Description

SLV-10S/SLV-20S is a compact ultra-low residual voltage surge protection device designed for single-phase power supply systems, ideal for fine lightning protection in LPZ 1-2 and subsequent lightning protection zones. As a series-installed fine arrester at the front end of equipment, it integrates full-mode protection to shield against surges in line-neutral, line-earth, and neutral-earth paths.

Equipped with LED status indication (green: normal; red: failed) and open-circuit failure mode, it provides clear operational status and safe fault handling. The compact size (97mmx69mmx55mm) and 35mm DIN Rail mounting make it suitable for space-constrained environments. It supports parallel connection for loads exceeding 15A without changing residual voltage, making it versatile for homes, offices, and light industrial equipment protection.

Applications
● Single-phase power systems in residential buildings, offices, and small commercial spaces
● Front-end protection for household appliances, office equipment, and sensitive electronics
● Light industrial single-phase equipment and control systems
● Indoor power supply lines in apartments, shops, and small workshops
● Auxiliary equipment protection in communication rooms and data centers

Notices

1.For loads exceeding 15A, parallel installation of multiple SPDs is allowed to maintain protection performance.

2.Use wiring with cross-sectional area 2.5mm²-10mm² and tighten screws to 3N·m torque.

3.Ensure reliable grounding with ground resistance ≤4Ω to guarantee surge diversion efficiency.

4.Replace the SPD immediately if the LED indicator turns red (failure status) or after severe surge impact.

5.Do not disassemble the product; improper operation may damage internal components.

6.Avoid using in environments beyond the specified temperature and humidity range.

FAQ

Q1: Can SLV-10S/SLV-20S be used for air conditioners or refrigerators?

A1: Yes, it is suitable for protecting household appliances with rated current ≤15A; for larger loads, parallel installation is recommended.

Q2: What is the difference between SLV-10S and SLV-20S?

A2: The core difference is discharge current: SLV-10S has In=10kA/Imax=25kA, while SLV-20S has In=20kA/Imax=40kA. Other parameters and design are consistent.

Q3: Does the product support hot-swapping?

A3: No, hot-swapping is not supported. Please disconnect the power supply before replacing the SPD.

Q4: What is the failure mode of this SPD?

A4: It adopts open-circuit failure mode, which automatically disconnects from the circuit when faulty to avoid short circuits or other hazards.

Q5: Can it be installed outdoors?

A5: No, it is designed for indoor use only. For outdoor applications, choose products with IP67 protection level.
