FAQs
Install the SPM120240D3T in a suitable main or distribution panel with a 240 Delta (3W+G) configuration. The unit features an NEMA 4 enclosure and an internal terminal breaker to simplify wiring and reduce external components. Follow manufacturer torque specs, maintain proper clearances, and ensure the surge protective device is correctly grounded for optimal protection.
A 120 kA per phase rating dissipates large transient currents from faults or switching events, protecting sensitive drives, controllers, and motors. This capacity minimizes insulation stress and potential downtime, enabling more reliable start-ups and steady operation in demanding industrial environments.
The SPM120240D3T carries UL 1449 and UL 1283 listings, CSA certification, and RoHS compliance. These certifications verify safety, electromagnetic compatibility, and environmental standards, helping you meet regulatory requirements and maintain supplier qualification lists.
Yes. RoHS compliance ensures restricted use of hazardous substances, aligning with modern environmental standards. The 240 Delta (3W+G) wiring, NEMA 4 enclosure, and internal terminal breaker are designed for standard industrial panels, enabling straightforward retrofits and scalable protection across manufacturing lines.
The SPM120240D3T helps lower maintenance costs by reducing surge-related equipment damage and downtime. With a 15-year warranty (20 years if registered) and an integrated surge counter, you gain predictable lifecycle protection, improved asset longevity, and simpler asset management for capital-intensive production environments.
