Product Description Type 2 surge protective device exclusively designed for 440Vac high-voltage three-phase distribution systems, installed in heavy-duty industrial control cabinets and large commercial secondary panels within LPZ0B-LPZ1 zones. It diverts lightning and grid switching surges with voltage protection level ≤ 2.0kV to safeguard large inverters and power control cabinets. 4-pole full L1/L2/L3/N-E circuit protection with 40kA maximum discharge capacity handles

Product Description Laboratory precision measuring instruments are highly sensitive to voltage fluctuations and lightning surges; transient high voltage causes sensor calibration drift and permanent circuit damage. This 4-pole Type 2 SPD is installed on lab three-phase incoming distribution panels. The low voltage variant delivers residual voltage as low as ≤ 1.25kV with ≤ 25ns nanosecond-level response to divert surge currents and contain impulse voltage within instrument

Product Description Integrated non-detachable SPDs require full removal and complete rewiring upon failure, increasing maintenance time and loose wiring risks. This SPD adopts split base + independent pluggable module structure: when one module degrades, only the faulty unit needs extraction and replacement with all base, phase and PE wiring untouched to cut on-site wiring labor. Anti-loose locking buckles resist long-term cabinet vibration, while each single module
