Selling Policy 25-000 - Distribution and Control Products and Services
60 A amperage rating and three circuits provide dedicated, fused DC isolation for mid-sized solar arrays. This translates into faster fault isolation, reduced arc energy during maintenance, and a clear path to code-compliant shutdown in a turnkey installation. Applications include solar PV systems with ungrounded DC configurations where reliable disconnection is essential. 600 VDC maximum voltage and a NEMA 4X enclosure deliver rugged outdoor protection, supporting rooftop and ground-mounted installations while maintaining safe operation under varied weather conditions. The unit's lug capacity supports main wiring from #14-#2 AWG and solid returns up to #14-1/0 AWG, enabling flexible, field-friendly terminations without unnecessary splices. Enclosure material is 304 stainless steel, offering corrosion resistance in harsh environments and reducing lifecycle costs. With fusible protection and a heavy-duty switch, this DC disconnect integrates smoothly with industry-standard solar configurations, reducing retrofit risk and improving compliance with NEC and UL requirements. Compatible configurations and dimension tables explain which ampere/rating options are available, helping engineers pick the right model for each project and minimizing design-phase uncertainty.
