100 kA per phase surge capability provides decisive protection for critical loads, reducing the frequency and severity of transient events that would otherwise disrupt production. The device's 200 kAIC short-circuit rating adds a wide margin for fault conditions, while the 400Y/230V (4W+G) configuration ensures compatibility with typical industrial power systems. By covering L-N, L-G, N-G, and L-L paths, SPD100400Y2F safeguards panelboards and downstream equipment in manufacturing, data centers, and process lines. EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, improving controller, drive, and sensor signal integrity. Reduced electrical noise translates to fewer nuisance trips and more stable operation of PLCs and protection relays. The protection is particularly valuable in environments with high switching activity, variable loads, and frequent motor starts, where clean power supports higher efficiency and longer equipment life. The internal integrated mounting and top-terminal design simplify installation, speeding commissioning and reducing cabinet wiring complexity. With a 12x12x6-inch footprint, it fits standard enclosures and supports space-efficient protection schemes in panelboards (PRL-C). The 50/60 Hz compatibility and wide operating temperature (-40 to 50 °C) make it suitable for manufacturing floors, data centers, and utility rooms across diverse geographic regions. Audible alarm with silence button, surge counter with rest button, and Form C relay signaling enable proactive maintenance and quick fault diagnosis, while the EMI/RFI filtering adds layered protection beyond a simple surge device for regulatory compliance and improved reliability.
