Eaton D2CB11 30 Replacement Circuit Breaker - Hazardous

Feature: Copper-free aluminum construction. The D2CB11 30 replacement circuit breaker uses copper-free aluminum, reducing weight and corrosion risk in harsh environments common to hazardous locations. This material choice yields tangible savings in on-site handling, shipping, and installation time, especially when replacing multiple units across a panel. Aluminum also delivers robust strength under vibration and temperature cycling typical of industrial facilities. With a compact footprint (4.44 in L x 6.62 in H x 1.23 in W), it fits neatly into standard Eaton Crouse-Hinds panel installations. Feature: Factory sealed design. This unit's factory seal protects critical contacts from dust, moisture, and corrosive atmospheres, which directly lowers field maintenance frequency. That reliability translates into reduced downtime and higher line efficiency in continuous-process environments. Supplied as a ready-to-install assembly, the D2CB11 30 eliminates the need for aftermarket sealing solutions. Support for easy procurement and consistent performance across multiple sites reduces operational risk. Feature: Electrical rating and compatibility. Rated 30A at 120/240 Vac, single-pole, the assembly protects specific branch circuits without altering upstream protection schemes. Its copper-free aluminum construction keeps weight manageable during replacement in crowded switchgear. The unit's dimensions and catalog number align with existing D2CB-based installations, supporting streamlined spares and faster MTTR. Designed for hazardous locations under NEC/CEC, the D2CB11 30 is ready for rapid deployment. Feature: Certifications and standards. Compliance with NEC/CEC and Class I, Division 2 ratings is essential for audits and customer acceptance. The Hazardous/Classified Locations area classification ensures correct installation location definitions. Factory sealing and documented performance reduce regulatory risk and accelerate commissioning. The combination of these certifications with a factory-sealed design offers a reliable path from procurement to operation. Feature: Installation and procurement advantages. Catalog number D2CB11 30 matches a proven family, enabling straightforward swap-in for legacy breakers. Dimensional consistency with 4.44 x 6.62 x 1.23 in allows reuse of existing mounting hardware. Overall, this replacement assembly supports faster maintenance cycles, lower inventory complexity, and better uptime in hazardous-area protection schemes. The unit's 30A rating and 120/240 Vac compatibility cover a wide range of automation applications, from machine control to process protection.
