TVSS (Transient Voltage Surge Suppressor) is a core member of the surge protector (SPD) family that deals specifically with transient overvoltages. The HM400(200)B3N is designed for three-phase power systems, setting a new standard in industry protection.
HM400B3N
The product design strictly follows top global safety norms, ensuring safety protection in high-demand scenarios such as industrial, energy, and communication fields according to international and domestic standards:
International Standard: IEC 61643 (International Standard for Surge Protection)
North American Safety: UL 1449 (US Safety Certification)
Chinese National Standard: GB/T 18802 (Chinese Surge Protector Standard)
Communication Norm: YD/T 5098 (Telecom Industry Lightning Protection Norm)
Strong Voltage Endurance: Maximum continuous operating voltage 385VAC (L-N) / 770VAC (L-L), easily coping with grid fluctuations.
Direct Lightning Defense: 25KA maximum impulse current (10/350μs), effectively resisting direct lightning energy.
Precise Clamping: ≤1.4kV residual voltage (L-N), firmly limiting overvoltage within the safe threshold of the equipment.
High Current Flow: Core advantage! The current capacity reaches up to 400KA (8/20μs), providing military-grade surge discharge capability.
Dual Insurance
Thermal cut-off protection + failure sound and light alarm, instant fault alarm, eliminating "silent failure", automatically cutting off the degraded circuit, eliminating leakage and fire hazards.
Visual Status
The panel integrates three-color indicator lights (power-green / protection-yellow / failure-red), making operating status clear at a glance.
Sturdy and Durable
Copper-plated aluminum alloy shell, IP54 protection level (dustproof and waterproof), suitable for extreme environments from -40℃ to +85℃.
Easy Maintenance
Modular design, no need for regular internal component checks, just observe the panel indicator lights, greatly reducing maintenance costs and complexity.
Crucial projects such as domestic banking data centers, securities data centers, and civil aviation craft installations all require the highest level of protection according to design standards, using TVSS. The HM series product line comprehensively covers various levels of lightning protection needs:
Level 1 Protection: 400KA (8/20μs)
Level 2 Protection: 200KA (8/20μs)
Level 3 Protection: 100KA (8/20μs)
