Part Number: N2RS603
Manufacturer
Eaton Crouse-Hinds
Part number
N2RS603
Quick Summary
N2RS603 is an enclosed switch designed for hazardous-location motor control in industrial facilities. Operators often struggle with downtime and maintenance in harsh environments; this unit minimizes those risks with a Krydon fiberglass-reinforced polyester enclosure and a factory-sealed motor circuit switch. It complies with NEC/CEC standards and carries a Class I, Division 2 hazardous rating, plus NEMA configurations 3, 4X, 7, and 12 for versatile location protection. The 60A, 240–600 VAC, three‑pole, non‑fused design supports reliable motor control across three-phase applications while helping you meet regulatory requirements and reduce total cost of ownership. This model also aligns with common procurement workflows and spare-part standardization.
