FAQs
SPD100240D2N is designed for external sidemount installation onto distribution equipment. Mounting hardware aligns with standard panel or switchgear surfaces, while input and output conductors connect to designated terminals for phase and ground. Follow the installation manual to ensure proper torque, clearance, and enclosure integrity, minimizing wiring complexity and enabling straightforward future extensions.
The device provides a 100 kAIC interrupt rating and operates at 240V delta (3W+G), delivering high-energy surge clamping for three-phase systems with a grounded delta configuration. This reduces the likelihood of coil or drive damage in motors, drives, and contactor circuits, preserving uptime and protecting sensitive electronics during utility transients.
Yes. The SPD100240D2N uses a NEMA 4X enclosure, designed to resist dust, water ingress, and corrosion, making it suitable for indoor, damp, or outdoor installations. This enclosure rating, combined with robust construction, supports reliable protection in factory floors, outdoor equipment pads, and process facilities where environmental exposure is a concern.
SPD100240D2N holds UL 1449 certification, which validates safety performance for surge protection devices. This certification helps meet electrical safety requirements in most regional codes and standards, simplifying audits, qualification processes, and insurance reviews while supporting a compliant, auditable protection scheme for critical electrical infrastructure.
Total cost of ownership is favorable thanks to a 15-year warranty and a standard feature package that reduces procurement delays. Maintenance considerations are minimal—reliability is enhanced by UL 1449 safety certification and a rugged enclosure. Routine inspections and periodic verifications per the installation manual help ensure continued protection without unexpected downtime.
