0673001.DRT4 Circuit Protection

Introduction

The 0673001.DRT4 is a fuse designed to protect electrical and electronic equipment from over current situations due to circuit overloads or short circuits. It can be used both in DC and AC applications. This fuse is available in a wide range of amperage ratings and voltage ratings. The 0673001.DRT4 is UL Listed and is designed to meet UL Standard 4248.

Application Field

The 0673001.DRT4 is suitable for a variety of applications, including but not limited to: industrial machinery, data centers, medical equipment, computer/telecommunications systems, automotive systems, power supplies, motors, and generators. It is commonly used in renewable energy applications such as photovoltaic systems, wind turbines, and energy storage systems.

Working Principle

The 0673001.DRT4 is a thermal-magnetic fuse. It contains two separate components: a thermal element and a magnetic element. When a current exceeding the rated current passes through the fuse, the thermal element heats up due to the current flow. This heat causes a bimetallic strip to expand, exerting pressure on the arc plate that is connected to the fuse\'s contact points. This pressure causes the contact points to open, interrupting the circuit and protecting the downstream components from over current.

The fuse also contains a magnetic element, which is made up of a coil of wire and a magnetic core. When a higher than rated current flows through the fuse, it creates a magnetic field around the coil of wire. This magnetic field interacts with the core, creating a force which pushes the arc plate against the thermal element and further trips the fuse quicker than the thermal element alone.

Conclusion

The 0673001.DRT4 is a thermal-magnetic fuse designed to protect electrical and electronic components from over current situations. It is suitable for a wide variety of applications, and is designed to meet UL standard 4248. The 0673001.DRT4 contains both a thermal element, which trips the fuse when a current greater than the rated current flows through the fuse, and a magnetic element, which enhances protection by tripping the fuse quicker than the thermal element.
