With a 100 kA per phase surge rating, the SPD100400Y2B delivers robust protection that minimizes downstream equipment damage and reduces unplanned downtime on critical automation lines. This translates to higher overall equipment effectiveness (OEE) and lower maintenance costs for panel assemblies in manufacturing and process environments. EMI/RFI filtering up to 50 dB lowers electrical noise that can affect PLCs and drives, boosting reliability of control systems and accuracy of sensor data without costly redesigns. An audible alarm with silence button enables quick fault recognition by maintenance teams, while the Form C relay contact enables remote signaling and dashboard integration, streamlining MTTR and improving incident response. The unit’s internal integrated mounting simplifies installation in crowded panels, saving time and reducing field wiring errors. A surge counter with rest button provides traceable protection status for audits, while the 15-year warranty reinforces total cost of ownership and long-term protection strategy.

FAQs
The SPD100400Y2B uses internal integrated mounting and is designed for use with switchgear that includes a remote display. Installation is straightforward within standard 4W+G, 400Y/230V panels, minimizing panel space usage and wiring complexity while enabling remote status visibility.
This device provides 100 kA per phase surge capability and 200 kAIC interrupt rating. These ratings matter because they determine the level of transient energy the protection device can safely divert, reducing the risk of damage to downstream devices like drives, PLCs, and sensors during voltage spikes.
Yes. It is UL 1449 Listed for surge protection. It also aligns with performance expectations from established codes and standards such as IBC, CBC, and UBC Zone 4, supporting safety and reliability in industrial installations.
EMI/RFI filtering up to 50 dB helps suppress high-frequency interference that can disrupt PLCs, drives, and sensors. This leads to more stable operation, improved data integrity, and fewer nuisance faults without requiring additional filtering hardware.
The SPD100400Y2B carries a 15-year warranty, reducing long-term maintenance risk and replacement costs. Its protective features—alarm signaling, remote signaling via Form C relay, surge counting, and reliable surge handling—contribute to higher uptime and lower total cost of ownership in industrial power networks.
