SPD100208Y3B delivers a clear pattern of value: Feature → Business Impact → Application. The device provides 100 kA per phase protection with a 200 kAIC short-circuit rating, delivering high-energy surge handling that minimizes the risk of transformer and relay damage in critical feeders. This translates to improved equipment uptime and lower unplanned maintenance costs in manufacturing lines, data centers, and process plants. The EMI/RFI filtering capability (up to 50 dB from 10 kHz to 100 MHz) reduces electro-magnetic interference, enhancing signal integrity for control circuits and communications within switchgear enclosures. The integrated 4W+G configuration and internal mounting simplify installation, enabling faster commissioning and safer, neater panel assemblies for OEMs and end users. With a Form C relay, audible alarm with silence button, and a surge counter, engineers gain immediate visibility and warning control, reducing mean time to detect and respond to surges. The unit’s 120/208 V, 50/60 Hz compatibility supports broad industrial applications, including modernization projects and retrofit programs that require reliable protection without expanding footprint. The MCOV of 300 V and operating temperature range of -40 to 50 °C ensure dependable operation in harsh environments, while the 9.5 in × 5.4 in × 3.45 in form factor and 3.5 lb weight offer a compact footprint suitable for crowded switchgear spaces. Industry professionals appreciate the 15-year warranty and UL 1449 listing as a longstanding assurance of performance and reliability, which supports lifecycle cost reductions and long-term ROI for critical electrical infrastructure. In practice, the SPD100208Y3B is a robust choice for engineers aiming to unify protection, monitoring, and compliance in a single protective device, especially when remote display compatibility with existing gear is a priority.
