Siemens TPS-F11 80 FM Surge Protection Device

Siemens Sentron TPS-F11 80 FM Surge Protection Device is a DIN‑rail mounted surge protector within the Siemens Sentron TPS family, engineered to shield electrical circuits from transient overvoltage events in industrial environments. The TPS line emphasizes modular, replaceable protection modules and remote contacts to simplify installation and enable fast restoration after a surge. As part of Siemens’ Industrial Surge Protection Devices portfolio, it provides protection for power and signal paths in control panels, with typical applications including drives, PLCs and instrumentation in manufacturing and process‑control systems. The ISPD ecosystem supports modular configurations and easy retrofits or new builds, with coverage for a range of low‑voltage power needs and UL‑listed signal‑protection variants. The TPS‑F11 80 FM variant embodies this architecture in a compact form factor designed for Siemens’ protection strategy, intercepting transients at the circuit entry to help extend downstream equipment life and reduce downtime in machine automation and control cabinets.
