PTC Resettable Fuses

PTC resettable fuses are an alternative to traditional fuse technology. They are designed to reduce the risk of surge overloads on electrical systems, allowing time periods to reset without the need to replace blown-out fuse units. By using a current limiting resistor in the fuse, the PTC resettable fuse automatically responds to current overloads and shuts off the power, giving a user more protection when dealing with electrical systems.

VLP270XXUF is a series of PTC resettable fuses, designed to protect circuits, equipment and components in high-voltage applications. The fuse is a two-part construction unit with an integrated overcurrent protection element. The circuit is made up of a molded body and a PVC insulated terminal block, which is connected to the body of the fuse. The VLP270XXUF is an ideal choice for applications requiring maximum surge current protection, such as high voltage power supplies, power management, automotive, consumer electronics, lighting and motor control.

VLP270XXUF Application Field and Working Principle

The VLP270XXUF has a wide range of application fields. It is suitable for use in applications that require protection against over-current, and its resistance to reverse surge current allows its use in high-voltage environments. Additionally, the fuse has a high DC voltage tolerance, making it suitable for applications with a wide range of power supplies. The fuse is also capable of carrying both AC and DC load current, making it ideal for use in various current-requiring systems.

The operating principle of the VLP270XXUF is quite simple. The resistor element in the fuse limits the current passing through it, causing it to heat up until the fuse melts the resistor element, and the circuit is reset. This resetting process is done without any intervention from the user, as the PTC Resettable Fuse will reset itself when the power supply is turned off or high-voltage surge overloads occur.

As the VLP270XXUF is a two-part construction unit, it can be easily installed and removed. The fuse can simply be disconnected from the circuit and replaced with a new one, allowing for easier maintenance and repair. Additionally, the low resistance of the fuse ensures that the fuse will reset quickly, allowing for faster recovery times in the event of an over-current situation.

The VLP270XXUF has a wide range of advantages when compared to traditional fuse technology. In addition to providing increased protection in the event of surge overloads, the PTC Resettable Fuse is significantly less expensive than traditional fuse technology, simplifying installation and maintenance. Additionally, the fuse is capable of providing better protection than traditional fuse technology, as the circuit can be reset quickly and easily, reducing the risk of long-term damage to electrical systems.

The VLP270XXUF is an excellent choice for applications requiring robust surge and overload protection. The PTC Resettable Fuse provides excellent safety features, allowing users to reduce the potential for equipment failure in high-voltage environments. It is also a cost-effective solution, simplifying installation and maintenance, while providing greater protection against over-current and reverse surge conditions.
