    Surge Protection Devices

    The surge protection device (SPD) is an electronic device that provides security protection for various electronic devices, instrumentation and communication lines. SPDs play a role to restrict the transient overvoltage that enters the power line and signal transmission line to the voltage range that the device or system can withstand, or to discharge powerful lightning current into the ground, so as to protect the equipment or systems from strikes. Due to its role, surge protection device is suitable for surge protection in residential, tertiary industrial and other industrial applications.
    ATO offers a series of surge protection devices, Type 2 or Class II, DIN rail mount, with maximum discharge current 20kA, 40kA, 60kA, 80kA, 100kA, 120kA and 150kA for your choice, so as to meet your different requirements to protect your power system from the effects of lightning strike and transient overvoltage.
