FAQs
External side mounting is designed to simplify placement on available panel surfaces and allow straightforward wiring access while preserving enclosure integrity. Ensure adequate clearance for the audible alarm and wiring, and verify the mounting surface supports the device weight of about 4 lb. Plan for proper heat dissipation and align with the SPC series installation guidelines.
The SPC150240H3P is engineered for 240V delta (4W+G) configurations, delivering 150 kAIC interrupt rating to absorb transient surges. This reduces voltage spikes that can threaten motor drives and PLCs, improving reliability in automated lines and process equipment while meeting UL 1449 protection standards.
The audible alarm provides immediate fault indication, enabling rapid notification to maintenance teams and faster fault diagnosis. This feature helps reduce mean time to repair, minimize unplanned downtime, and support proactive protection strategies in high-demand manufacturing environments.
Yes. The device carries UL 1449 certification and uses a NEMA 4X enclosure, designed for wet, dusty, and outdoor environments. This combination supports compliance, longevity, and safer operation in challenging settings such as washdown areas and outdoor control panels.
By reducing transient damage to motors, drives, and controllers, the SPC150240H3P lowers repair and replacement costs and minimizes downtime. Coupled with a 10-year warranty and SPC series compatibility, this translates to longer equipment life, improved uptime, and predictable lifecycle budgeting for automation investments.
