and motor starting inrush currents. This prevents nuisance opening while the system or motor is in operation.

In summary, the 046001.5UR fuse is a current-limiting fuse used to protect circuits from short circuits and overloads. It is suitable for branch circuits, motor branch circuits, machines, and other general-purpose circuits and is commonly used in residential, commercial, and industrial settings. It features a melting fusible element, overload protection, and the Class RK1 time delay which prevents nuisance openings due to momentary overloads.
