SPD100400Y2D delivers a 100 kA per phase surge current rating, aligning with demanding industrial transients. This robust capability reduces the risk of damage to transformers, drives, and PLCs during lightning events or switching surges, translating to lower downtime and longer equipment life. Designed for 400Y/230V three‑phase systems, it fits panelboards in manufacturing lines, data centers, and packaging equipment. Feature: Multi-path protection across L-N, L-G, N-G, and L-L ensures every conductor path is safeguarded. Business impact: covers complete phase-to-neutral/ground protection, lowering chances of partial damage and failed components. Application: ideal for panelboards and switchgear with mixed conductor layouts in industrial automation. EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, suppressing noise on control signals. Business impact: cleaner signals improve drive performance, PLC reliability, and measurement accuracy. Application: robotics cells, CNC machines, and process lines where precise control is essential. Audible alarm with a silence button and a Form C relay contact provides immediate fault signaling and remote integration. Business impact: enables proactive maintenance and easier integration with building or machine monitoring systems. Application: quick response in maintenance dashboards and centralized protection schemes. Bottom-terminal design and internal integrated mounting simplify installation, cabling, and service access. Business impact: reduces field wiring time, enables faster retrofits, and minimizes installation errors. Application: OEM builds, retrofit projects, and new installs in panelboard assemblies. UL 1449, UL 1283, and UL Listed certifications, plus warranty replacement support, strengthen compliance and lifecycle value. Business impact: ensures regulator-ready protection and predictable replacement costs, protecting total cost of ownership. Application: facilities and OEMs requiring standards-based protection and long-term vendor support.
