SPD Surge Protectors for Low-Voltage Enclosures Transient Overvoltage Shield
Product Describe:
• Protection against transient overvoltage: In low-voltage switchgear, surge protectors (SPDs) can divert transient overvoltages caused by lightning strikes, power grid switching, or equipment faults to the ground. This protects sensitive components such as circuit breakers, contactors, and meters from damage, and avoids downtime in industrial plants, commercial buildings, or data centers.
• Integration with system design: Surge protectors are installed at the incoming line end (Type 1 SPD) or downstream distribution points (Type 2 SPD), and work in coordination with overcurrent protection devices to prevent false tripping. For example, in factory switchgear that supplies power to motors or automation systems, surge protectors can limit voltage spikes to ≤2.5kV, ensuring the stable operation of programmable logic controllers (PLCs) and frequency converters.
• Enhancement of system reliability: In critical application scenarios (such as medical facilities, telecommunications hubs), multi-stage surge protectors (Type 1 + Type 2) can provide layered protection.
