Fuses are widely used components used to protect electric circuits that are periodically exposed to over-current or short-circuit faults. This article provides an overview of the 021506.3MXP application field and its working principle.

Application Field

The 021506.3MXP is a small periodic AC and DC fuse suitable for types ranging from 0.2 to 32A. It can be widely used life and non-life support electric circuits in automobiles, motorcycles, electrical control cabinets, motor and lighting circuits, micro-motor control of small household appliances, electronic circuits, external power supply, indicator light, instrument, and other industrial control systems.

Working Principle

The 021506.3MXP fuse consists of a metal body, an arc-cutting part, an inner container, and a contact component. When the circuit is overloaded by an electric current, the contact component will become overheated and expand, making physical contact with the inner container and forming an arc. The arc rapidly melts the fuse element, which in turn quickly opens the circuit and protects the electric circuit.

The 021506.3MXP has an additional temperature sensitive element which expands in the case of an over-current and helps to terminate the circuit more quickly. This ensures that any potential over-current situation is quickly dealt with and prevents further damage to the circuit.

The time taken to open a circuit is very important, as it could be the difference between preventing damage to an appliance or not. The 021506.3MXP is designed with a very fast operating time of less than 3 milliseconds, meaning that any over-current situation is dealt with quickly and effectively.

As well as being designed with a fast operating time, the 021506.3MXP also features a high endurance and breaking capacity which can withstand up to DC 500V, 10kA and AC 500V between 1 to 10kA short-circuit capacity.

Conclusion

The 021506.3MXP is a small periodic AC and DC fuse suitable for types ranging from 0.2 to 32A.It has a quick operating time, high endurance, and breaking capacity, making it an ideal choice for a range of electrical control cabinet, motor and lighting circuits, households appliances and other industrial control systems.
