RUEF400-AP Circuit Protection

PTC resettable fuses, or polymeric positive temperature coefficient (PPTC) fuses, are protective devices that protect circuits from current that is too high or too low. The RUEF400-AP is a type of resettable fuse designed for automotive applications. It is a reliable, cost-effective solution for line and load protection.

The RUEF400-AP is designed to shield circuits from overcurrent and overvoltage. It can be used in automotive and other harsh environments, such as the automotive and industrial markets. The RUEF400-AP is also UL recognized, meaning it meets safety standards.

The RUEF400-AP has a number of features that make it ideal for automotive applications. It has a high current rating of 400A, a low holding current of 24A, and a maximum operating temperature of +125°C. It also has a fast response time, which helps protect circuits from electric shock or fire hazards.

The RUEF400-AP features a special anti-vibration gel material, which helps it remain stable under high vibration conditions. This makes it suitable for automotive applications. The RUEF400-AP also has a low-profile design and a snap-in mounting option, making it easy to install.

The RUEF400-AP works in a particular way, depending on the current that is flowing through it. When the current is within a safe range, it will remain in its open state and allow current to flow through the circuit. However, if the current flowing through it exceeds its set current rating, the fuse will trip and open the circuit, preventing further damage to it.

Once the circuit is open, the current in the circuit will not be able to flow through the fuse and it will remain in its open state until the current is reduced. When the current falls back within safe limits, the fuse will automatically reset and the circuit will be closed again. This process helps protect circuits from excessive current, preventing both damage and safety hazards.

The RUEF400-AP is a reliable and cost-effective solution for line and load protection in automotive and other harsh environments. Its fast response time, anti-vibration gel material, and low-profile design make it well suited for automotive applications. Its ability to trip and reset based on the current that is flowing through it helps protect circuits from electrical shock or fire hazards and ensures the safe operation of automotive systems.
