Special features
Standard with surge counter
300 kA per phase surge protection is the centerpiece of the SPM300240D3T, delivering a robust defense against high-energy transients. This capability minimizes equipment insulation damage and reduces nuisance tripping downstream, translating to fewer maintenance calls and shorter repair windows. In practice, this surge protection device is ideal for critical feeds in industrial facilities, data centers, and processing lines where uninterrupted operation matters most.Configured for 240 Delta (3W+G) systems, the unit aligns with standard power distribution while preserving neutral and ground paths. The three-wire plus ground arrangement supports balanced surge protection across all phases, reducing the risk of uneven transient events. This compatibility simplifies engineering, procurement, and installation workflows for control panels and switchgear.Enclosed in a NEMA 4 enclosure with an internal terminal breaker, the SPM300240D3T is ready for rugged environments and reliable field wiring. The integrated breaker streamlines wiring, improves fault isolation, and supports safer maintenance, reducing shutdown time during routine service. Installers appreciate fewer external accessories and faster commissioning without sacrificing protection quality.Standard with a surge counter, the device provides visible status and event-traceability for preventive maintenance and asset management. RoHS compliance supports modern supply chains and multinational deployments, while UL 1449, UL 1283, and CSA certifications reinforce regulatory confidence. Together these features improve overall equipment effectiveness and lifecycle cost stability.Warranty coverage spans 15 years from delivery, with a 20-year option when registered, offering long-term protection against replacement costs. This, combined with comprehensive datasheet guidance and trusted service support, lowers total cost of ownership and supports predictable budgeting for reliability programs. The result is a robust, compliant, and cost-efficient surge protection solution for critical automation.
