FAQs
The SPC050240D7P is designed for external-side mounting on 240V Delta power feeds. It integrates with standard control panels and enclosures, enabling straightforward retrofit in existing machinery or new builds. For best results, ensure the panel has space for the device footprint and that the mounting surface is clean and structurally sound. The unit’s NEMA 4X enclosure tolerates washdown areas and adverse environments, reducing field maintenance needs.
This model provides a 50 kA surge rating, delivering robust transient suppression for sensitive control electronics and drives. It combines filtering with a Form C relay to offer both electrical noise reduction and status signaling. These features help protect PLC inputs, motor drives, and other automation assets from damaging spikes and EMI, supporting reliable operation and longer equipment life.
Yes. The device is housed in a NEMA 4X enclosure, which is designed for moisture, dust, and washdown exposure. This makes it well-suited for outdoor installations, damp plant areas, and harsh industrial environments where protection against ingress and corrosion is critical. Proper mounting and clearance should still be observed per installation guidelines.
The SPC050240D7P carries UL 1449 certification, signaling compliance with essential surge protection standards. The NEMA 4X enclosure rating further demonstrates suitability for demanding environments. Together, these certifications support regulatory compliance, system reliability, and end-user confidence in protection performance for critical loads.
By significantly reducing unplanned outages and equipment damage, the SPC050240D7P lowers downtime costs and extends the life of downstream devices like PLCs and drives. Maintenance is typically minimal beyond periodic inspection of the enclosure and verification of the relay status. The 10-year warranty also helps secure long-term ownership cost reductions and budgeting predictability.
