Product Description
4-pole Type 2 SPD engineered for three-phase industrial automation cabinets, installed in LPZ0B-LPZ1 secondary lightning zones to protect PLCs, inverters and servo systems from lightning surges and grid switching transient overvoltage. Full L1/L2/L3-N-E circuit diverts surge currents with ≤25ns fast response to clamp dangerous high voltage. Operating temperature range -40℃ to +70℃ fits cold workshops and hot equipment rooms, anti-vibration modular design withstands continuous production line vibration. Built-in low-temperature thermal release avoids fire risks from failed modules, while green/red status window plus remote contacts connect to automation monitoring platforms for dual local & remote status tracking.
Key Features
Ultra-fast ≤25ns response blocks transient voltage spikes on automation hardware
40kA surge capacity handles frequent lightning transients in industrial zones
Vibration-resistant modules for continuously vibrating production cabinets
Wide temperature tolerance for cold workshops and high-heat equipment rooms
Dual fault monitoring compatible with remote industrial operation systems
FAQ:
Q1: Can it suppress switching surges generated by frequent production line start-stop?
A: The SPD is tested per 8/20μs waveform for grid operation transients, capable of diverting regular switching impulse currents continuously.
Q2: Do multiple inverters in one cabinet require extra SPD units?
A: A single 4P SPD protects the main three-phase incoming line; additional Type 3 SPDs can be installed on branch circuits for coordinated protection.
Q3: Will false tripping occur in cold workshop winter environments?
A: Specialized ultra-low temperature thermal release prevents unnecessary disconnection at -40℃ ambient.
