TVSS SPD (Transient Voltage Surge Suppressor) protects low-voltage three-phase power systems from damaging voltage spikes. You can install it at the LPZ 0A-2 boundary or higher. It effectively safeguards sensitive equipment from transient overvoltages. This device supports SPD Class I + II (Type 1 + 2 / Class B + C). It meets IEC 61643-11 and UL 1449 4th edition standards. The suppressor quickly reduces surge energy, enhancing system safety and extending equipment life.
Features
1. High Surge Current Capacity – Handles large transient surges from lightning and switching events.2. Three-Phase Protection – Designed for three-phase 3W+G power systems.
3. Fast Response Time – Reacts within nanoseconds to suppress voltage spikes instantly.
4. Combined Type 4-1 SPD – Offers both Type 1 and Type 2 protection in a single device.
5. LED Status Indicators – Provides easy visual monitoring of device status and faults.
6. Compact DIN Rail Mounting – Space-saving design for quick and secure installation.
7. Thermal Disconnection Technology – Prevents overheating and enhances operational safety.
8. Standards Compliant – Manufactured according to IEC 61643-11 and UL 1449 4th edition standards.
Advantages
1. Minimizes Equipment Failures – Helps avoid costly downtime caused by surge-related damage.2. Lowers Maintenance Costs – Reduces the frequency and expense of repairs over time.
3. Increases System Reliability – Ensures stable operation even during power fluctuations.
4. Protects Investment – Safeguards critical infrastructure and sensitive electronics.
5. Enhances Worker Safety – Decreases risk of electrical hazards in the workplace.
6. Simplifies Compliance – Makes meeting electrical safety regulations easier.
7. Saves Energy – Prevents inefficiencies caused by transient voltages.
8. Provides Peace of Mind – Offers confidence that equipment is shielded from unpredictable surges.
