CE T1+T2 275V 40ka SPD 2poles AC Surge Protector - Surge ...

A 40kA AC SPD (Surge Protective Device) is a crucial electrical component that protects homes, businesses, and industrial equipment from damaging voltage spikes (transients) caused by lightning or switching, handling up to 40,000 Amps of surge current , typically featuring MOV technology, DIN rail mounting for easy installation, status indicators (Green/Red), and compliance with standards like IEC 61643-11 for reliable, fast protection in 1, 2, 3, or 4-pole configurations.

What it does:

Diverts Surges: When a voltage spike hits, the SPD's internal Metal Oxide Varistors (MOVs) temporarily lower their resistance, diverting excess current safely to the ground and clamping the voltage to a safe level.
Protects Equipment: Prevents damage to sensitive electronics, motors, compressors, and circuit boards from sudden overvoltages.

Key Specifications & Features:

40kA (Imax): Maximum surge current capacity, indicating high-energy handling.
AC Voltage Rating: Common ratings include 275V (for 230V systems), 385V, 400V, or 600V, depending on the application.
Type 2 (or Type 1): Type 2 SPDs are common for main panel installations (like in homes/offices), while Type 1 handles even higher direct lightning energy.
Poles: Available in 1P, 2P, 3P, or 4P for single-phase or three-phase systems.
DIN Rail Mount : Modular design for easy mounting on standard 35mm DIN rails in electrical panels.
Indicators: Green (normal) or Red (fault/replace) LED lights to show status.
Fast Response: Acts within nanoseconds (e.g., ≤25ns) to stop surges quickly.

Where it's Used:

Residential distribution boards (main panels).
Commercial buildings.
Industrial facilities (factories, petrochemical, wind/solar farms).

In simple terms: It's like a high-speed electrical pressure relief valve, absorbing massive, brief energy spikes to keep your entire electrical system safe and functioning, says a YouTube video .

What should you never plug into a surge protector?

2025 Update] What You Should NEVER Plug into A Power Strip ...

You should never plug high-power appliances like space heaters, refrigerators, microwaves, and air conditioners into a surge protector or power strip because they draw too much power and can cause the strip to overheat or start a fire. These appliances should always be plugged directly into a wall outlet for safety.

High-power appliances to avoid

Heating appliances:

Space heaters, toaster ovens, and hair dryers can draw a lot of wattage and cause power strips to overheat.
Refrigerators and freezers:

These appliances cycle on and off frequently, and the compressors can overload a power strip.
Major kitchen appliances:

This includes microwaves, coffee makers, slow cookers, and blenders.
Other appliances:

Air conditioners and sump pumps should also be plugged directly into a wall outlet.

Do not "daisy chain" power strips by plugging one into another.
Never use an indoor power strip in a wet or damp area, such as a kitchen or bathroom.
Always check the wattage rating of your power strip and the appliances you are plugging in to ensure you do not overload it.

What is the surge rating of SPD?

SPDs are marked with a Nominal Discharge Current Rating that is verified to ensure that the SPD is fully operational when subjected to 15 surges at the marked level. Nominal Discharge Current Ratings include 20 kA, 10 kA, 5 kA and 3 kA , and depends on the “Type” of SPD.
