Eaton NCB1018F NCB circuit breaker enclosure - NEMA 3/4X
Part Number: NCB1018F
Quick Summary
The Eaton NCB1018F circuit breaker enclosure protects and houses non-metallic circuit breakers in industrial control panels. It addresses the challenge of delivering rugged protection without compromising space or accessibility. Built for harsh environments, it carries NEMA ratings of 3, 4X and 12 and NEC/CEC compliance for ordinary/non-hazardous locations. Designed around Krydon fiberglass-reinforced polyester, it resists moisture and corrosion while offering easy access through a hinged, screw‑and‑gasket cover. This combination reduces maintenance cycles and keeps downtime to a minimum. In addition to compatibility with Eaton Crouse-Hinds NCB components, the enclosure supports scalable protection for modern automation architectures, helping streamline procurement and lower total cost of ownership.

The NCB1018F enclosure uses a non-metallic design to resist corrosion in damp and aggressive industrial environments, extending service life and reducing maintenance costs. This translates to fewer unplanned outages and lower total cost of ownership for long-running production lines. The Krydon fiberglass-reinforced polyester construction provides durable performance while remaining lighter than comparable metal enclosures, enabling easier handling during installation and field upgrades. A hinged, screw and gasket cover delivers quick, tool-free access for inspections and maintenance, while maintaining a robust seal that protects against dust and moisture intrusion in control panels. With dimensions of 11.41 in length, 19.41 in height, and 8.72 in width, plus a 33 lb weight, the enclosure optimizes panel real estate and supports straightforward mounting in space-constrained environments. The enclosure ships without a circuit breaker, offering flexible integration with 15A through 100A NCB-series breakers and simplifying project scoping and cabinet budgeting. Certifications and compliance, including NEMA 3/4X/12 ratings and NEC/CEC standards for Ordinary/Non-Hazardous Locations, reduce regulatory risk and streamline safe installation across facilities.
