10A 500V screw type fuse links has a filler closed tubular cap shape, with a rated working voltage of AC (50Hz) to 500V and a rated current of 125A. It mainly provides overload and short-circuit protection for electrical lines. It can also be derived from semiconductor devices and their complete set of short circuit protection (AR) and motor short circuit protection (AM). The rated breaking capacity of 10A 500V screen type fuse is 100kA. Welcome to buy.

Surge protective device (SPD) is a device used to protect electrical equipment and systems from overvoltage transients. 220-385v surge protective device can quickly limit the overvoltage to a safe range in case of transient overvoltage caused by lightning stroke, switch operation, start and stop of large electrical equipment in the power system, so as to protect the safe operation of electrical equipment.

Zhenghao 24V 10A Insulation Surge Protection is lightning protection in the field of process measurement and control, and provides signal protection for field equipment such as transmitter, thermal resistance, solenoid valve, flowmeter, valve positioner, frequency converter, etc.
Surge protection for i/o of control systems such as AI, Ao, Di, do and Pi of 24V 10A Insulation Surge Protection PLC. DCS。 It is widely used in petroleum, chemical industry, natural gas, environmental protection, new energy and other industries.
