The following thermal derating curves illustrate the maximum load current that our SSRs can manage under varying ambient temperatures and heatsink sizes. It is crucial to select a heatsink that is most suitable for your specific application. ## **10A VERSIONS:** **25A VERSIONS:** **==> picture [69 x 39] intentionally omitted <==** **----- Start of picture text -----**

## **Considerations - Switching Type** In applications requiring precise temperature management, solid-state relays (SSRs) play a crucial role. Specifically, the Zero Cross Switching type of SSR is commonly employed to regulate heaters based on signals from a temperature controller. This technology proves particularly valuable in scenarios where high-frequency switching occurs—such as when a heater cycles on and off frequently over short intervals for extended periods. **Littelfuse.com** ©2024 Littelfuse, Inc.

Revised: 07/18/2024 **3 of 7** **Solid State Relays** SRP1–CB...F **==> picture [56 x 55] intentionally omitted <==** **==> picture [314 x 55] intentionally omitted <==** ## **Considerations - Inrush Current** It’s essential to recognize that variations exist between different types of heating elements, especially in hot or cold conditions. While it is generally expected that heating elements exhibit no inrush current, in certain heating elements cold conditions can lead to an inrush current equivalent to 1.4 times the nominal current. To mitigate this, we highly recommend oversizing the current rating and ensuring an appropriately sized heatsink. Doing so improves the relay’s thermal endurance and extends its operational lifespan. So, when selecting an SSR, consider using one with a capacity approximately 1.4 times that of the heater or operating the SSR at only 75%-80% of its maximum capacity. The following table provides guidance for choosing the right SSR for a specific heater load. **==> picture [494 x 62] intentionally omitted <==** **----- Start of picture text -----**

*The SRP1 series is engineered for durability, having undergone rigorous testing to ensure a minimum lifespan of 100,000 Endurance cycles, with each cycle consisting of a 1-second activation followed by a 9-second rest, at twice the rated current. This means that the relay can be expected to operate reliably for 100,000 times under these conditions, but it may have a shorter or longer lifetime depending on other factors, such as switching frequency, environmental temperature, and humidity. **==> picture [493 x 191] intentionally omitted <==** **----- Start of picture text -----**

Revised: 07/18/2024 **5 of 7** **Solid State Relays** SRP1–CB...F ## **Short-Circuit Protection by Fuse** To safeguard solid-state relays (SSRs) against load short circuits, the use of fuses is essential, especially fast-acting ones. Here are the key considerations: - Fuse Selection: The I²t value (energy withstand capability) of the fuse should be less than half of the I²t value of the relay. Standard fuses are inadequate because they cannot react swiftly enough to prevent fault currents from exceeding the maximum levels that thyristors (used in SSRs) can handle. Therefore, we strongly recommend employing ultra-fast fuses. - Fuse Placement: Position the fuse in front of the SSR in the circuit. This strategic placement ensures that if the relay must unexpectedly break the earth insulation (due to overheating, case damage, or leakage with the heatsink), the fuse will protect the entire circuit from firing. - Resource for Fuse Options: For the most suitable fuse options, consider checking the **Littelfuse** - No. E183688 **website.** ## **Standards Conformity & Certifications** ## Product Safety Certifications Products tested, compliant and certified to the following standards that states the requirements for electrical products to ensure they are safe for consumers to use. |CERTIFICATION
