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 safe tolerance ranges. Wide humidity tolerance fits constant temperature & humidity lab environments, remote contacts feed fault alerts to central lab control systems for unattended operation safety, and pluggable modules simplify maintenance without full lab power shutdown. TUV & CE certification meets procurement standards for international research laboratory projects.
Key Features

FAQ:
Q1: Do single-phase precision instruments require separate single-pole SPDs?
A: This 4P main SPD protects lab three-phase incoming power; supplementary single-phase Type 3 SPDs are recommended at individual instrument terminals for fine protection.
Q2: Can SPD failure trigger automatic alerts during unattended overnight lab operation?
A: Remote signalling contacts connect to lab central control or IoT gateways to push fault notifications to back-end monitoring platforms.
Q3: Does service life remain stable under 24/7 continuous climate-controlled lab operation?
A: Industrial-grade varistor components deliver consistent long-term surge protection under steady temperature and humidity laboratory conditions.
