The PTC Resettable Fuses, model B59607A0120A062, is a type of electrical safety device commonly used in production and electrical systems for various industries. It stands out among other electrical safety devices due to its innovative, self-resetting fuse feature. This feature allows the PTC Resettable Fuse to prevent overloading without having to be replaced; a simple reset is all that is required to restore full service to the electrical system. In this article, we will discuss the application field and working principle of the B59607A0120A062 PTC Resettable Fuse.

Application Field

The PTC Resettable Fuse is suitable for use in a wide variety of applications, from domestic to industrial. This type of fuse is particularly well-suited to electronic circuits that are exposed to vibration, shock, moisture, and temperature cycles. It is also highly reliable for use within electronic equipment that is subject to momentary overload conditions or start-up spikes. Typically, the PTC Resettable Fuse is used in the following applications;

• Household Appliances
• Audio and Video Equipment
• Home Theater Systems
• Automation Systems
• Medical Devices
• DC Power Supplies
• Telecommunications Equipment
• Uninterruptible Power Supplies (UPS)
• Battery-backup Systems

Working Principle

The working principle of the PTC Resettable Fuse is simple yet effective. The bimetallic element in the PTC Resettable Fuse is capable of detecting an overload current. When the fuse’s overall temperature exceeds a certain threshold, the element resistor reduces in resistance sufficiently to form a current limiting path to drop the voltage, thus preventing the circuit from consuming excessive current. The bimetallic element within the PTC Resettable Fuse is designed to ‘reset’ itself when the circuit\'s load is reduced and the fuse’s temperature is within normal operating range. This resetting restores the full-current capacity of the fuse and allows it to protect the circuit in the event of another overload situation. As with other fuses, however, the PTC Resettable Fuse will still ‘blow’ if there is an extreme overload. The PTC Resettable Fuse is also designed with an on-board diode which prevents the reversed current from entering the PTC Resettable Fuse if there is over-discharge from the load. This feature ensures that the fuse does not blow even if the polarity of the voltage source is reversed. The B59607A0120A062 PTC Resettable Fuse has a voltage operating range of 95 VAC to 265 VAC and can operate in temperatures from -40°C to +85°C. It has a current rating of 6.2A and a UL flammability rating of 94V-0. In summary, the B59607A0120A062 PTC Resettable Fuse is a reliable and highly effective safety device for protecting electronic equipment from overloads. Its innovative resetting feature saves both time and money by eliminating the need for replacement in the event of an overload situation. The wide range of applications and temperature rating, in addition to its other features, make it a reliable choice for numerous electronic systems.
