1000VDC T2 Surge Protective Device with 40kA Maximum Discharge Capacity
Key Features and Advantages
The device offers a standardized discharge current of 20kA, demonstrating consistent performance under repeated surge conditions. Its T2 classification indicates compliance with international standards for surge protection equipment, specifically designed to handle indirect lightning effects and switching surges in electrical distribution systems. The 1000VDC rating makes it suitable for various highvoltage DC applications where reliable surge protection is required.
The integrated thermal protection mechanism automatically disconnects the unit during overload conditions or at endoflife failure, ensuring system safety. A visual status indicator provides clear operational feedback through colorcoded display, enabling quick assessment of the device's condition. DIN rail mounting facilitates easy installation in standard electrical enclosures, while screw terminal connections ensure secure wiring implementation.
Application Scenarios
This protective device is primarily used in photovoltaic systems for protecting solar inverters, combiner boxes, and monitoring equipment from lightninginduced surges. Industrial applications include protection for motor drives, control systems, and automation equipment in manufacturing environments. The unit is also suitable for electric vehicle charging infrastructure, telecommunications power systems, and backup power installations where DC power protection is required.
Additional applications include railway electrification systems, mining equipment, and other industrial settings where electrical systems are exposed to potential surge events. The device provides effective protection for both indoor and sheltered outdoor applications when installed in appropriate enclosures.
