FAQs
The device is designed for 240 Delta (3W+G) configurations and fits standard protection panel layouts. Plan for wiring to phase and ground terminals, ensure enclosure mounting in a compliant location, and integrate the internal circuit breaker with existing safe shutdown schemes. Confirm clearance for service access and follow manufacturer torque specs to avoid overheating.
A 400 kA per phase rating provides high-energy absorption capacity to handle severe utility fluctuations, lightning strikes, and motor-start transients. This reduces insulation stress, minimizes insulation failures, and improves equipment uptime even under aggressive conditions typical of manufacturing floors and outdoor installations.
Yes. Its 240 Delta (3W+G) configuration and NEMA 4 enclosure with an internal circuit breaker make it well-suited for motor control centers, switchgear, and critical data lines where reliable transient protection and easy maintenance are required.
Key certifications include UL 1449, UL 1283, and CSA standards, along with RoHS compliance. These indicate protection against electrical surges, safe operation in industrial environments, and regulatory adherence for environmental and consumer safety requirements.
By reducing surge-induced outages and extending the life of downstream equipment, the SPM400240D3R lowers maintenance and replacement costs. Features like the built-in surge counter facilitate proactive maintenance and compliance reporting, supporting a favorable total cost of ownership over the asset lifecycle.
