保護器是一種裝置，主要用于保護電器設備免受過載、過流、短路等電氣故障的影響。

• Translation: A protector is a device that is mainly used to protect electrical equipment from electrical faults such as overload, overcurrent, and short circuit.

它能夠在電器遭遇瞬間電壓的異常情況下智能啟動內部保護裝置，確保后端用電器的用電安全。

• Translation: It can intelligently activate internal protection mechanisms in the event of an instantaneous high voltage anomaly in electrical equipment, ensuring the safety of the downstream electrical appliances.

保護器可以根據不同的需求選擇，分為家用保護器和機械之類的保護器。

• Translation: Protectors can be selected based on different needs, including household protectors and protectors for machinery and similar equipment.

電子儀器和電動機保護器則提供更具體的保護，如給電機全面的保護控制，在電機出現過流、欠流、斷相、堵轉、短路等情況時予以報警或保護控制。

• Translation: Electronic instrument and motor protectors provide more specific protection, such as comprehensive protection and control for motors, and provide alarms or protective control in the event of motor overcurrent, undercurrent, phase loss, stalling, short circuit, and other conditions.

電器保護器，又稱過壓保護器、壓保護器、家電保護器，保護各類電器不被壓或低壓燒壞，當供電電源出現浪涌、電壓不穩等問題時，立即斷開電源，避免電器設備被燒毀以及電器火災的發生。

• Translation: Electrical protectors, also known as overvoltage protectors, high-voltage protectors, and household electrical protectors, protect various electrical appliances from being damaged by high or low voltage. When issues such as power supply surges or unstable voltage occur, they immediately disconnect the power supply to prevent electrical equipment from being burned out and electrical fires from occurring.

漏電保護器，簡稱漏電開關，用于在設備發生漏電故障時及時斷電，保護線路或電動機的過載和短路，也可在正常情況下作為線路的不頻繁轉換啟動之用。

• Translation: A leakage protector, also known as a leakage switch, is used to promptly disconnect the power supply when a leakage fault occurs in the equipment, protecting the line or motor from overload and short circuit. It can also be used for infrequent switching and starting of the line under normal conditions.

浪涌保護器，也叫防雷器，為各種電子設備、儀器儀表、通訊線路提供安全防護，防止浪涌對回路中其他設備的損害。

• Translation: A surge protector, also known as a lightning arrester, provides safety protection for various electronic devices, instruments, and communication lines, preventing surges from damaging other equipment in the circuit.

保護器的種類還包括過載保護器和過流保護器，它們能夠避免電氣設備因為長時間運行而超載或過流而發生損壞。

• Translation: The types of protectors also include overload protectors and overcurrent protectors, which can prevent electrical equipment from being damaged due to overload or overcurrent caused by prolonged operation.
