FAQs
The SPD100400Y2B-ND features an internal integrated mounting and a standard feature package that eliminates the need for external display interfaces. Install by mounting within compatible switchgear, busways, or panelboards, connect line, load, and ground per the 400Y/230V (4W+G) configuration, and verify proper wiring with the device’s integrated indicators. This simplifies retrofit projects and minimizes field wiring complexity while ensuring reliable protection from the moment of power restoration.
The 200 kAIC interrupt rating indicates the device can interrupt high-energy fault currents without failure, while 100 kA per phase surge current shows the SPD can clamp transient surges per phase effectively. Together, they protect critical loads in switchgear and panelboards from lightning and switching transients, reducing the likelihood of component damage and unplanned downtime in demanding industrial environments.
Yes. The device is rated for 400Y/230V with a 4W+G configuration and supports 50/60 Hz operation. This makes it compatible with common three‑phase four‑wire electrical systems found in manufacturing facilities, data centers, and distribution panels, ensuring effective surge suppression without voltage compatibility issues.
The SPD100400Y2B-ND carries UL 1449, UL 1283, and UL Listed certifications, confirming adherence to established electrical protection and EMI/RFI standards. While CE and IP ratings are not listed in the provided data, UL listing provides strong safety and performance validation for industrial environments, supporting compliance in many regional markets and aiding safety documentation for procurement and audits.
The device includes an audible alarm with a silence button, a Form C relay contact, and a surge counter with a rest button, enabling straightforward condition monitoring and event auditing. These features simplify maintenance planning, support rapid fault diagnosis, and help quantify protection uptime improvements, contributing to reduced downtime costs and clearer justifications for capital expenditure in protection upgrades.
