The Fotek SSR-10 10A solid state relay is an electronic device that works as a contactless switch, designed to control high-current electrical loads using a small control signal. It is widely used in applications such as temperature control in electric heating systems, offering fast and reliable switching.
Main features:
- Input voltage: 3-32 VDC
- Input current: DC 3-10 mA
- Output voltage: 24-380 VCA
- Rated output current: 10A (with 3/2 safety margin to avoid overloads)
- Voltage drop in active state: 1.5V
- Leakage current in off state: 2 mA
- On and off time: 10 ms
- Withstand voltage: 1000 VAC
- Insulation resistance: 1000 MΩ / 500 VDC
- Operating ambient temperature: -30 to 75 °C
- Installation method: screw-mounted
- Working indicator: LED
Advantages of the Fotek SSR-10 10A solid state relay:
- Long service life thanks to the absence of mechanical contact.
- No sparks or noise during switching.
- No electromagnetic interference, ensuring stable operation.
- High switching speed and strong anti-interference capability.
- Compact design, resistant to vibration, corrosion and explosion prevention.
- Compatible with TTL, DTL, HTL integrated circuits, among others.
Typical uses: This relay is ideal for controlling resistive electrical appliances, such as heating cables and electric heating pipes. It is recommended to leave a 3/2 current margin compared with the rated current to avoid damage and ensure proper heat dissipation, especially when the load exceeds 5A. For high loads, the use of a special heat sink for solid state devices is recommended.
Precautions and recommendations:
- Do not use for inductive loads or motors, as it is designed for resistive loads.
- Pay attention to heat dissipation to avoid overheating.
- Install correctly using screws to ensure good thermal and electrical contact.
This Fotek SSR-10 10A solid state relay is an efficient and reliable solution for industrial and domestic applications that require precise control of electrical loads with high durability and safety.

Customer Questions & Answers
What are the key advantages of the Foteh SSR-10 10A solid state relay compared with a traditional electromechanical relay?
The SSR-10 10A offers contactless switching, which means zero mechanical wear, no noise, and greater resistance to vibration and corrosion. It also produces no sparks or electromagnetic interference and allows faster switching. The main trade-off is that it only has one contact group and can heat up at high currents, so thermal management must be considered.
What maximum temperature can it reach during operation, and how should thermal dissipation be managed?
The SSR can heat up significantly under loads close to 10 A. When operating above 5 A, it is essential to fit a suitable heatsink to prevent overheating. The heatsink temperature should not exceed 75-80 °C during continuous operation. Do not install it in enclosed spaces without airflow.
What common problems can occur with this SSR, and how can they be prevented or solved?
The most common faults include overheating due to poor thermal dissipation, use with non-resistive loads, or overloading the current rating. To avoid damage, always use a heatsink suitable for the load, do not exceed 70% of the maximum current, and check load compatibility. If the SSR remains permanently on, check for overloads or voltage spikes.
What is the Fotek SSR-10 10A solid state relay used for?
It is used to control resistive electrical loads, especially in electric heating systems and temperature control, using a small control signal.
How is the Fotek SSR-10 10A solid state relay installed?
It is installed using screws, ensuring good thermal and electrical contact. It is important to use a heat sink if the current exceeds 5A.
What precautions should I take when using this relay?
It should only be used with resistive loads, a 3/2 current margin should be left compared with the rated value, and proper heat dissipation must be ensured to avoid overheating.
Is it compatible with TTL circuits?
Yes, it is compatible with TTL, DTL, HTL integrated circuits and similar types.
What is the maximum current this relay can handle?
It supports up to 10 amperes with a safety margin to prevent damage from overload.
