FAQs
The N4-4-1200-S15-PV-NA is designed for high-current DC protection in industrial power distributions and PV installations. With a 1200 A rating and 1500 Vdc capability across four poles, it protects DC buses, motor drives, and DC power systems from overloads and short circuits. Typical use cases include solar PV DC strings, data centers with DC distribution, and heavy manufacturing panels where reliable fast-tripping is essential for uptime.
Certification status for this model should be confirmed directly with Eaton. Typical industry certifications for NZM molded case breakers include CE, UL, and IEC listings, but exact approvals can vary by model and region. Always obtain the current certificate documentation from Eaton to ensure compliance with local electrical codes and project requirements.
Replacement depends on matching the mechanical footprint, pole count, and electrical characteristics. The N4-4-1200-S15-PV-NA is a four-pole molded case breaker rated at 1200 A and 1500 Vdc, designed for NZM-style installations. Verify mounting frame compatibility, bus bar interfaces, and panel approval with the panel manufacturer or a qualified electrical engineer before substitution.
Eaton provides a warranty per policy 25-000: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. For field service, warranty coverage, and replacement parts, contact Eaton or an authorized distributor to ensure proper service documentation and trackability.
