• Transient overvoltage protection: Diverts overvoltages from lightning strikes, power grid switching, or equipment faults to ground, protecting sensitive components and preventing downtime in industrial plants, commercial buildings, and data centers.
• System integration: Installed at incoming line end (Type 1 SPD) or downstream distribution points (Type 2 SPD), working with overcurrent protection devices to prevent false tripping.
• Enhanced reliability: Multi-stage surge protectors (Type 1 + Type 2) provide layered protection for critical applications like medical facilities and telecommunications hubs.

• Material: Galvanized sheet or other steel
• Color: Grey
• Protection Level: IP55
• Type: Distribution Electric Control Enclosure
• Shell Thickness: Door panel 2.0mm, box body 1.5mm, installation plate 2.5mm
• Rated Voltage: Medium and low voltage
• Rated Current: 63A - 630A

IP30, IP40, IP55, IP65

• Type selection: Use Type 1 SPDs (Imax ≥ 15kA) for outdoor incoming line cabinets and Type 2 SPDs (In ≥ 5kA) for indoor load side. Combine Type 1 + Type 2 for critical applications.
• Installation: Maintain ≤5m distance from main circuit breaker, connect 100A/10kA fuse at incoming line, and add decoupling inductor for sensitive equipment.
• Material selection: 304 stainless steel shell (IP65) with anti-salt spray coating for coastal areas, tinned silver copper terminals (≥160A current-carrying capacity).
• Enhanced functionality: Remote signaling interface for SPD status monitoring and thermal backup module for automatic failure protection.
