The 481-00252-32 is a TS4-A-F (Fire Safety) module-level rapid shutdown device . Designed to bring NEC-compliant rapid shutdown to standard PV modules, the TS4-A-F enhances system safety and reliability while supporting modern high-current and bifacial modules. It communicates shutdown signals over existing PV conductors using PLC, enabling fast, code-compliant shutdown without additional wiring.
NEC 2017 / 2020 / 2023 Rapid Shutdown Compliant
Meets NEC 690.12 when used with a Tigo RSS Transmitter or an inverter with a certified built-in Tigo transmitter.
High Input Current Rating
Rated for 20A IMP / 25A ISC to accommodate high-current and bifacial PV modules.
Automatic Module-Level Shutdown
PV modules enter rapid shutdown mode automatically upon AC grid loss.
PLC Communications
Power-line communications transmit shutdown signals directly over PV conductors.
Fast, Simple Installation
Snaps onto standard module frames or mounts directly to racking.
Residential & Commercial Solar Arrays
Adds rapid shutdown compliance to new or existing PV systems.
Fire-Safety Upgrades
