FAQs
SPD100240D1O is designed for external side mounting on distribution equipment. When installing, ensure there is accessible service clearance, define conduit routes, and follow torque specifications for connections. The NEMA 4X enclosure provides protection in harsh environments, while UL 1449 compliance confirms safety performance for industrial settings.
The device offers a 100 kAIC interrupt rating, compatible with 240V delta (3W+G) systems. This combination minimizes transient-induced damage to motors, drives, and controllers, reducing nuisance outages and extending equipment life in manufacturing lines and process plants.
Yes. The NEMA 4X enclosure and sidemount design are intended for rugged environments, including outdoor panels and washdown areas. Ensure mounting is compliant with the installation manual and that external side mounting remains accessible for maintenance and testing.
SPD100240D1O carries UL 1449 certification for safety performance. The NEMA 4X enclosure rating supports harsh environments, including outdoor and washdown conditions. While SIL or CE certifications are not listed in the data, the device aligns with standard industrial surge protection and enclosure requirements.
By preventing transient overvoltages from damaging critical loads, the SPD reduces downtime and extends equipment life. The 15-year warranty lowers long-term maintenance costs, while external mounting speeds installation and reduces commissioning time, delivering meaningful total cost of ownership benefits for plant operations.
