Eaton Specification Sheet - 556B
Brass construction provides excellent corrosion resistance and mechanical robustness, reducing maintenance needs and extending service life in challenging environments. This translates to lower lifecycle costs and fewer field replacements for coastal or wash-down applications, where reliability is critical. IP66 ingress protection guards against dust and high-pressure water exposure, ensuring continuous operation in harsh factories or outdoor installations and improving uptime for critical equipment. The enclosure dimensions—4.17 in length, 6.75 in height, and 2.47 in width with a 2 in depth—offer ample space for conductors and accessory fitments, supporting cleaner terminations and faster wiring in busy control panels. NEC/CEC compliance and Ordinary/Non-Hazardous Location classification simplify project approvals and reduce scope for special permits. Surface mounting and Pauluhn 500-series compatibility enable quick, secure installations with minimal supporting structures, boosting site productivity and reducing installation costs.
