Internal integrated mounting and right-terminal wiring simplify installation by minimizing field wiring runs and ensuring solid, corrosion-resistant connections. The compact, all-in-one design reduces enclosure clutter and eases retrofits into crowded electrical rooms. Technicians benefit from faster commissioning, fewer errors, and a cleaner signal path when protecting panelboards against transient voltages. Withstanding 100 kA per phase surge current and a 200 kAIC short-circuit rating, the SPD100240D3G provides robust protection for 240 V delta networks and panelboards (PRL-C). This capability minimizes equipment damage during lightning events or switching surges, preserving critical drives and controllers. The device supports 50/60 Hz operation and maintains 320 L-G and 320 L-L MCOV, ensuring reliable performance across a broad range of industrial mains. EMI/RFI filtering delivers up to 50 dB of noise attenuation from 10 kHz to 100 MHz, reducing conducted and radiated interference that can affect PLCs, drives, and sensors. The result is steadier control loops, fewer nuisance trips, and improved accuracy in measurement systems. In practice, this translates to higher uptime and more predictable process behavior in electrically noisy environments. Audible alarm with silence button and a surge counter with rest button provide clear, auditable protection status without interrupting operation. The Form C relay contact enables straightforward remote signaling and integration with building management systems or automation controllers. These features support proactive maintenance, faster fault detection, and documented event histories for compliance reporting. Standard feature package includes surge counter and warranty-friendly right-terminal design, simplifying procurement and field service. Compatible with panelboards (PRL-C) and the Eaton protection ecosystem, this SPD aligns with UL standards and industry best practices, delivering predictable protection, reduced lifecycle costs, and straightforward procurement for engineering teams.
