FAQs
Ensure the panel or enclosure provides space for two module blocks and accommodates the 9.3 in length, 17.5 in height, and 14.91 in width footprint. Use the internal terminal block for clean wiring and verify the 240 Delta (3W+G) configuration matches your downstream equipment. Confirm RoHS compliance and UL/CSA certifications for the facility’s data sheet requirements.
The 400 kA per phase rating provides high-energy surge handling for each phase, reducing the likelihood of internal component damage during extreme transient events. This translates to lower maintenance costs, reduced downtime, and greater protection for motors, drives, and controllers in demanding industrial environments.
Yes. The model is specified for 240 Delta (3W+G) configurations, aligning with typical three-wire delta power distributions. In practice, this ensures appropriate protection for phase-to-phase and phase-to-ground surge events in such systems, with compatibility for standard panelboard and switchgear architectures.
The unit carries RoHS compliance and certifications including UL 1449 and CSA Electrical Notice No. 516, CSA Std. C22.2 No. 8-M1986, and UL 1283. These credentials support safe installation, regulatory alignment, and audit readiness in modern facilities.
The SPD MAX device reduces unplanned downtime and equipment failures by mitigating surge events, while the built-in surge counter enables proactive maintenance. Coupled with a 15-year warranty (20 years with registration), this translates to lower life-cycle costs, fewer field service visits, and improved asset availability in mission-critical applications.
