Feature the SPD100240S3D provides high-energy surge protection with 100 kA per phase and a 200 kAIC short-circuit rating, designed for 120/240 V split-phase systems. Business impact includes protecting critical drives, controllers, and PLCs from damaging transients, reducing downtime and replacement costs in demanding environments. This enables reliable operation in panelboards (PRL-C) with a compact footprint and straightforward wiring, accelerating project timelines and improving overall equipment availability. Application spans industrial automation, manufacturing lines, and process controls where transient events threaten uptime and product quality. The EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, improving signal integrity and reducing misreads in sensitive control circuits, which translates to fewer false trips and smoother operation. In practice, this supports cleaner PLC inputs, motor drive stability, and better communication on fieldbuses without costly rerouting. Audible alarm with silence button and a surge counter with rest button provide immediate, actionable insights, enabling rapid fault analysis and proactive maintenance planning. Form C relay contact offers straightforward integration with building management systems or control logic, allowing proactive alerts and shutdown sequencing when surges occur. The device mounts with internal integration and bottom terminals, simplifying installation in tight panels and minimizing labor while maintaining code-compliant protection. Meets or exceeds IBC 2006, CBC 2007, and UBC Zone 4 requirements, which helps electricians and engineers streamline code compliance during audits. With standard feature package including the surge counter and compact form, it’s a practical upgrade for new builds or retrofits, delivering measurable reliability improvements and a clear path to ROI for protection-first electrical strategies.
