Information About FS140
The FS140 is part of the Siemens FirstSurge family of residential surge protective devices designed to protect entire electrical systems from damaging transient overvoltages. It is installed at the main electrical load center where it intercepts incoming surge energy before it reaches branch circuits and connected equipment. The device continuously monitors its internal protection status using integrated LED indicators and an audible alarm that alerts users if the surge protection components require service or replacement. Designed for residential installations, the FS140 provides commercial-grade surge protection while maintaining a compact, wired configuration that integrates easily into existing electrical distribution systems.
Key Features:
- 140,000 Amp Surge Capacity: Provides high-energy surge protection for complete residential electrical systems.
- Whole-House Protection: Installed at the load center to protect connected appliances and electronic equipment.
- Fast Response Time: Responds to transient surges in approximately one nanosecond.
- Visual Status Monitoring: Green LEDs indicate proper protection while a red service LED signals replacement requirements.
- Audible Alarm: Produces an audible warning if the protection system has been compromised.
- Single-Phase Design: Designed for 120-volt residential electrical installations.
- Wide Operating Temperature Range: Operates reliably from -40 °C to +60 °C.
- Commercial-Class Construction: Built to deliver long-term surge protection for residential power distribution.
The FS140 delivers the reliability and precision required for whole-house surge protection and long-term electrical system safety.
