Product Overview
The Tigo TS4-A-2F is a module-level rapid shutdown device that serves two PV modules, part of Tigo's Fire Safety line. This listing has 2.2 m MC4 output cables. The TS4-A-2F complies with NEC 2017, 2020, and 2023 690.12 Rapid Shutdown specifications when installed with the Tigo RSS Transmitter or an inverter with a built-in Tigo certified transmitter (Tigo TS4-A-2F Datasheet 002-00092-00 Rev 2.9).
Tigo makes TS4-A-2F versions with different current and power ratings. The rows below are the ones those versions share; check the part number on the unit for its current and power ratings.
Best For
- Module-level rapid shutdown, two modules per unit: With a Tigo RSS Transmitter or an inverter with a built-in Tigo certified transmitter.
- Layouts that need 2.2 m output leads: Tigo lists 2.2 m and 2.4 m output options.

What You May Also Need
Usually required
- A Tigo RSS Transmitter or an inverter with a built-in Tigo certified transmitter: See the Tigo 492-00000-51 outdoor transmitter kit.
- One unit per two modules.
May be required
- Rapid shutdown labels: For example PV Labels 05-523 (2023 NEC).
- Other rapid shutdown parts: See rapid shutdown.
Optional upgrades
- One module per unit: See the TS4-A-F.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Check the ratings on your unit. Maximum output current (15 A or 20 A class) and maximum power differ between TS4-A-2F part numbers in Tigo's datasheet.
- Inverter list. For inverters with a built-in Tigo certified transmitter, check the Tigo UL PVRSS certified inverter list (tigoenergy.com/ul-pvrss), viewed Oct 8, 2026; no revision number.
- Wait 30 seconds. Tigo's RSS IOM says to wait 30 seconds after rapid shutdown activation before disconnecting DC cables.
- Inverter pairing. Do not assume a specific string inverter, hybrid inverter or microinverter model is listed. Check the maker's current certified list and the document revision or view date before design.
