Fuses

Fusing is the use of current limiting devices to protect electrical circuits from excessive currents. It is important to select the right type fuse for different applications. There are a variety of fuses available, each with its own unique characteristics and applications.

021606.3MXR8SPP Application Field and Working Principle

The 021606.3MXR8SPP is a fast-acting, single-pole, non-replaceable, time-delay fuse designed to protect both primary and secondary circuits. This type of fuse is commonly used in industrial control circuits, ac motors, transformers, and other similar applications. It is also suitable for use in parallel installation, and can be used to also protect downstrean fuses if the load current exceeds the fuse\'s rating.

The 021606.3MXR8SPP has a rated voltage of 600V AC/DC and a rated current of 40A. It is UL, CSA, and CE approved, and is RoHS compliant. This type of fuse includes a tin-plated copper body and a copper contacting element. It also has a ferric oxide arc-quenching element, which prevents infinite current flow and limits the current to the rated current. The fuse has an operating temperature range of -50°C to 125°C and a maximum melting current of 0.2 times its rated current.

The 021606.3MXR8SPP works by melting at a specified operating time when the current flowing through it exceeds its rated value. As the temperature rises, the fuse element will eventually melt and break the circuit, thus preventing further damage from excess current. It also serves to protect other downstream devices from overload by providing a built-in safety feature.

The 021606.3MXR8SPP can be used for a wide range of applications, including industrial control circuits, ac motors, transformers, and other similar applications. It is also suitable for use in parallel installation, and can be used to also protect downstrean fuses if the load current exceeds the fuse\'s rating. With its excellent thermal-mechanical stability and low melting current, this type of fuse is an effective and reliable solution for protecting your equipment.
