Adopting Class II SPD to combine “1+1” circuit for protecting low voltage equipment from surge damages. It is applied in TT system and produced according to IEC61643-11/GB18802.11 standard. Our SPD features:
Green light indicates normal and red light indicates fault for operation;
Built-in circuit breaker and thermal disconnection device, which will cut off the SPD from the power line when a fault occurs;
Impulse counter function to record lightning events;
External wiring terminal, easy for wiring and suitable for indoor applications.

8. Frequently Asked Questions
What are the necessary working conditions for the SPD?
The SPD is designed for ambient air temperatures from -40°C to +85°C (monthly mean ≤ +35°C), altitudes up to 2000m, and relative humidity ≤ 95% at 25°C. It falls under pollution level 2, use category AC-22A, and should be installed vertically within 5 degrees of inclination on a standard 35mm DIN Rail.
What type of Quality Assurance and Warranty services are provided?
We offer a Guarantee for Replacement for manufacturer-related issues within the warranty period (assuming the exterior casing is undamaged). Users can request maintenance and warranty services from local after-sales service centers or through authorized dealers.
What matters require attention during installation of the SPD?
It is crucial to determine the correct discharge current path, mark the wires to prevent additional voltage drops at the terminal, mark the PE conductor of each device to avoid unnecessary induction loops, establish an equipotential connection between the system and the SPD, and coordinate multistage PSD energy.
Why should we choose your surge protective devices?
We have over 5 years of specialized experience in manufacturing surge protective devices, exporting to over 50 countries. We carry out 100% QC inspections before shipment, keep developing the latest technology, guarantee support response within 24 hours, and can provide customized production to meet your specific requests.
How does the failure indication system work?
The built-in failure detection indicator displays green for normal operation. If the indicator turns red, it means the module has deteriorated or is invalid and needs to be replaced.
What is the reaction speed and protection level of the device?
The device operates with a high reaction speed of 10-9 seconds. It features a flame-retardant housing rated UL94 V-0, a protection rating of IP20, and complies with IEC61643-11 and GB/T18802.11 standards.
