0434002.NRP Datasheet/PDFFuses are one of the most important components in electrical systems. They are designed to protect electrical circuits from damage due to faults or excessive currents. The 0434002.NRP type fuse provides a reliable and cost-effective solution for applications in low to medium voltage systems.
Application Field
The 0434002.NRP is a cartridge type fuse suitable for use in low to medium voltage systems. It is UL 248-13 recognized and CSA certified and is suitable for use in industrial, commercial and residential applications. It is designed for use with both single-phase and three-phase loads. Typical applications include protection of lighting and control circuits, air conditioning systems, motor control circuits, and other loads with similar characteristics.
Working Principle
The 0434002.NRP fuse works by limiting the flow of current through it. When the current exceeds a certain predetermined value, the fuse will "blow", interrupting the flow of current and protecting the circuit. The current rating is usually marked on the fuse. When the fuse "blows" it must be replaced with another fuse with the same current rating.
The 0434002.NRP fuse features a dual-element construction with an individually selectable time-delay, rated from 5A to 6A. This time-delay feature provides additional time to allow circuitry to shut off prior to the fuse "blowing", thus further reducing the risks of damage to components in the system. The fuse also features an instantaneous trip element which will instantly open if the current exceeds the pre-determined limit.
Conclusion
The 0434002.NRP fuse is a highly reliable and cost-effective solution for protecting circuits in low to medium voltage applications. Its dual-element design and selectable time-delay feature provide additional protection against damage caused by sudden short-circuits or surges. The fuse must be replaced with an identical fuse of the same current rating to ensure maximum protection of the circuit.
