PTC Resettable Fuses, also known as polymeric positive temperature coefficient (PPTC) resettable fuses, are over current protection devices designed to protect electronic circuits from damage due to excessive current. They are based on a circuit breaker mechanism that allows the circuit to reset after it has been over current. The protection devices can be triggered manually or automatically, depending on the application.

The 600R150-RBZR is a type of PTC Resettable Fuse that is designed for high-current applications. It is built into a standard 600 A/B/C size package, making it ideal for use in a variety of applications. This device is capable of interrupting up to 4 KA of AC and DC current. It is designed with an adjustable trip current range of 130 to 160 Amps, with an unadjusted trip current of 150 Amps. The time delay is adjustable from 0.2 to 3 seconds.

600R150-RBZR application fields include motor control, AC and DC switching power supplies, and other high current applications such as battery and charger applications. In addition, this device can be used in various telecommunications, automotive, consumer electronics, and medical equipment.

The working principle of the 600R150-RBZR PTC Resettable Fuse is simple and reliable. It uses a positive temperature coefficient (PTC) thermistor to detect over current. When current is greater than the device’s set current, the temperature rises due to Joule effect, which causes the PTC to increase its resistance drastically until the current is limited. When the current is decreased to the set current, the PTC thermistor cools down and the resistance decreases, allowing current to flow again.

The 600R150-RBZR PTC Resettable Fuse provides reliable over current protection for a variety of applications. It is easy to install and has an adjustable trip current range for easy setting. The device is also very reliable and offers fast, reliable over current detection.
