SPD100220Y3H delivers reliable panel protection through a structured Feature → Business Impact → Application approach. A 100 kA per phase interrupt rating translates to enhanced fault tolerance for critical loads, reducing the risk of equipment damage during high-energy transients and enabling longer asset life in automation lines. The EMI/RFI filtering provides up to 50 dB attenuation from 10 kHz to 100 MHz, improving signal integrity in motor drives and control loops, which directly supports tighter process control and fewer nuisance alarms. The audible alarm with silence button and a Form C relay contact enable immediate fault signaling and external integration with building management or PLC-based alerting, cutting maintenance response times. The standard surge counter offers visibility for preventive maintenance, while the left-terminal, internal mounting design simplifies installation in PRL-C panel configurations. Compatibility with 127/220 V Wye systems and 50/60 Hz operation supports a wide range of industrial applications, from packaging lines to machine cells, ensuring consistent surge protection without compromising space or wiring ease. The unit’s compliance with IBC 2006, CBC2007, and UBC Zone 4 adds a regulatory-backed layer of safety, while the 150 L-N, L-G, N-G voltages and 300 L-L MCOV provide robust operating margins under varying load conditions. This combination yields measurable benefits in uptime, energy reliability, and lifecycle cost reduction for mission-critical facilities.

FAQs
SPD100220Y3H is designed for panelboards including Eaton PRL-C, featuring left-terminal connections and internal mounting for straightforward wiring. It supports 4W+G configurations and a 127/220 V Wye rating, enabling quick drop-in protection without major rewiring. This compatibility reduces field wiring errors, shortens installation time, and minimizes panel space impact in busy switchgear rooms.
Key ratings include a 100 kA per phase interrupt rating, 200 kAIC short-circuit rating, and a 20 kA nominal discharge current. It operates at 50/60 Hz with a 127/220 V Wye rating and 300 L-L MCOV, ensuring robust protection for multi-wire panel circuits while maintaining reliable operation across a wide temperature range (-40 to 50 °C).
SPD100220Y3H carries UL 1449, UL 1283, and UL Listed certifications, signaling compliance with established safety and performance benchmarks for surge protection devices. These certifications help meet regulatory requirements for electrical installations and provide assurance of reliability in critical facilities such as manufacturing lines and data-driven control rooms.
The built-in surge counter provides ongoing visibility into transient events, enabling trend analysis and proactive maintenance planning. The audible alarm offers immediate fault notification, while the silence button reduces nuisance interruptions in quiet areas. Together with a Form C relay contact, these features streamline signaling to PLCs or BMS, reducing troubleshooting time and downtime.
Plan for left-terminal wiring and internal mounting to fit standard PRL-C panel footprints. Ensure proper clearance for heat dissipation in the panel, verify voltage compatibility (127/220 V) and frequency (50/60 Hz), and confirm MCOV margins (300 L-L) for your load profile. Use correct grounding practices and verify UL listing compliance to maintain warranty and safety.
