Fuses

The 0230001.DRT3W electrical device is a fuse manufactured and distributed by the nVent Thermal Management company. It is a Class CC type of fuse, used in low voltage applications, usually between 12 and 48 volts. The 0230001.DRT3W can be used in applications such as HVAC systems and similar industries requiring reliable and safe electrical systems.

Application Field

The 0230001.DRT3W fuse is a Class CC type of fuse rated at 32 volts and 20A. This type of fuse is commonly used in low voltage applications, typically used in many HVAC systems, as well as in other appliances and equipment that require reliable and secure electrical power. This fuse has a quick-acting circuit-breaking action when overcurrent occurs, to protect the circuit from short-circuits or overvoltage conditions.

Working Principle

The 0230001.DRT3W fuse operates on the principle of a thermal/time delay device. The fuse is rated to prevent current passing though the device at 20A or greater for a period of at least 10 seconds. This time-delay fuse construction is designed to provide more time than the standard straight-acting breakers or fuses, and to provide some time for the power circuit to reset properly before it shuts down.

When too much current passes through the fuse, a high resistance element inside it heats up. As the heat increases, the resistance of the metal filament inside the fuse also increases, causing the temperature to rise further. Once the heat reaches a critical level, the fuse is designed to open the circuit, thus preventing the excessive current from passing through the device. The amount of time taken for this cycle to complete is a critical factor for its proper functioning, and that is why the 0230001.DRT3W has been designed with a time delay feature.

Conclusion

The 0230001.DRT3W is designed to provide a reliable medium to protect the electronic and electrical system from over-current, over-voltage, and short-circuit conditions, in the voltage range of 12 to 48 volts. Its thermal/time delay capabilities help to protect the system from any sudden short-circuit or over-voltage conditions, letting the circuit safely reset itself before closing down.
