6421-2T Application Field and Working Principle
The 6421-2T is a thermal time-delay fuse specially designed for protecting sensitive automotive, industrial, and consumer electronic components from overcurrent and fault conditions. It features a temperature-responsive element that delays activation during short circuit and start-up conditions, allowing hard-start motors, compressors, inductive loads, or other components with large inrush currents to start up safely and without significant tripping.
Applications
The 6421-2T is a small, 6.3 amp time-delay fuse designed primarily for automotive applications. It is used to protect sensitive automotive electrical components from overcurrent and fault conditions, including those resulting from thermal overload, short circuit, leakage, and surge. It is also suitable for protecting starter motors and other circuit components with large starting current.
The 6421-2T is also suitable for industrial and consumer electronic applications where overcurrent and fault protection is needed. It can be used to protect motors, compressors, and other inductive loads, as well as a variety of other circuit components.
Working Principle
The 6421-2T is a thermal time-delay fuse. It features a temperature-responsive element that delays activation during short circuit and start-up conditions, allowing hard-start motors, compressors, inductive loads, or other components with large inrush currents to start up safely and without significant tripping. This temperature-sensitive element also allows for temperature-compensated operation over a wide range of ambient temperatures.
In normal conditions, current flowing through the fuse will generate heat along the element. When the current rating is exceeded, the heat generated will increase and cause the element to expand. This causes the contact points to separate, which breaks the circuit and trips the fuse. The time it takes for this process to occur is the time-delay.
Advantages
The 6421-2T offers several advantages, including:
- High inrush current capacity
- Temperature-compensated operation
- Robust electric arc suppression
- UL Recognized, CSA certified, VDE approved
- Improved safety and reliability
