Product Description
Induced lightning surges and grid switching transients often burn industrial mainboards, inverters and building low-voltage hardware. This 4-pole three-phase SPD acts as secondary protection in LPZ0B-LPZ1 cabinets, conducting and diverting surge currents within 25ns to clamp residual voltage to safe ranges and reduce overvoltage breakdown risks for downstream electronics. 40kA maximum discharge capacity withstands repeated heavy lightning impulses; anti-vibration modular design fits long-running cabinets, and built-in thermal release prevents secondary overheating hazards from failed modules. Visible fault indicators allow timely replacement to cut equipment downtime and repair costs.
Key Features
≤25ns ultra-fast response instantly blocks lightning voltage spikes
40kA surge capacity retains protection performance after multiple lightning strikes
Full L-N & N-E discharge paths cover all phase surge routes
Automatic thermal disconnection eliminates overheating risks from faulty modules
Dual status monitoring identifies degraded units in advance
FAQ:
Q1: Will SPD installation fully eliminate lightning-caused equipment damage?
A: This secondary LPZ Type 2 unit drastically reduces failure risks when cascaded with Type 1 primary arresters, but cannot fully block ultra-high energy direct lightning strikes.
Q2: If equipment burned frequently during thunderstorms in previous years, will higher-rated SPD improve performance?
A: Select matching Uc model per site mains voltage; 40kA surge capacity enhances heavy transient diversion, and coordinated multi-stage lightning protection optimizes overall safety.
Q3: What risks exist if degraded failed modules are not replaced?
A: Failed modules lose surge diversion capability, passing full lightning impulse voltage directly to downstream equipment and increasing burnout probability.
