Printed in "Standards compliance UL 1741 PVSRE, UL 1741 PVRSS, CSA 22.2, IEC 62109, NEC 690.12" (PVSRE as printed there; the Rapid Shutdown section prints "UL 1741-compliant PVRSE Yes"). These are the maker's statements; no listing record was checked.
Printed as "Communications PLC"; the features list describes "Power-line communications (PLC) signaling – rapid shutdown signaling over PV conductors".
Printed as "Maximum current (IMP /ISC) 20 A/25 A" in the 25 A column, which is the column of this part number (485-00252-24 is listed under "25 A ISC"). 25 A is the ISC figure; IMP is 20 A. The current is printed "per unit"; the TS4-A-2F has two inputs ("Number of inputs 2").

Printed as "Maximum current (IMP /ISC) 20 A/25 A" in the 25 A column, which is the column of this part number (485-00252-24 is listed under "25 A ISC"). 25 A is the ISC figure; IMP is 20 A. The current is printed "per unit"; the TS4-A-2F has two inputs ("Number of inputs 2").
Printed as "Maximum input voltage 80 V" (TS4-A-F) or "Maximum voltage per input 80 V" (TS4-A-2F); the same figure applies to both current columns. Voltage range (VMP) is printed as 16 to 80 V.
Printed as "Maximum output current (IMAX)" with 20 A in the 25 A column. The maximum output power (PMAX) is printed as 1400 W (700 W/input) in this column.
Printed as "Operating temperature range -40 – 85 °C (-40 – 185 °F)*" with the footnote "* 20 A UL rating: -30 – 75 °C (-22 – 167 °F)"; the footnote names the 20 A UL rating and this part is a 25 A ISC part.
Tigo prints that 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". The General section also lists NEC 690.12.
Tigo Energy's TS4-A-2F datasheet (Rev. 2.9, dated 2026-03-20). Specifications are printed in two columns, 20 A and 25 A, and the ordering table groups part numbers under 20 A ISC and 25 A ISC.
