RTE190

PTC resettable fuses, or Positive Temperature Coefficient Resettable Fuses, are device components that are designed to protect electric devices and circuits by cutting off electric current when an overload is detected. This type of fuse, usually made of thermoplastic material, contains a thin resistor that’s designed to begin sweltering and trip the circuit in the event of a current overload. RTE190 is a PTC resettable fuse that has made a big development in the world of circuit protection for many industries.

RTE190 was developed as a result of extensive research conducted by specialists in the field of electrical protection. It has a wide range of applications and is suitable for use in electric devices such as: service panels, computers, and TV and audio equipment.

RTE190’s most notable attributes include the following:

• Wide range of current ratings
• High surge withstand ability
• High inrush-withstanding current
• High response speed
• High terminal temperature

The working principle of the RTE190 is simple. As long as the current is within the operating range of the fuse, it will operate normally. If the current increases beyond the operating range, then the internal resistor will start to heat up and eventually melt, causing the fuse to trip and cut off the current to protect the circuit.

The RTE190 also features a resettable element that allows it to be reset after it has tripped. The resettable element is a small disc made from a special material that expands when heated, causing the fuse to reset and allowing current to flow again. This resettable element helps make the RTE190 a more reliable protection device compared to other fuses as the device can be reset easily without having to be replaced.

The RTE190 is copper and aluminium alloy base which ensures high conductivity and reduces power losses. Its terminals are also insulated to prevent shorts and to ensure its protection against electrocution. It is also designed to meet international standards such as UL and CSA regulations, so users can rest assured that it provides the highest protection to their circuits.

RTE190 has a wide range of application fields ranging from Automotive, Medical, Telecommunications, Industrial Automation as well as consumer electronics. It can be used both for AC and DC type circuits.

In conclusion, RTE190 is an efficient and reliable PTC resettable fuse that has a wide range of applications and provides users with a higher level of protection compared to other fuses. It is also easy to reset and meets international safety standards, making it an ideal choice for any circuits.
