Eaton Specification Sheet - 545B
Durable brass construction provides long-term corrosion resistance in damp or washdown environments, reducing maintenance cycles and replacement costs while preserving signal integrity in critical control panels. This translates to lower total cost of ownership and fewer field failures in harsh facilities. IP66 ingress protection guards against dust and water exposure, minimizing downtime and warranty concerns in outdoor or exposure-prone areas, enabling reliable operations in processing plants. The surface-mount design speeds installation, reduces cabinet depth requirements, and simplifies retrofits for existing equipment, delivering faster project completion and improved workflow. With precise 4.5 in length/depth, 4.5 in height, and 3 in width, along with a 5.3 lb weight, this enclosure fits compact layouts without sacrificing access or protection. NEC/CEC compliance further assures regulatory alignment for ordinary locations, while the Brass Pauluhn architecture supports robust grounding and mechanical stability. Compatibility with Crouse-Hinds Pauluhn 500 Series resources aids procurement and spares planning, helping teams meet stringent timelines and budget targets. Industry users appreciate the proven, field-ready design for panel builders, OEMs, and service contractors who demand durable, code-compliant enclosures that install quickly and perform reliably in demanding environments.

FAQs
The 545B is a brass, surface-mount enclosure sized for 4.5 in length/depth, 4.5 in height, and 3 in width, weighing 5.3 lb. Install on flat surfaces using standard mounting methods compatible with Pauluhn 545 Series, ensuring an IP66-rated seal. Consider enclosure access, conduit entry, and gasket integrity to maintain protection in ordinary locations.
Key specs include IP66 ingress protection, NEC/CEC compliance, and ordinary/non-hazardous location suitability. Material is brass for corrosion resistance, with surface-mount capability and a 4.5 in depth/length, 4.5 in height, and 3 in width. The unit weighs 5.3 lb, providing a sturdy, durable enclosure for control wiring in industrial settings.
The 545B is rated IP66, offering robust dust and water protection suitable for many outdoor and washdown environments. However, it is intended for ordinary/non-hazardous locations per NEC/CEC standards, so for marine or hazardous-area applications you should evaluate additional protection or different enclosure options specific to those conditions.
NEC/CEC compliance helps streamline approvals for non-hazardous installations, reducing review time and changes during commissioning. Brass construction minimizes maintenance and replacement costs from corrosion, while surface-mount design shortens installation time and tooling needs, delivering faster project turnaround and lower lifecycle costs.
