Product description: Surge protection for AC 50 / 60HZ, failure of the product built from the device. When the surge protector overheating due to over-current, breakdown failure, failure from the device can automatically remove it from the power line, while visual warning indicator green (normal), red (fault), the module can have operating voltage Under replaced. Features: 1, built-in overcurrent overheating, temperature control circuit technology. 2, modular design, easy installation, can be replaced online. 3, the leakage current is small, fast response time, low residual voltage. 4, alarm indicating devices, green (normal), red (fault). 5, the core technology to produce high energy gap discharge electrode main technical parameters: Parameter 10KA Rated working power (V ~) 220V 380V maximum continuous operating voltage (V ~) 275V 385V Voltage Protection Level (V ~) KV ≤0.7 ≤1.0 Standard He said discharge current KA 5 maximum discharge current KA 10 response time <25 test basis GB18802, IEC61643-1 access wire cross-sectional area of ??L / N (mm2) 6 ??access grounding wire cross-sectional area of ??PE (mm2) 10 selected fuse or circuit breaker Type (A) 10A, 16A working environment -40 ℃ ~ + 85 ℃ Relative humidity ≤95% standard guide rail installation Standard Rail 35mm Housing material fiberglass Fiberglass Dimensions Illustration:
