Technical Specifications Device Type: Power System Surge Protective Module Nominal Discharge Current: According to TGT‑S00N series standard parameter System Applicable Voltage: Low‑voltage AC power system Connection Mode: Parallel connection to power circuit Operating Temperature: ‑40 °C to +80 °C Storage Temperature: ‑40 °C to +85 °C Relative Humidity: 5%‑95%, non‑condensing Mounting: 35 mm DIN‑rail mounting Certifications: CE surge protection device compliance
Functional Features Absorbs transient lightning surge and switching over‑voltage energy on power lines. Clamps surge voltage within safe range for downstream load equipment. Built‑in thermal disconnection safety structure to prevent component fire risk under failure condition. Supports modular plug‑in structure for quick replacement without modifying main circuit wiring.
Application Scenarios Mainly deployed in industrial automation control cabinets, communication power supply cabinets, factory building power distribution boxes. It provides surge protection for PLC systems, instrument power supply and precision industrial control equipment.
Structural Characteristics Plastic insulating modular housing with DIN‑rail buckle at bottom. Spring‑type wiring terminals for fast power circuit connection. Internal integrated surge absorption core component and thermal disconnect assembly.
Working Principle Under normal power‑grid working condition, the module keeps high‑impedance state and does not affect normal power supply. When transient surge over‑voltage appears on power line, internal core component instantly converts to low‑impedance state, absorbs surge energy and limits voltage amplitude, so as to protect rear‑end electrical equipment.
Installation Requirements Mount module on standard 35 mm DIN‑rail inside control cabinet. Connect the module in parallel to L‑N or L‑PE loop strictly following official wiring schematic. Minimize wiring length for surge protection loop to reduce residual surge voltage. Confirm wiring correctness before power‑on operation.
Usage Notes Select correct voltage grade matching local power grid voltage. Check module status indicator regularly during operation. Replace module promptly after surge failure indication appears.
