In10kA 2pole Class III AC Surge protector In10kA 2pole

FV10D/2-275S

FATECH FV10D/2-275S is a 2-pole AC surge protective device designed for low-voltage single-phase power distribution systems. It effectively suppresses lightning surges, transient overvoltages and switching surges to protect household appliances, office equipment, small electrical loads and distribution boxes from damage.

This SPD features compact structure, stable performance and standard DIN-rail installation for easy wiring and maintenance. With reliable protection performance and long service life, it is widely used in residential buildings, shops, small industrial sites and light commercial applications to ensure safe and stable operation of electrical circuits and equipment.

-Consisting of a base part and MOV pluggable protection modules.

-For using in the lightning protection zones concept at boundary 1-2.

-The core parts are metal oxide vristor components with high discharge capacity.

-Low residual voltage and quick response.

-Reliable control thanks to Thermo Dynamic Control disconnector.

-With remote signaling contact for control device.

-Fault indication via red mark in the inspection window.

-Protection mode: L-PE,N-PE.

What does remote signaling do on FATECH SPD?

The remote signaling contact monitors the working status of the SPD. It sends an alarm signal when the SPD fails or needs replacement, enabling real-time monitoring and maintenance.

Why choose FATECH surge protection devices?

FATECH SPDs feature TUV & CE certification, stable performance, long service life, and professional technical support. They are widely used in PV, industrial, lighting, network, and residential applications with high cost-performance.

Do you provide OEM / ODM for surge protection devices?

Yes, we support OEM and ODM services

What applications are SPDs widely used in?

SPDs are widely used in residential buildings, commercial centers, industrial factories, solar PV power stations, LED lighting, security CCTV, telecom base stations, data centers, and infrastructure projects.

Why is good grounding important for SPD performance?

Effective grounding provides a low-resistance path for surge current to discharge quickly. Poor grounding will reduce protection performance, increase residual voltage, and may cause equipment damage.
