Stop $100K/hr Production Downtime with a $50 DIN-Rail SPD
A single surge event on an unprotected control panel doesn't just destroy a $5,000 PLC — it halts the entire factory floor. Relying solely on AC breakers leaves your sensor networks dangerously exposed. TrilPeak’s IEC 61643-11 certified DIN-rail SPDs secure both power feeds and critical signal lines instantly.
Real-world failure scenarios that threaten industrial automation uptime.
PLC & MCC Destruction
A transient voltage spike on the main AC power feed can instantly fry sensitive programmable logic controllers (PLCs) and motor control centers (MCCs). The hardware replacement costs thousands, but the unplanned line stoppage costs exponentially more.
Unprotected Sensor Networks
Most panel builders protect the AC supply but ignore the data lines. Lightning-induced surges travel up unprotected RS485 and RS232 cables from field sensors and actuators, bypassing the power SPD and burning out the control board from the data side.
Failed Project Specifications
Delivering an industrial control panel without IEC 61643-11 certified surge protection risks failing strict EPC and factory acceptance tests. Non-compliant, generic components lead to rejected panels and damaged OEM reputations.
The Complete DIN-Rail Panel Protection System
True industrial automation immunity requires a dual-threat approach. Protecting the AC power feed while leaving the RS485 signal lines exposed is a guaranteed path to PLC failure.
AC Power Feed — Main panel incoming supply
Control Signal Lines — RS485/RS232 to field devices
Site Protection — Factory structure & roof
Security Add-on — Factory surveillance lines

Why is protecting the RS485 signal lines just as important as the AC power feed?
Lightning-induced surges can enter the control panel through field wiring (sensors, actuators). If only the AC power is protected, the surge will bypass the main SPD and destroy the PLC via its communication ports. Both pathways require dedicated protection.
Do your industrial SPDs mount on standard control panel rails?
Yes, all our industrial automation AC and signal SPDs are designed for standard 35mm DIN-rail mounting, ensuring seamless integration for OEM panel builders and system integrators.
Are your SPDs certified for European and international industrial projects?
Absolutely. TrilPeak AC SPDs are CE certified and strictly comply with the IEC 61643-11 standard, making them fully compliant for integration into export-bound control panels and EPC projects.
What happens when the surge protector reaches the end of its lifespan?
Our DIN-rail SPDs feature a visual status indicator (green/red) and an optional remote signalling contact. The pluggable module design allows maintenance teams to hot-swap the cartridge without disconnecting the main power or halting the production line.
Can you supply SPDs for varying industrial control voltages?
Yes, we manufacture a comprehensive range of SPDs covering standard 120V/230V/400V AC power feeds, as well as low-voltage 12V/24V DC control lines and 5V RS485 communication loops.
